Manufacturing Authority Note: At OG Hemp’s manufacturing facility in Kolkata, our technicians conduct tensile, burst factor, and moisture tests across every production run to ensure ISO standard compliance and real-world packaging durability.
What barrier layers are used to make compostable pouches moisture and oxygen proof?
Compostable bio-pouches utilize certified bio-polymer barrier laminates like PLA (Polylactic Acid), PBS (Polybutylene Succinate), and metallized NatureFlex cellulose films. These plant-derived layers provide high Oxygen Transmission Rates (OTR < 2.0 cc/m²/day) and Water Vapor Transmission Rates (WVTR < 5.0 g/m²/day), protecting coffee beans, matcha, and organic botanicals from oxidation without petroleum foils.
Are bio-laminated hemp stand-up pouches heat-sealable on standard commercial machinery?
Yes, compostable plant-based pouches seal seamlessly on standard heat-sealing machines at 120°C to 160°C. They support hermetic heat sealing, resealable plant-based zip locks, tear notches, and one-way compostable degassing valves for fresh roasted coffee degassing.
How fast do plant-based barrier pouches decompose in commercial and home compost?
Certified plant-based bio-pouches break down within 90 to 180 days in commercial compost (EN 13432 & ASTM D6400 standards), turning into nutrient-rich biomass, water, and CO2 without leaving synthetic microplastic residues or chemical toxins behind.
