Double-layer Aluminum Foil FIBC

Outer Layer: Double-layer Aluminum Foil FIBC uses high-strength polyester fiber woven fabric, 120-180μm thick. It is abrasion-resistant and tear-resistant, resisting friction, impact during transportation, and outdoor sun and rain exposure, preventing bag damage. An anti-UV coating can be added as needed to extend its outdoor aging life to more than six months.

Middle Layer: Double-layer high-purity aluminum foil, 7-12μm thick, aluminum foil purity ≥99.9%. It uses a dry composite process to tightly bond with the inner and outer layers, without bubbles or delamination, providing maximum barrier performance and completely isolating moisture, oxygen, and light.

Inner Layer: Food-grade polyethylene (PE) or nylon (PA), 80-120μm thick. It is non-toxic, odorless, and corrosion-resistant, with no harmful substance migration upon direct contact with materials. It also has excellent heat-sealing properties to ensure the bag's airtightness. For special powders such as lithium iron phosphate, a thicker or puncture-resistant coating can be added.

Load Capacity: Standard 1000-2000kg (1-2 tons), customizable to 2500kg and above to meet various material loading needs.

Dimensions: Standard 1000mm×1000mm×1200mm, 1200mm×1000mm×1500mm, customizable according to container, truck dimensions and material characteristics. Dimensional deviation ≤±5%, stable stacking without tipping.

Key Performance: Water vapor transmission rate ≤0.5 g/(m²·24h) (GB/T 1037-2021); Oxygen transmission rate ≤5 cm³/(m²·24h·0.1MPa) (GB/T 1038); Surface resistivity ≤10^11 Ω, with anti-static function; Puncture strength ≥80 N; Temperature resistance range -20℃ to 80℃; Inner layer cleanliness ≥1000 grade, free of impurities and oil stains.

Environmental Standards: Compliant with RoHS and REACH environmental standards, with a material recyclability rate of ≥80%, no harmful gas emissions upon combustion, and heavy metal content ≤0.1%, meeting the needs of green industry development.

Double-layer Aluminum Foil FIBC is specifically designed for suitable industries and materials, with each scenario having undergone practical verification, ensuring maximum adaptability:

① New Energy Sector: Lithium battery positive and negative electrode materials, lithium hexafluorophosphate, NMP solvent, polysilicon, silicon ingots, etc., providing moisture and oxygen protection, anti-static properties, and ensuring material activity and purity.

② Fine Chemical Sector: Chemical powders, catalysts, pigments, dyes, pharmaceutical intermediates, etc., providing corrosion and leakage prevention, avoiding material oxidation and deterioration, and meeting chemical industry safety standards.

③ Food Raw Material Sector: Flour, starch, milk powder, cocoa powder, dehydrated vegetables, etc., with a food-grade inner layer, providing moisture and insect protection, odorless properties, and ensuring the cleanliness of food raw materials.

④ Other Applications: Provides comprehensive protection for high-value, highly sensitive materials such as precious metal powders, rare earth materials, and feed additives, reducing losses during transportation and storage.

1. Ordinary Single-layer Ton Bags: Ordinary ton bags only bear weight and lack barrier properties. Materials are prone to deliquescence and oxidation, with a loss rate typically between 5% and 10%. Our double-layer aluminum foil ton bags, with double aluminum foil barrier layers and double sealing, can control the loss rate to within 1%, and prevent material clumping and deterioration during long-term storage.

2. Competitor Aluminum Foil Ton Bags: We use double-layer high-purity aluminum foil with a more mature composite process, resulting in no delamination or bubbles, and a 30% improvement in barrier performance. The lifting straps have a higher safety factor than the industry average, providing more stable load-bearing capacity. Furthermore, by eliminating intermediate agents and supplying directly from the factory, our prices are 15%-20% lower than competitors for the same quality, making bulk purchases more cost-effective.

3. Core Advantages and Bonus Points: Can be used directly under vacuum, suitable for volatile and deliquescent materials; anti-static and puncture-resistant design avoids safety hazards during transportation; lightweight material does not increase transportation weight, reducing logistics costs; reusable 3-5 times, further reducing procurement costs.

① Specification Customization: Load capacity (500kg-5000kg), dimensions (any length, width, and height), and thickness (aluminum foil thickness, inner and outer layer thickness) can be adjusted as needed to suit your material characteristics and transportation tools.

② Material Customization: The inner layer can be replaced with food-grade PA or corrosion-resistant PE; the outer layer can be customized with wear-resistant, UV-resistant, and flame-retardant materials; the aluminum foil can be upgraded to a thicker version (12-15μm) to improve barrier performance.

③ Customizable Structure: Inlet ports (open, zipper, flange) and outlet ports (bottom, side) can be designed to meet specific needs; built-in moisture-proof layers, anti-static coatings, or customized vacuum valves can be added; the number and position of lifting straps are adjustable to suit different scenarios such as hoisting and forklift handling.

④ Customizable Appearance: Your company logo, material name, specifications, and warning labels (such as "anti-static" and "moisture-proof") can be printed on the surface. The printing is clear, durable, and enhances brand recognition while meeting supply chain traceability requirements.

⑤ OEM/ODM Customization: We support private label manufacturing, providing complete product design solutions (ODM) or production based on your existing samples and drawings (OEM). Confidentiality is maintained throughout the process, ensuring your cooperation information is not disclosed.
