Structure: Back-Sealed Bag with Degassing Valve
Back-sealed construction:Features a longitudinal sealed seam along the back, creating a flat, space-efficient profile.
Integrated one-way degassing valve:Pre-installed on the front panel to release excess CO₂ from coffee beans while blocking oxygen and moisture ingress.
Heat-sealed top and bottom: Ensures a secure, leak-proof closure for long-term freshness retention.
Optional tear notch: Can be added to the top edge for tool-free opening.
Features:
Max freshness preservation: The 4-layer PET/AL/PA/PE structure + one-way valve blocks 100% of light, oxygen, and moisture, preventing coffee staling and flavor loss.
Food-safe contact: The inner PE layer is non-toxic, heat-sealable, and safe for direct contact with coffee beans.
Space-efficient design: The flat back-sealed profile reduces storage and shipping volume, lowering logistics costs.
