Coffee Packaging Bag

Many factors need to be considered when choosing coffee packaging: cost, operation, durability, display, sustainability, air valve, repeatability, manufacturer, etc. But the most important thing is to understand your own needs and choose the packaging that best suits you. When you consider packaging, you should pay attention to the following characteristics:

(1) Filling process: bags with smaller openings take longer to open and fill than bags with wider openings. Whether you choose to fill bags manually or use an automatic filling machine, you should ensure the process and the time it takes.
(2) Exhaust valve: bean bags without air valve usually expand or even burst. The vent valve allows the carbon dioxide released by the roasted coffee to be discharged from the bean bag. This is a one-way valve: it only discharges carbon dioxide but does not allow oxygen to enter. However, please remember that the bean bag needs to be completely sealed to be effective, so the sealing quality should also be noted.
(3) Tear corner: very simple design, allowing users to open bean bags faster
(4) Clip chains or ties: To keep the coffee fresh, the bag should be resealable after opening. The clamp chain is a user-friendly design that can create a sealed space. Tie straps can also be selected. Although they cannot be sealed, they can isolate oxygen well and are easy to use.
(5) Manufacturer: When a problem occurs, a reliable manufacturer is also important, so that there is no way to help, and the manufacturer can solve the problem.

(6) Sustainability: Most coffee packages are made of aluminum foil, paper, polyethylene and other thin layers. Because coffee is very sensitive to external factors such as oxygen, water and ultraviolet light, the package must have an isolation layer, usually three or two layers. However, with the constant pressure exerted by the public, manufacturers are bound to provide more environmentally friendly design materials.
