Keep Coffee Fresher, Longer — Custom Coffee Mylar Bags with One-Way Degassing Valve

FYH Custom Coffee Mylar Bags are precision-engineered for coffee roasters, brands and wholesalers who demand maximum freshness, locked-in aroma and standout retail presentation. Every bag is fully custom — printed and manufactured to order with high-barrier materials that shield your coffee from oxygen, moisture and UV light.

Key Selling Points

• One-Way Degassing Valve: Freshly roasted coffee naturally releases CO₂. The degassing valve lets gas escape while blocking oxygen from entering, so bags stay fresh, neatly puffed and safe from bursting.
• High Barrier (PET/VMPET/PE): Multi-layer lamination creates an outstanding oxygen and moisture barrier that protects whole beans and ground coffee through long storage and shipping.
• Aroma & Flavor Locking: The barrier layers seal in volatile aromatic oils, preserving the rich taste and fragrance of your roast from roastery to cup.
• UV & Oxygen Protection: Blocks harmful light and exterior air, keeping freshness, color and product integrity intact on the shelf.
• Fully Customizable: Any size, shape, finish and design — with matte/gloss lamination, clear windows, ziplock or tin-tie options to match your brand.
