PICS bags are chemical free safe storage technology with estimated useful life of 3 production cycles and above. Grains stored in PICS bags can stay over 2 years without losing freshness and free from any weevil attack. The PICS bags are a triple-layer bag that serves as an air-tight (hermetic) storage method. Two high-density polyethylene inner plastics fit inside an outer sack composed of woven polypropylene (PP). These inner liners greatly hinder the movement of oxygen across the wall of the bag. The tough outer woven bag enables the bag to be easily handled. The oxygen inside the bag is released upon storage and the bags are tied to minimize air circulation. Since insects respire aerobically, they require a minimum amount of oxygen to generate energy and water from their food that helps them to grow, develop and reproduce.
