QQ Studio Foil Lined Coffee Packaging Bags with Degassing Valve, 4.6 oz/130 gm Stand Up Zipper Bags with Translucent Window For Fresh Roasted Coffee Bean Storage (25, Gold)

Translucent Window- An entire wall of these bags features a full translucent display window.

This window will show off the stored contents of the bag so that everyone can see the quality of your roasted beans.

One-Way Degassing Valve- These pouches are equipped with a one-way degassing valve.

Roasted coffee beans emit small amounts of Co2 over time.

The one-way degassing valve expels this gas without allowing outside gases in.

This prevents oxidation and bulging bags.

Reliable Zipper Seal- The top of these pouches can be securely shut by pressing together the two interlocking plastic strips which come together to form a tight grip seal.

This seal can be reclosed after opening to preserve the freshness of the coffee products stored inside.

Secure Heat Seal- For maximized product security, heat-seal the bags with an impulse heat sealer.

Once sealed, the bags will be airtight and tamper-proof.

The included degassing valve will allow the gases inside to escape and the heat seal will ensure no outside gases can enter into the bag.

Durable Bottom Gusset- The bottom of these pouches features an expandable bottom gusset.

This gusset will unfold as contents are added to the bag.

This increases the internal capacity.
