When you consider packaging, there are several features to be aware of:
filling process
Bags with smaller openings take longer to open and fill than bags with wider openings. Whether you choose to fill bags by hand or use an automatic filling machine, make sure of the process and the time it takes.
Vent
coffee Bean bags without air valves often swell or even burst. The vent valve allows the carbon dioxide released by the roasted coffee to escape from the bean bag. It's a one-way valve: it just blows out carbon dioxide and doesn't let in oxygen. However, keep in mind that bean bags need to be completely sealed to be effective, so pay attention to the quality of the seal.

Clips or cable ties
To keep the coffee fresh, the bag should be resealable after opening. The zipper is a user friendly design that creates an airtight space. Cable ties are also available, although they cannot be sealed, they provide a good oxygen barrier and are easy to use.
coffee been bags manufacturer
When a problem occurs, it is also important that a reliable coffee bags manufacturer does not have nowhere to go and the coffee bags manufacturer can fix the problem.
Sustainability
Most coffee packaging is made of aluminum foil, paper, polyethylene and other thin layers. Since coffee is sensitive to external factors such as oxygen, moisture and UV rays, the packaging must have an insulating layer, usually a 3-layer or 2-layer sandwich. However, with the constant pressure from the public, manufacturers are bound to provide more environmentally friendly design materials.
For example, Corina says MT Pak uses cornstarch to make industrial compostable bags. "Shelf life is about 10-12 months, and of course, it's also a food-grade package." They are also printable, resistant to oil stains and UV rays, and feature a material that blocks aroma loss.
There are many factors to consider when choosing coffee packaging: cost, handling, durability, presentation, sustainability, valve, repeatability, coffee bags manufacturer, etc. But the most important thing is to understand your own needs and choose the packaging that best suits you.
