Question 1

Why do coffee bags need a degassing valve?

Accepted Answer

Fresh roasted coffee can release carbon dioxide after packing. A degassing valve helps release gas from the bag while reducing outside air entering the package, which helps protect aroma and reduce bag swelling risk.

Question 2

What bag types are commonly used for coffee packaging?

Accepted Answer

Common coffee packaging formats include flat bottom coffee bags, stand up zipper pouches, side gusset bags and kraft paper laminated coffee bags. The choice depends on filling weight, shelf display, zipper requirement and brand design.

Question 3

What material structure is suitable for coffee bags?

Accepted Answer

Coffee packaging often needs good aroma, oxygen and moisture barrier. Common structures may include PET/VMPET/PE, PET/AL/PE, kraft paper laminated structures or other high-barrier options. The final structure should be confirmed based on shelf life and storage condition.

Question 4

Can coffee bags be customized with zipper and matte finish?

Yes. Coffee bags can be customized with zipper, degassing valve, matte finish, glossy finish, kraft paper surface, rounded corners and custom printing. The exact options depend on bag type, size and order requirements.
