Ask for sample approval before bulk production.

Factory Engineering Workflow

Real Factory Testing Process

Confirm whether the coffee is whole bean or ground coffee and the expected degassing period.
Choose valve type and locate it below the top seal but above the fill line.
Run a valve airflow test and pouch vacuum leak test after valve application.
Fill sample bags with real coffee and perform drop test and shelf observation.

Common Buyer Mistakes

Placing the valve too close to the zipper or top seal.
Using a low-barrier laminate that allows aroma loss.
Choosing a narrow bag that cannot stand after filling.

Buyer Decision Tree

Choose flat bottom pouches for premium shelf display.
Choose side gusset bags for larger 1kg coffee packs.
Use soft-touch matte when the brand wants a high-end feel.
Use kraft appearance only when the barrier layer is still included inside.
