Lots customers may have questions about the Roaster coffee beans bags price, the similar stand up coffee bag or similar coffee beans box pouch, why your quotation is higher or lower than the others suppliers? Except the raw material cost and quantity's factors, the most important is the printing method is different, let me do a simply explain:
On the supermarket if you pick up several bags of coffee beans, you may can meet the following flexible printing method for the coffee bags, I will for example for Matte BOPP/VMPET/PE materials 12oz stand up coffee bag :
Digital print: Digital print is a popular words in the flexible packaging industry these years, It can be summarized into two different types：
1) Full color all specs customized coffee bag: HP Indigo 20k digital press, Gaoaog Packaging solution Co.,ltd use this press digital print no need do cylinders(plates) for color printing, and not involved Knockout or Overprint, it's just like print photos, we use HP indigo ElectrInk(which has OK COMPOST HOME and TÜV AUSTRIA certificate), all of the packaging bags' specs are customized as you want( such as size, materials, thickness, shape, round corners and etc), but the production process is same as gravure printing except the made cylinder time: Choose Rollstock Raw materials for coffee bags(Matte BOPP rollstock raw material and VMPET rollstock raw material and PE rollstock raw material) - printing on MOPP rollstock raw material - Laminating the three layers roll stock film - Bakery on the curing room between 36~72hours - Cutting composite roll stock film - Making bag on the machine - Quality checking - Packaging in Box - Shipping; It suitable for small batch brand, multiple skus, One bag one QR Code, fast delivery time and it's eco friendly;
2) Simple color Simple design standard size coffee bag: by the other smaller digital printing machine such as OKI digital print press or the other digital print machine, even though also called digital print, but the production press surface print: use this machine need we prepared regularly pre-made bag at first, it means the supplier need produced lots standard size bag at first(the bag's size, materials, thickness and shaped all not customized, it's standard bag in stock without color printing or with full white or Black ot other simple color), after customers choose their standard size bag and they will directly print design on the pre-made standard size bag like the T-shirt print; It suit for simple design or just print logo customer;
Gravure print: it's a traditional print methods, generally by this way the quantity is big, and involved Knockout or Overprint, the production press is similar like HP indigo 20k print press, but need make cylinders(plates) for color printing, generally 1 color 1 cylinder, if need do spot varnish need an additional Cylinder, the make cylinder production time is about 3~5days and need purchased raw materials, so the production time is more than digital print bag; and later if reorder and the artwork no changes(include the size, design) no need pay cylinders fee again, it suitable for large quantity;
Flexo Print: this printing method is also similar like gravure print, generally the paper material prefer use this machine, and it's environmentally; The disadvantages is the color process printing has poor performance and serious dot enlargement, which is not suitable for printing products with high printing precision requirements.
Screen print: this print method it's also a traditional technology and involved Knockout print, usually by Manually, Automatic, Semi-automatic; the advantage is Convenient plate making, cheap price, easy to master technology, Manually is by hand, do a simply Screen version plate then directly print on the prepared bag's surface., but the color must need simple and can not over 3colors generally, the quality will depend on the print staff's technology. Automatic is by screen print machine, the printing lines are thick and very fine patterns cannot be printed and can not good reflect the effect for CMYK colorful;
