Heavy-Duty Anti-Mold Vacuum Storage Bags for Bulk Rice & Grains
Our Heavy-Duty Anti-Mold Vacuum Storage Bags are specifically engineered to withstand the demanding requirements of grain storage, rice milling packaging, and long-term grain preservation. Constructed from high-tenacity PA/PE (Nylon/Polyethylene) co-extruded composite materials, these side-gusseted bags deliver exceptional puncture resistance against sharp grain husks and heavy stacking pressure during transport.
Formulated with integrated moisture-barrier and food-grade antimicrobial technology, these vacuum bags effectively eliminate oxygen and moisture accumulation—permanently preventing mold growth, grain oxidation, and insect infestation (Sitophilus oryzae) for extended shelf life.
Key Technical Advantages
- ? Tight Brick-Shaping Performance: High vacuum retention and superior elongation allow the film to conform tightly to brick mold formers, creating rigid, stackable, and space-saving rectangular packages ($1\text{ kg} – 10\text{ kg}$).
- ?️ Extreme Puncture & Tear Resistance: Multi-layer polyamide (PA) structure resists puncturing from sharp rice tips, paddy hulls, corn kernels, and rough transport handling.
- ? Anti-Mold & Insect-Proof Protection: Deprives aerobic fungi and grain pests of oxygen and moisture, preventing oxidation, rancidity, and grain yellowing during long-term warehouse storage.
- ? High-Strength Hermetic Sealing: Wide sealing temperature window ensures ultra-strong, leak-proof bottom and side seals on high-speed continuous vacuum sealing machinery.
- ? 100% Food-Grade & Odor-Free: Manufactured in ISO-certified cleanroom environments compliant with global food-contact safety standards (FDA, EU).
