Coffee is usually sold in the form of coffee beans or instant coffee. Coffee beans require excellent barrier parts in their packaging, and aluminum foil bags with one-way air release valves or paper-plastic composite bags are more commonly used. Instant coffee is mostly made into small packages with aluminized film or aluminum foil composite film on automatic packaging machines.
The packaging materials for tea are similar to coffee. They are mostly packed in aluminized bags or aluminum foil bags. In addition, some tea packages require a vacuum function, and nylon materials are added to the bags.
Regular packaging bag material for coffee and tea:
- Moisture-proof Bag：OPP、PET + LDPE
- Light-proof Bag：Metallic film、Aluminum foil + LDPE
- Paper Laminated Bag：Paper/PET/LDPE
