250g-1kg Eight-Side Seal Coffee Bag
The eight-side sealed coffee bag is a packaging with an eight-sided three-dimensional sealing design. It has a square shape and clear edges and corners, which is both beautiful and practical. Its multi-layer composite material (usually aluminum foil + PET + PE) effectively blocks light, oxygen and moisture, extending the shelf life of coffee. The top is equipped with a one-way exhaust valve to facilitate the release of carbon dioxide from coffee beans. The side adopts a reinforced rib structure to improve pressure resistance, and the bottom is wide and stable. It can be printed with a transparent window or matte film surface, and is equipped with a zipper sealing design for multiple opening and closing. It is suitable for 250g-1kg coffee beans/powder packaging, taking into account both display and portability.
