PRODUCT INFORMATIONS

Non-Filter One-Way Exhaust Valve for Coffee Bags | Food-Grade Degassing Valve for Stand Up Pouches


Product Overview:

Freshly roasted coffee releases CO₂ for days. Sealed bags can bulge. Seals can fail. Aroma can degrade. This non-filter one-way exhaust valve solves that problem.

It works as a stand up pouch exhaust valve and a coffee bean bag degassing valve. The food grade plastic air vent valve releases CO₂. It blocks oxygen, moisture, and contaminants. Bags stay flat. Coffee stays fresh.

This coffee bag exhaust valve is built for coffee roasters, packaging manufacturers, and food brands that need reliable bulk supply.



Key Features & Benefits


  • Releases CO₂. Blocks oxygen ingress.

  • Food-grade PE material. Safe for direct food contact.

  • Sealing temperature: 163°C–168°C.

  • Works with standard heat-seal equipment.

  • Compatible with automatic and manual valve applicators.

  • Custom colors, sizes, and OEM branding available.

How It Works


  1. CO₂ builds inside the sealed bag after roasting or filling.

  2. Internal pressure reaches 2–3 mbar. The valve membrane lifts.

  3. Excess gas vents outward.

  4. Pressure drops. The valve reseals automatically.

  5. External air cannot enter. The valve opens only when internal pressure exceeds external pressure.

This prevents bag expansion, seal rupture, and oxidation. No manual intervention needed.
