Hermetic storage materials


Hermetically sealed storage systems involves storing grains in an airtight container (e.g., drum or plastic bag, etc.) that stops oxygen and water movement between the outside atmosphere and the stored grain. The system can use special designed PVC containers such as the Cocoon™, the smaller 50kg Super bags or locally available containers made from steel, plastic, or clay. The size of the systems can range from 3 liters-2,000 tons. 

Hermetic storage systems can be used for paddy, brown rice, and other cereal crops such as corn and also coffee. Larger hermetic system have also been used with milled rice.
