It’s made from a multilayer recyclable polyethylene material (PE) with a proprietary barrier layer with sufficiently low permeability to prevent air and moisture from getting in. It is designed to be used multiple times.

The GrainPro^® Hermetic Bag Farm™ has two different closing mechanisms: zipper and twist and tie. It effectively stops aflatoxin growth, eliminates infestation embedded with the commodities, and prevents the penetration by large grain borers and cowpea weevils found in the commodity without the use of harmful chemicals. It is also efficient in preserving germination quality and seed vitality. To further enhance preservation, oxygen can be removed from the bag to speed up oxygen depletion using GrainPro^® Oxygen Absorbers which are sold separately.
