What materials are common coffee bags made of?

The Multi-Material Coffee Bags Solution: Traditionally, coffee bags have been made from multiple layers of different materials, such as:

MOPP (Monoaxially Oriented Polypropylene)/PET (Polyethylene terephthalate): For stiffness and printability.

Aluminum Foil: For an excellent barrier against oxygen and moisture, crucial for preserving coffee freshness.

PE (Polyethylene): For heat-sealability and an internal food-safe layer.

While effective at preserving coffee, these multi-material structures are nearly impossible to recycle economically. The different layers cannot be easily separated and processed, so they end up in landfills or incinerators.

 

What materials are 100% recycled coffee bags made of?

The Mono-Material Coffee Bags Solution: Mono-material bags aim to replace these complex laminates with a structure made predominantly (usually over 95%) of a single type of plastic, typically polyethylene (PE) with aluminium-free, no foil, no metalized, no PET. 

 

Why choose 100% recyclable coffee bags?

1. Waste Reduction

The 100% recyclable bags will not end up in landfills or be incinerated, preventing them from contributing to the environmental problems caused by global plastic waste.

2. Simplified Sorting

When a mono-material bag enters a recycling facility, it's much easier for automated sorting systems (like Near-Infrared or NIR technology) to identify it as a single plastic type. This prevents contamination of recycling streams. 

3. Efficient Reprocessing

Once sorted, the mono-material plastic can be more effectively cleaned, shredded, melted, and re-pelletized into new raw material. This re-pelletized material can then be used to produce new plastic products, completing the circular loop. Also, there are very good existing recycling loops for polyethylene in many European countries. The EU is implementing new regulations like the Packaging and Packaging Waste Regulation (PPWR), which mandates recyclability by 2030 and encourages the use of single-material designs like mono-material pouches, promoting a circular economy for packaging. 

4. Enhance Brand Image and Consumer Trust

Using eco-friendly packaging demonstrates a company's commitment to social responsibility and helps cultivate a green and sustainable brand image. Consumers are more likely to support brands that prioritize environmental sustainability, especially younger generations and those with a strong environmental awareness.

 

In addition to using mono material, how can we achieve truly effective recycling?

1. Printed with 100% recycled ink

TUV Austria awarded the ‘OK Compost Home’ and ‘OK Compost Industrial’ marks to HP, verifying HP Indigo ElectroInks can be used as printing inks for packaging recoverable through composting and biodegradation in accordance with leading standards, such as EU regulation EN 13432. Therefore, digital printed inks are not only 100% recyclable but also compost.  

2. Assurance of coffee packaging sealing and printing clarity

Puncture Resistance: To protect the coffee during shipping and handling.

Seal Integrity: To prevent leaks and maintain freshness.

Printability: To allow for attractive branding and product information.

Degassing Valve Integration: Coffee degasses CO2 after roasting. Valves need to be integrated in a way that doesn't compromise the mono-material claim or recyclability. Often, it is made of food-grade plastic, such as high-density polyethylene (HDPE) or PE materials that comply with EU ROHS/FDA standards. It has good temperature resistance and chemical stability, can adapt to the normal environment of coffee packaging, and ensures safety when in contact with food.

3. Consumers' environmental awareness

People need to know how to properly dispose of these 100% recyclable bags, ensuring they end up in the correct recycling stream 

(e.g., in the USA, collect them separately and take them to designated retail drop-off points, consumers can conveniently recycle Store Drop-off Recyclable packaging at designated locations in participating retailers. 

In the EU, look for recycling locators on websites like Recycle Now to find the nearest collection points for plastic bags and wrapping) 

Can mono-material aluminum-free coffee bags really keep coffee beans fresh?

The biggest challenge of aluminum-free coffee bags is maintaining the freshness of the coffee beans while providing the same oxygen and moisture barrier properties as aluminum foil. Therefore, we offer the following innovative materials:

MDO PE (Machine Direction-Oriented Polyethylene): a advanced PE film, High density Polyethylene. With its good flatness and printing performance, excellent thermal stability and low shrinkage, MDOPE film can now be used as a printing film for flat bottom bags, spout bags, etc. To obtain MDO-PE, it is stretched in the machine’s running direction. The orientation has changed the physical properties of the PE film in such a way that it is comparable to common printing substrates, such as PET, in terms of printability and mechanical performance.

EVOH PE (Ethylene Vinyl Alcohol Polyethylene): Applying ultra-thin, recyclable barrier coatings that don't compromise the mono-material nature significantly. Perfect water barrier, oxygen barrier and gas barrier. It can effectively extend the shelf life of food, medicine and other products, and is especially suitable for items that are sensitive to oxygen and moisture.

WHITE PE (white High-Density Polyethylene): Perfect heat sealing effect can be achieved at a relatively low temperature (such as 120-180℃), which is convenient for operation of automated packaging production lines, ensuring the sealing of the packaging and preventing leakage of contents. Good chemical stability and it has low water absorption and can effectively block moisture, protecting the products in the package from moisture.

Our recycled solution is not just to make the materials "recyclable" but to make them "truly recycled" from bean to bin , contributing to a more circular economy for flexible packaging.

Have you noticed that ready-to-drink cocktails are rapidly emerging in recent years? And the RTD alcoholic beverage market is growing strongly, it will grow from US$23.13 billion in 2024 to US$25.29 billion in 2025, with a compound annual growth rate (CAGR) of 9.4%. 

The core driving force behind the rise of ready-to-drink cocktails comes from the new experience of extreme convenience, the upgrade of high-end quality and the change of lifestyle preferences that focus on health. For wine merchants, seizing new opportunities in ready-to-drink can help you solve a key challenge: balancing the convenience of packaging, reaching new markets and costs.

This blog will explore the embodiment of the ultimate convenience of spout bag in the RTD (Ready-to-Drink) wine industry, and delve into the economic benefits and RTD wine and beverage category analysis.

Why the liquid spout bag is the core embodiment of the convenience of the ready-to-drink market

The rise of RTD is not accidental, mainly because it accurately hits the preferences of contemporary consumers: extreme convenience, scene liberation, and fit in with lifestyle!

Lightness and safety

The reason why stand up pouch with spout is popular in the alcoholic beverage market is due to its friendly design that allows direct drinking and easy pouring. Compared with traditional glass bottles, plastic bottles or cans, the weight of the ready-to-drink pouch is significantly lighter and more compact. The process of shipping & storage reduces logistics costs, carbon emissions and warehousing costs.

The stand-up pouch with spout has good anti-breakage and anti-leakage effects. Flexible packaging is characterized by good flexibility and will not break easily under strong pressure. It can also safely drink wine in environments where glass is prohibited (such as swimming pools, beaches, sports events) or in environments with children. Wine refill pouch is usually made of multi-layer composite structural materials (such as BOPP-PET/AL/PE, including aluminum foil barrier layer), which can ensure the integrity of oxidation-sensitive wines (such as wine) during transportation and extend the shelf life. Importantly, the integrated spout and lid can be resealed. When customers enjoy a portion of alcoholic beverage, it can still be kept intact, reducing waste. It enhances the shopping experience and is also a very attractive point for brands!

Scene liberation

Flexible packaging for wine can save the trouble of carrying extra cups for people who need to go out, and avoid the risk of spilling drinks when drinking outdoors. Therefore, this packaging is particularly attractive to consumers who like outdoor sports, travel and small gatherings. The flexibility of the alcohol pouch makes it easy to put it in backpacks, pockets and handbags, and even put it in a cooler to enjoy cold drinks. Whether it is refreshing wine, convenient cocktails or high-end spirits, you can achieve a worry-free and easy drinking experience.

Consumers’ lifestyle changes

Consumers are paying more and more attention to health and wellness. RTD products with low sugar, low calories and simple ingredient lists are more popular with them. Real ingredients and spirit-based ready-to-drink products that avoid artificial additives are seen as symbols of high quality and “authenticity”. Millennials and Generation Z consumers dominate the alcohol market. They like to try new drinks but usually skip the trouble of mixing. For them who are savvy with social media, they will be happy to share their favorite RTD (Ready-to-Drink) spout pouches and flavors. 

Therefore, launching a series of RTD alcohol spout bag packaging products can help you stay vibrant and relevant in the fierce market competition.

 

The economic benefits of RTD alcohol packaging to wine merchants

Optimization of production costs

Spout pouch redefines the packaging materials and shipping costs of alcoholic beverages. It is made of multi-layer material and weighs only 1/10 of a glass bottle. The materials required for packaging are reduced, reducing procurement costs by 30%-50%.

The spouted liquid drink bag pouch reduces the breakage rate to below 0.5% due to its flexible and puncture-resistant material. The breakage resistance significantly reduces transportation losses. The economic losses to the company are minimized, while also giving customers a better shopping experience and enhancing their sense of trust. Empty alcoholic beverage packaging can be stacked tightly for storage, which can save more space to accommodate other materials, making effective use of storage space and reducing warehouse rental costs.

Enhance brand image and marketing opportunities

Stand up pouch with spout packaging uses less raw materials than rigid packaging, which reduces the consumption of earth resources and alleviates ecological damage. Drink spout pouch is light in weight and can carry 3-5 times more than rigid packaging under the same capacity of transportation vehicles. The number of shipping times and fuel consumption are reduced, which reduces carbon emissions. Combined with the use of recyclable material packaging solutions, it can also cater to consumers' pursuit of sustainability and enhance the brand's image and appeal in terms of environmental protection. Spout pouch bag has a larger printing area to display more product information, attracting young consumers who are looking for fresh experiences.

Supply chain and channel management optimization

For new product development, cost control and efficiency optimization are key. The initial investment is relatively large, especially when rigid packaging is used. The alcoholic beverage packaging spout pouch has more significant advantages in this regard: low minimum order quantity, low printing costs, and is suitable for wine merchants with small batch customization needs. Lightweight and flattening can alleviate the pressure of goods hoarding and optimize warehouse management. Of course, liquid spout pouch is a flexible packaging, which can reduce product loss during transportation, reduce compensation and rework rate, and improve the overall profit margin and market competitiveness of new products.

Ready-to-drink (RTD) alcohol type analysis

Ready to drink pouches have significant advantages in the RTD alcoholic beverage market. They can meet the needs of convenience and portability, allowing consumers to enjoy alcoholic beverages or pre-mixed cocktails at home or on the go. Alcoholic beverages in the RTD market can be divided into three categories:

Malt-based drinks

Hard Seltzer and other beverages, including hard kombucha and hard tea, are made from malt fermented to produce alcohol. Compared with other products, they are usually lower in calories and sugar and retain a refreshing fruity taste. Most products have an alcohol content of 5%-12% ABV, suitable for consumers who pay attention to health and alcohol flavor.

Wine-based ready-to-drink

In this category, you'll find pre-mixed grape cocktails and sparkling wines, and even wine sodas. Their alcohol content is usually around 5%-14.5% ABV. Specific types include mulled wine, Sangria, and summer wine. Popular brands such as Lt. Blender's "Sangria in a Bag" are mixed cocktails made with red wine as the base.

Liquor-based drinks

The most familiar ones should be ready-to-drink cocktails. A variety of flavors meet the different preferences of consumers and dominate the ready-to-drink market. Other drinks mixed with liquor, such as soda water with liquor, Shooters. The common point of all three is that they are made with liquor (whiskey, tequila, gin, vodka, rum, etc.) as the base. But the difference is that cocktails emphasize flavor balance and visual presentation, soda water highlights the original flavor of liquor and has a lighter taste, and shot wine can quickly get the "impact" of alcohol, so this type of alcoholic beverage is probably between 10%-50% ABV.

When a new product is born, packaging is its "first language", from the material, printing texture, to the way it is opened. Choosing a partner with both stable supply chain and reliable production process is the key. The new alcohol pouches  are not only the ultimate convenience of ready-to-drink, but also a new opportunity to open up the young market and enhance brand vitality.

How to choose the right packaging?

When choosing product packaging, consider multiple factors, including product characteristics, shipping methods, brand positioning, and functional requirements.

Product Features

Liquids (beverages, sauces) are ideally suited for spout pouches, which offer convenient storage and pouring, and are leak-proof. Fragile products or those requiring moisture protection (biscuits, powders, cereals) are best suited for stand-up pouches or flat-bottom bags. Aluminum foil has excellent barrier properties and is light-proof, which can prolong the freshness of products. Large-volume solid products (coffee beans, pet food, cat litter) are best suited for flat-bottom bags or gusseted bags, which offer excellent load-bearing performance.

Shipping Methods

International shipping requires waterproof, damage-resistant, and crush-resistant construction. Gaoaog Pack has been in the industry for nearly a decade, continuously exploring innovative materials and technologies to safeguard every customer's product. We offer a variety of packaging materials to ensure the contents remain intact, even during lengthy shipping processes. Lightweight courier bags are ideal for small express shipments. They take up minimal space and weigh little, ensuring product safety while helping businesses reduce costs.

Brand Positioning

High-end brands can choose flat-bottom bags or slider zipper bags for visual appeal. Beautiful packaging fosters a sense of anticipation and security, thereby boosting word-of-mouth. Eco-conscious businesses can opt for 100% recyclable pouches. Eco-friendly color schemes and minimalist designs signal sustainability and authenticity, appealing to conscious consumers.

Functional Requirements

Using tear notches, zipper locks, view windows, and spouts on packaging can bring the product closer to consumers. E-commerce packaging needs to be distinctive to attract customers, and high-quality design can increase repeat purchases.

Key Points for Custom E-commerce Packaging Design

Use consistent brand logos, colors, and fonts to align the packaging with your brand story and values. Clearly communicate product information on the packaging. Highlight the brand name and key product features on the front, and detailed product information on the back.

User-friendly design and craftsmanship. Easy-tear tabs, a resealable zipper, a suction nozzle, and a laser tear line enhance the user experience. High-definition digital printing, hot stamping, and spot UV treatments add a touch of class to the packaging.

Choose environmentally sustainable packaging solutions. With consumers' growing environmental awareness, sustainable packaging has become a crucial component of brand image building. Choose easily recyclable materials like mono-material PE and clearly label the packaging with recycling symbols or environmentally friendly instructions. These small labels guide consumers in the proper disposal of discarded packaging. While ensuring the protective properties of the bag, minimize material consumption. Lightweight packaging also reduces carbon footprint.

When transporting products, choose packaging that is wear-resistant and of matching size. E-commerce packaging faces challenges such as rough sorting, multiple transports, and long, bumpy journeys. For heavy and fragile items, multi-layer composite film structures are used, offering puncture resistance and high toughness to prevent crushing and scratching during transport. For food and pet treats, flexible packaging with moisture-proof and waterproof barrier layers protects the product from moisture, spoilage, and external liquids. Similarly, double heat seals or reinforced zippers can prevent openings during transport. It's also crucial that the packaging fits the product as closely as possible, avoiding excessive gaps that could cause product movement and damage.

Packaging opening is simple, ensuring no damage or hassle. A pleasant unboxing process can increase users' favorability towards the brand and increase social media mentions. Easy-tear notches are essential, and high-quality, smooth zippers also enhance user experience.

In the colorful world of e-commerce, packaging is no longer just a coat to protect the product. It represents your brand’s attitude，ensures product safety, and delivers a strong first impression. Whether it’s stand-up pouches, flat bottom bags, frosted zipper bags, or durable mailer bags, choosing the right type of flexible packaging with your own branding can set your business apart.

With the quickening pace of modern life, people's preference for convenience foods has increased. "Convenience" and "immediacy" are key to the consumer market，and the same is true for the alcohol market. In the past, people needed to prepare wine bottles and glasses, as well as tools for opening and decanting wine (e.g：red wine). This was too troublesome for people who wanted to be ready to drink alcohol. For this type of consumers, we can consider innovative packaging to simplify the drinking process.

A novel functional alcoholic beverage packaging solution appeared in front of everyone--spouted pouches (also known as liquid pouch or fitment pouch). Drink pouches are ideal packaging for wine and other alcoholic drinks. It was first used in the food industry, such as small packaging bags for jelly, puree and juice. What changes would occur if a liquor company updated its alcohol packaging to spout bags?

 

The benefits that alcoholic pouch drinks bring to consumers：liquor on-the-go, enjoy drinks anytime and anywhere.

The alcohol spout pouch packaging provides a lot of convenience. It is not only lightweight but also very easy to carry. Make adult drinks easy to drink and store. The most important thing is that it is very convenient to pour out and drink. Once the alcohol is opened, it can be re-sealed to keep the taste of the alcohol fresh and to minimize waste. For examples：

• If you want to go on a picnic, hike, camp, boat or other outdoor activities, this kind of small bag and light weight adult drink pouch is an ideal choice. It is not limited by the scene and can be stuffed into your pocket at will.

• Alcohol drinks in bags are made of bags and tamper-proof caps, so you don't need to use a wine opener or other tools to drink. There are a variety of small-capacity liquid spout bags for consumers to choose from, so that consumers can enjoy the fresh flavor of a small drink. This can avoid the waste caused by the loss of flavor after opening large-capacity alcoholic drinks. 
• The portable alcoholic packaging is made of high-strength composite material (MOPP-PET/AL/PE), which is an ideal material for protecting liquid beverages. Spouted pouch alcoholic beverages has good compression resistance and leak-proof properties. If your wine pouch accidentally falls out of your pocket, don't worry about it cracking or bursting. We have tried very violent ways to drop it and there were no signs of damage.  

• The design elements of flexible packaging spout bags can be very rich. Consumers who pursue novelty and personalization may share this new experience on social media. The stand-up spout pouch packaging design providing a simpler and more convenient way for customers with needs during outdoor activities and commuting. As the contents are consumed, its volume decreases accordingly, which can reduce the weight of the backpack. Compared with other liquor packaging, spout pouch packaging is more likely to win the favor of outdoor sports enthusiasts. 

 

Wine merchants benefit from the spout pouch: Achieve higher-quality packaging at a lower cost.

Compared to traditional glass bottles, it significantly reduces packaging, shipping and breakage costs, and also reduces the carbon footprint. According to the U.S. Environmental Protection Agency (EPA), the glass recycling rate in the U.S. is about 31%-33%. This means that a large number of glass bottles (including alcohol bottles) end up in landfills. Therefore, liquid beverage bags can help your company achieve sustainable development goals. 

• Reduce the costs : Packaging is about product positioning and creating consumer interest and consists of multiple components that can provide benefits to packaging. Compared with other packaging products, spout pouch packaging uses less materials, has lower material costs, and occupies less space. For small manufacturers with financial pressure, it is the best alcohol packaging for shipping. The drink pouch is lighter and more compact, which means more products can be transported, reducing freight and fuel consumption. The advantage of fitment pouch is that it is flexible, which can reduce the damage rate during transportation and avoid unnecessary cost losses.

• This stand-up spout pouch is considered eco-friendly by addressing the first need in the hierarchy of sustainability, which is the reduction of material. If you are interested in environmentally friendly alcohol packaging solutions, you will also gain the favorability of modern consumers for environmentally friendly products. It will help you establish a differentiated brand image for your liquor beverage products. 

• Novel alcoholic beverage spout packaging can help products stand out on the shelf. This type of nozzle packaging allows for greater design flexibility and creativity, helping to attract customers who value convenience and innovation. (e.g: special shapes, bright colors, etc.)
• Ready to drink (often known as RTD) packaged beverages are those sold in a prepared form, ready for consumption. Especially in informal occasions, drinking is more convenient and can improve consumer satisfaction. Upgrading the packaging of alcoholic beverages is also a manifestation of brand vitality, which plays a significant role in enhancing the brand image. So upgrading the packaging of alcohol drink is of great benefit to your entry into the outdoor ready-to-drink market. 
• The fitment pouch material can be made of a single PE composite material (e.g：PE/EVOH-PE) with a recycling rate of up to 100%. The high barrier material of the pouch spout provides good protection for the wine, blocking oxygen and light. It is very good to maintain the fresh taste of the wine. The resealable drink pouch can extend the shelf life of wine and alleviate the loss of wine flavor, which is also the company's selling point.

When you are planning to customize coffee bags, you will definitely think of optional-addons, such as a zipper and one way degassing valve. As we all know, the function of a zipper is to reseal to ensure the freshness of coffee beans, so why do coffee bags have a valve? 

The construct of degassing valve: 

First of all, the core design logic of the coffee bag degassing valve is one-way conduction, that is, only the gas in the bag is allowed to be degassed, while blocking the outer air from entering. Secondly, most common coffee bag degassing valves are flexible diaphragm one-way valves, which are mainly composed of four key parts:

Filter Mesh: Prevents coffee grounds from clogging the 5 degassing holes.

Valve Body: The circular base is fixed on the surface of the coffee bag, with 5 degassing holes in the center, which is the channel for gas to enter and exit. It is made of food-grade plastic and is sealed with the bag body to avoid air leakage.

Flexible Diaphragm: A thin sheet structure covering the degassing holes of the valve body, with its edge tightly fitting the valve body to form an initial sealing state. The elasticity of the diaphragm is the key to one-way conduction - When it is subjected to the pressure of the gas in the bag, it will be pushed, forming a gap between it and the valve body, opening the degassing channel; after the pressure disappears, the external gas will exert pressure on the diaphragm and block the degassing holes.

Cover: The cover has grooves around it to allow air to pass through, and the four corners can be inserted into the valve body, which can not only prevent the diaphragm from being contaminated by external debris, but also guide the degassing gas to diffuse smoothly into the air, while preventing external dust from entering the valve through the degassing holes. 

How does a one way valve work?

1. Let carbon dioxide out

After roasting, whole coffee beans will continue to release carbon dioxide (CO₂) over several days or even weeks . As the gas accumulates in the bag, the air pressure in the bag gradually increases. When the air pressure reaches a certain threshold (usually 0.1-0.3bar, the specific value varies depending on the valve type), the thrust of the gas on the flexible diaphragm will overcome the pressure of the external air pressure, so that the edge of the diaphragm is separated from the valve body, forming a tiny gap. At this time, the carbon dioxide in the bag passes through the gap between the diaphragm and the valve body, and then degassed from the bag through the 5 air holes of the valve cover. As the carbon dioxide is degassed, the air pressure in the bag drops. When the pressure is lower than the threshold, the diaphragm will fits tightly with the valve body again. There is no gap between the flexible diaphragm, thus closing the degassing channel. 

2. Prevent oxygen and moisture from entering

When the air pressure inside the bag is equal to the outside air pressure, the flexible diaphragm always maintains a close fit with the valve body. If the outside air tries to enter the bag at this time, it will exert inward pressure on the diaphragm, which will make the diaphragm fit tightly with the valve body. Even if there is a slight fluctuation (such as shake during transportation, changes in ambient air pressure), the diaphragm can ensure the closing state, thereby completely blocking oxygen, water vapor and other outside gases from entering the bag, preventing the coffee from deteriorating due to oxidation or moisture. 

Disadvantages of coffee bag without degassing valve:

1. The buildup of carbon dioxide produced by the coffee beans will cause the bag to inflate like a balloon and eventually burst.

2. Carbon dioxide accumulation affects the flavor of coffee and odor. 

3. It is not conducive to maintaining the freshness shortens the shelf life. 

Situations where a valve is unnecessary: 

1. Ground coffee powder: Typically, ground coffee (pre-ground coffee) has already finished degassing by the time it gets sealed.

2. Nitrogen flushing: Some large-scale commercial operations (such as coffee canning) remove all oxygen and flush the container with inert nitrogen before sealing.

So, the importance of one way degassing valve has two main point, that is let CO2 out and prevent oxygen and moisture from entering. To ensure your whole coffee beans are still fresh when they reach your customers, contact us to ask a small tiny one-way degassing valve on your custom coffee bag! 

The coffee market is expected to reach US$96.45 billion in 2025 in terms of at-home consumption (revenue generated in supermarkets and convenience stores) In such a large market, how can coffee companies stand out? In order to ensure the freshness of coffee beans, the oxygen barrier properties and light barrier properties of the coffee packaging must be carefully considered. Usually, aluminum foil and metallized film, that is VMPET (Vacuum Metalized PET) are considered better coffee pouches materials. 

So, what do they have in common and what are their differences? 

Commonalities

First, let’s go with OTR and WVTR, which are effective assessments of coffee packaging material quality. 

Oxygen transmission rate (OTR)

OTR is the volume of oxygen that passes through a material over a given period of time, usually expressed as milliliters per square meter per day at standard temperature and pressure (mL/m²/24h at STP). It is of great importance in the packaging of processed foods and it is critical that headspace oxygen is excluded (Kumar, 1994). 

Water Vapor Transmission Rate (WVTR)

Moisture vapor transmission rate (MVTR), also water vapor transmission rate (WVTR), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers. Moisture sensitive foods and pharmaceuticals are put in packaging with controlled MVTR to achieve the required quality, safety, and shelf life. 

Parameters (N=51)	Aluminum (un-flexed)	MPET (un-flexed)
OTR	0.06571	0.2283
WVTR	0.00873	0.21408

*Optimal barrier properties of Aluminium and MPET (un-flexed) under 180 day shelf life

The European and American markets have requirements for the barrier properties of coffee packaging (such as oxygen permeability <1cm³/(m²・24h・0.1MPa) and water vapor permeability <1g/(m²・24h)), which directly affect the shelf life of coffee beans (flavor loss must be <5% within a shelf life of 6-12 months). 

In summary, aluminum and MPET(VMPET) both have almost zero Oxygen Transmission Rate (OTR) and Water Vapor Transmission Rate (WVTR), making it an excellent barrier against external elements. 

Differences

Appearance 

Aluminum: has a matte property, and when the outermost layer is PE, it presents a matte effect. Some customers like the matte effect because the bag looks more advanced and has a better texture. 

VMPET: has the characteristic of being glossy effect. Light reflectivity up to 97%, and if the outermost layer is PE, the packaging surface will be shiny and reflective. The shiny bag will be more dazzling and make the packaging more eye-catching. 

Cost

Aluminum: the cost of coffee bags made of pure aluminum foil is relatively high. Pure aluminum foil has best barrier properties and can effectively prevent oxygen, moisture and UV-light. It is a good choice for companies with sufficient budget or pursuing high-quality gourmet coffee beans.

VMPET: is aluminized film, which is a composite material formed by coating a very thin layer of metal aluminum on the surface of a plastic film. Its base material is a polyester film (PET), and the cost is relatively low. In addition, the metallized film process can greatly reduce the amount of aluminum used. Compared with pure aluminum foil, the aluminum consumption of VMPET is about 1/140-1/180 of that of aluminum foil, thus reducing the cost. 

So, in the case of equal area, the material cost of VMPET is 70% or even 50% of pure aluminum. 

Recyclability

Can aluminum foil be recycled? This is a question that many people are concerned about.

Aluminum: The recycling process is relatively simple. When pure aluminum is recycled, it only needs to go through routine steps such as sorting, cleaning, crushing, and smelting to be made into new aluminum products.

VMPET: Recycling is difficult. VMPET is a composite material formed by coating a very thin layer of metal aluminum on the surface of a polyester film. When recycling, the metal aluminum and the polyester film must be separated first, which increases the complexity and cost of recycling. At present, chemical recycling or physical recycling methods are usually used for the recycling of VMPET, but these methods have certain technical difficulties and high costs.In some places, VMPET is treated as ordinary garbage and is not effectively recycled.
