Cocoon Interior GrainPro

Official product name: GrainPro® Cocoon Indoor

The GrainPro Cocoon Indoor is a low-cost alternative that has all the gastight advantages of the Cocoon. It is designed for short-term use, but can be reused as long as the plastic material remains undamaged.

Made with lightweight materials, the GrainPro Cocoon Indoor acts like a large pouch, wherein commodities stored in boxes, bags or big bags are loaded through the top opening and sealed using the airtight zipper.

Light as well as easy to handle and operate, the airtight features of the GrainPro Cocoon Indoor enable it to create and maintain a low O2 / high CO2 environment for extended periods of time. This environment eliminates insects of all stages while preventing the development of aflatoxin-producing molds. Dry agricultural commodities can be stored long-term without the risk of moisture absorption and oxidation.


The GrainPro Cocoon Indoor can be customized with certain restrictions on its width and length. The perimeter of the Cocoon should be equal to a multiple of 10m (ex: 10m, 20m, 50m). No customization restrictions on height.
