Product Description

Product Name	Flexible multi-layer packaging bag specifically engineered for freshly roasted coffee, featuring an integrated one-way degassing valve that allows carbon dioxide to escape while preventing oxygen ingress to preserve peak flavor and aroma.
Material Structure	Multi-layer laminates such as PET/PE, PET/AL/PE, BOPP/PE, MOPP/PE, kraft paper/PE, or PLA/bio-based films; aluminum foil or metallized layers provide absolute barrier for long-term freshness.
Thickness Range	Commonly 50 to 200 microns (approximately 2 to 7 mils); adjustable based on product weight, puncture risk from whole beans, filling method, and desired durability for retail or bulk storage.
Bag Style	Stand-up pouches (Doypack), flat pouches, side-gusseted bags, quad seal bags, block bottom bags, or kraft paper bags; each style offers distinct shelf presence and storage efficiency.
Printing Method	High-quality rotogravure, flexographic, or digital printing supporting CMYK, Pantone (PMS), and spot colors up to 10 colors for vibrant brand artwork, origin stories, roast dates, and brewing instructions.
Surface Treatment	Glossy lamination, matte lamination, soft-touch finish, spot UV coating, hot foil stamping, embossing, or varnish to enhance shelf appeal and communicate premium or artisanal brand positioning.
Barrier Performance	Aluminum foil or metallized layers achieve OTR < 0.01 cc/m² and WVTR near zero; blocks oxygen, moisture, UV light, and odor molecules to prevent oxidation and staling of sensitive aromatic compounds.
Degassing Valve	Food-grade polypropylene one-way valve integrated into the bag face; opens under internal carbon dioxide pressure to release gas from freshly roasted beans, then self-seals to block external oxygen and maintain airtight environment.
Sealing Performance	Inner PE or CPP sealing layer enables strong heat-sealed edges; triple or quad seal configurations provide redundancy; combined with zip-lock closures for repeated airtight resealing after opening.
