Custom Eight-Side Seal Coffee Bags with One-Way Degassing Valves
Product Overview
These custom-made eight-side seal (flat bottom) coffee bags with one-way degassing valves are engineered for premium coffee packaging. The eight-side seal construction allows the bag to stand upright firmly and displays more printable surface area on the front, back, and bottom panels — ideal for shelf impact.
Built with a food-grade multi-layer barrier structure of MOPP/VMPET/PE, the bags are non-transparent, moisture-proof, and waterproof, effectively protecting roasted coffee from oxygen, humidity, and light to preserve aroma and freshness. A resealable zipper top enables convenient repeated opening and closing, while the one-way degassing valve releases CO₂ from freshly roasted beans without letting outside air back in.
Both size and color are fully customizable, and custom logo printing is accepted. MOQ starts from just 100 pieces, and samples are offered before bulk production.
