The inner lining of the COSEK food-grade FIBC bag adopts a double-layer composite structure: the outer layer is food-grade PP woven fabric (no risk of plasticizer or heavy metal migration), and the inner layer is a high-barrier PE film (oxygen permeability ≤2cm³/m²·24h·atm), completely preventing external contamination. The production process is controlled in a sterile environment throughout, and the bags are treated with gamma ray sterilization (dose 10-15kGy), meeting HACCP system requirements. They can directly contact sensitive materials such as milk powder, additives, and Chinese herbal medicines, ensuring product purity.
To address the issue of deterioration in humid environments, this bag adopts a three-layer protection of "woven fabric + moisture-proof film + sealing valve": the outer woven fabric resists physical wear, the middle moisture-proof film prevents water vapor intrusion (when humidity ≤40%, the internal cargo moisture content change ≤2%), and the top can be equipped with a dust-proof valve or vacuum device (vacuum degree up to -95kPa). It is especially suitable for export sea freight, preventing moisture and mold during shipping. Tests show that after 90 days of rice storage, the germination rate only drops by 3%, far lower than the 12% loss of traditional jute bags.
The blue lifting loops adopt a "double-strand weaving + PU coating" process, with a tensile strength ≥1200N, capable of withstanding repeated lifting of 2 tons of cargo without deformation; the bag body uses a "four-way lifting loop + round bottom" structure, perfectly matching the fork spacing of forklifts (typically 800-1200mm), reducing loading and unloading time by 70% compared to manual operations. For pharmaceutical companies, an "anti-static version" can be customized—surface resistance ≤10⁹Ω, preventing static adsorption of dust and cross-contamination, meeting GMP workshop requirements.
We offer in-depth customization services: company logos, batch numbers, and QR codes can be printed (supporting traceability system integration); sizes range from 500L to 2000L (standard 1000L = 1m³); opening options include top opening, side opening, and valve bags (with self-sealing function); temperature and humidity monitoring chips can even be added to upload data to the cloud platform in real time. All customized products pass SGS microbiological testing (colony count ≤10 CFU/100cm²), ensuring customer confidence in use.
