Coffee bags material

[Davideto]

Hi lads, this is Brown and in custom coffee bags for 6 years. I like to share my experience in this business. When you design your bags, the bag material often use aluminum foil which also known as VMPET. And the material structure usually use OPP/VMPET/PE. OPP material is for printing logo outside the bag, and PE could protect coffee bean and keep dry.The bag type usually is a stand up bag or bottom gusset bag. Another important thing is to have air valve on the bag if the coffee will storage long time. Cause air valve will keep air out and avoid coffee bean oxidation.
This is what i learn from the business, i be glad if this be a little smidgen help.
