Made from strong polyethylene with a high-barrier layer, the GrainPro Vacuum Bag keeps out oxygen and moisture, extending product shelf life. When sealed with a vacuum sealer, the bag prevents insect infestations, mold growth, and quality degradation. Frequently used in seed banks, coffee and cocoa supply chains, and for export packaging of high-value crops. Bags are reusable if handled properly and can be stored inside cartons or on pallets for added protection.
