As a specialty coffee roaster, you know eco-conscious customers love tactile natural kraft paper packaging. But early compostable bags often split at the side seams or let oxygen stalify delicate floral top notes within weeks. You should never have to choose between genuine sustainability and cup quality.
Our Compostable Kraft Coffee Doypack combines tactile FSC kraft paper with a high-barrier plant-derived inner bio-film and a 100% compostable degassing valve — delivering 12+ months of peak freshness and full TUV OK Compost Home certification.
Work 1-on-1 with dedicated packaging engineers to customize barrier films, optimize dieline structural integrity, and ensure zero plate fee multi-SKU printing for Kraft Coffee Doypack.
Visualize custom artwork, test gloss vs matte finishes, and calculate dynamic dieline dimensions in real-time before production.
Inspect our precision engineered 3D renders, multi-layer lamination cross-section, and automated filling line compatibility.
Reverse-printed outer film, EVOH oxygen barrier, and high-tack inner sealant layer.
Vents CO2 pressure at 3.0 mbar while blocking external O2 and moisture ingress.
Up to 80 bags/min filling line speed with 100% upright retail shelf presence.
A Compostable Kraft Coffee Doypack is a stand-up pouch made of FSC natural kraft paper laminated with a bio-barrier PLA/PBS inner layer (<1.2 cc/m²/24hr OTR) and equipped with a plant-based one-way degassing valve. Designed for 12 oz (340g) roasted whole beans, it breaks down into organic biomass in home compost within 12 months while meeting EN 13432 and ASTM D6400 global compliance standards.
Certified for home backyard composting. Zero synthetic microplastic residues.
Oxygen barrier OTR <1.2 cc/m²/24hr preserves volatile coffee aromatics for 12+ months.
Plant-based PBS valve vents excess CO₂ gas at 3.0 mbar while preventing oxygen backflow.
Featuring natural FSC brown kraft texture, soy-ink custom printing, bottom gusset stand-up stability, and an integrated plant-based zipper. Ideal for artisanal roasters looking for premium sustainable branding.
Solving real-world roastery and packaging line hurdles
Standard un-laminated kraft paper bags absorb moisture in humid storage, causing outer paper weakening and seal delamination. We co-extrude a certified bio-based High-Barrier NK Paper matrix with PBS/PLA inner lining, ensuring structural integrity at 90% RH while maintaining TUV OK Compost Home certification.
Basic PLA film exhibits high oxygen transmission rates (OTR > 50 cc/m²/24hr), causing roasted coffee beans to lose aroma in under a month. Our proprietary bio-barrier layer reduces OTR to <1.2 cc/m²/24hr and WVTR to <1.5 g/m²/24hr, extending specialty coffee shelf life to 12 months.
Freshly roasted whole beans release significant CO₂ volume. Without proper venting, sealed doypacks balloon and split at heat seals. We heat-weld a 100% bio-based compostable one-way degassing valve that releases CO₂ at 3.0 mbar while blocking oxygen ingress.
Conventional eco-zippers crack under repeated opening or lose grip when coffee dust accumulates in grooves. Our plant-derived PLA press-to-close zipper features self-cleaning micro-grooves and high tear resistance (>18 N/15mm), tested through 50+ closure cycles.
Unverified "biodegradable" claims trigger regulatory fines under FTC Green Guides and EU Directives. Every batch of Achieve Pack Kraft Doypacks includes DIN CERTCO (EN 13432) and BPI Industrial / TUV OK Compost Home certificate documentation for 100% legal compliance.
"When heat-sealing paper-based compostable laminates, roasters often suffer brittle seal tears due to uneven heat dissipation across thick kraft fibers. We engineered a modified sealing layer featuring a dual-stage melt index PBS alloy. By holding heat-seal temperature at 138°C with a 1.0-second dwell, we achieved a seal strength of >22 N/15mm while maintaining 100% home compost disintegration in 180 days."

Test natural kraft texture, heat seal strength, and plant-based degassing valves on your roastery line.
Roasting coffee releases carbon dioxide and is extremely sensitive to oxygen. We validate our degassing valve release pressure, OTR/WVTR barrier, and heat seal strength to ensure coffee aroma protection and long-term shelf life.
Tested under ASTM D3985 to preserve coffee aromatics and lock out oxygen.
Gas Chromatography-Mass Spectrometry guarantees zero odor transfer into coffee beans.
Optimized seal strength to support heavy 1kg coffee bags without seam ruptures.
Tested pressure release to expel internal CO₂ while maintaining a hermetic oxygen seal.
Prevents whole roasted coffee beans from piercing the inner laminate layers.
Sliding friction coefficient optimized for high-speed automatic bagging lines.
See how upgrading from generic commoditized bags to precision-engineered flexible barrier packaging eliminates transport failures and boosts shelf authority.
Standard stock bags fail under transit stress and expose sensitive goods to moisture, UV light, and oxygen.
Custom engineered multi-layer pouch structure tailored to your exact moisture barrier, seal strength, and aesthetic requirements.
