Custom Flat Bottom Coffee Bags with Degassing Valve & Side Zipper

50g Custom Flat Bottom Coffee Bags for Specialty Coffee Packaging

As a professional coffee packaging manufacturer, YPAK offers 50g custom flat bottom coffee bags developed for specialty coffee roasters, coffee brands, and retail packaging applications.

This compact eight-seal pouch features a stable flat bottom, defined front and side panels, a one-way degassing valve, and a heat-sealed side zipper. The structure combines efficient product presentation with convenient access and reclosure.

One-Way Degassing Valve

The integrated one-way degassing valve allows carbon dioxide released by freshly roasted coffee to escape from the sealed pouch while limiting external air ingress.

When combined with an appropriate high-barrier laminate and properly sealed packaging, the valve supports the protection of coffee aroma and quality during storage and distribution.

Heat-Sealed Side Zipper

The heat-sealed side zipper provides a convenient reclosable opening without interrupting the main front display panel.

Its position supports easy access to the coffee after the initial opening, while the heat-sealed attachment provides a secure connection between the zipper and pouch structure.

Compact 50g Flat Bottom Structure

The 50g capacity is suitable for smaller retail portions, specialty coffee selections, promotional samples, and limited-edition product lines.

The flat bottom improves standing stability, while the defined front, back, and side panels provide space for product information, brand graphics, and customized printing.

Custom Printing and Manufacturing
