COSEK white food grade ton bag, sterile and moisture-proof container bag, pharmaceutical/food special large capacity bag

1. Hygiene & Safety: Pharmaceutical-Grade Protective Barrier

COSEK food-grade bulk bags feature a double-layer composite liner: the outer layer is food-grade PP woven fabric (free from plasticizers and heavy metal migration risks), while the inner layer is high-barrier PE film (oxygen transmission rate ≤2 cm³/m²·24h·atm), completely blocking external contamination. The entire production process is conducted in a sterile environment, with gamma-ray sterilization (10-15kGy dose), complying with HACCP standards. These bags are safe for direct contact with sensitive materials like milk powder, additives, and herbal medicines, ensuring product purity.

2. Moisture Resistance: Key to Preserving Product Quality

To address spoilage risks in humid environments, these bags adopt a triple-layer protection system: "woven fabric + moisture barrier film + sealing valve." The outer woven fabric resists physical abrasion, the middle moisture barrier film prevents vapor ingress (humidity ≤40% ensures ≤2% internal moisture variation), and the top can be equipped with a dust-proof valve or vacuum system (vacuum level up to -95kPa). Ideal for export and maritime use, they prevent moisture-induced mold during shipping. Tests show only a 3% germination rate decline for rice stored for 90 days, far below the 12% loss with traditional jute bags.

3. Handling Efficiency: Designed for Automated Production Lines

The blue lifting loops use "double-strand weaving + PU coating" technology, with tensile strength ≥1200N, capable of withstanding 2-ton loads without deformation. The bag body features "four-way loops + round bottom" design, perfectly matching forklift tine spacing (standard 800-1200mm), reducing loading/unloading time by 70% compared to manual handling. For pharmaceutical companies, an "anti-static version" is available (surface resistance ≤10⁹Ω), preventing electrostatic dust adhesion and cross-contamination, meeting GMP facility requirements.

4. Custom Flexibility: Tailored to Individual Needs

We offer comprehensive customization: printing of company logos, batch numbers, QR codes (traceability system compatible); sizes ranging from 500L-2000L (standard 1000L=1m³); opening options including top, side, or valve-type (self-sealing); even temperature/humidity monitoring chips for real-time cloud data upload. All custom products pass SGS microbial testing (colony count ≤10 CFU/100cm²), ensuring customer confidence.

5. Technical Specifications: Certified Quality Assurance
