Material selection: The material selection of coffee packaging bags is a decision-making process that comprehensively considers cost, performance, environmental protection and other factors. Common materials include aluminum foil bags, nylon bags (NY bags), polyester (PET) bags and composite material packaging bags. Aluminum foil bags can effectively isolate light, oxygen, moisture and odor with their excellent barrier properties, but the cost is high and the recycling process is complicated. Nylon bags have good barrier properties and transparency due to their high strength, wear resistance and tear resistance. Polyester bags have good transparency and fall resistance, and can effectively isolate light and some oxygen. Composite material packaging bags combine the advantages of each layer of material, which can effectively isolate light, oxygen, moisture and odor, and can reduce costs and increase recycling rates to a certain extent. 1.
Packaging form: Coffee packaging is generally vacuum or inflatable packaging. Vacuum packaging removes oxygen by vacuuming and sealing to prevent coffee from oxidizing and deteriorating. Inflatable packaging is to fill other inert gases after vacuum packaging is sealed to further remove oxygen. Both packaging methods are to exclude oxygen and prevent coffee from oxidizing and deteriorating. The latest packaging technology is to install a one-way exhaust valve on the coffee bag to avoid the loss of aromatic gases from the bag and the absorption of odors from outside the bag 2.
One-way exhaust valve: The function of the one-way exhaust valve is to allow the carbon dioxide released by the coffee after roasting to be discharged while preventing the outside air from entering, thereby reducing the oxidation of the coffee beans and retaining the flavor. This design can greatly reduce the oxidation of the coffee beans and maintain their freshness and original flavor 3.
Sealing: The sealing of the package is very important to keep the freshness of the coffee. Some packaging designs allow repeated sealing to further improve the preservation effect
