Product Description
Hermetic Bags are the world’s most effective, chemical-free storage solution for green coffee, maize, rice, beans, cocoa, nuts, and all dry agricultural commodities. Manufactured from high-strength multi-layer plastic with an ultra-low oxygen permeability barrier (OTR < 2 cc/m²/day), they create a 100 % airtight, pest-proof seal that stops insects (including weevils and grain borers) dead in their tracks without any fumigation. After sealing with a simple cable tie or heat sealer, oxygen drops below 1 % within days, preserving quality, weight, and germination for 12–36 months. Trusted by WFP, USAID, FAO, major coffee exporters, and millions of smallholder farmers across Africa, Asia, and Latin America.
