Core Features
Materials and Structure: Our Jinniu manufacturer insists on using high-quality aluminum-plastic composite film as the core inner liner for our Light-proof Aluminum Lined FIBCs. The standard structure is a multi-layer co-extruded composite:
Outer Layer: High-strength polyester film, puncture-resistant and tensile-resistant.
Middle Layer: High-purity aluminum foil with a thickness strictly controlled between 7μm and 12μm. This layer achieves zero light transmittance, reflecting the vast majority of heat radiation.
Inner Layer: Food-grade polyethylene heat-sealing layer, ensuring a tight seal and preventing chemical reactions with materials.
Key Performance Parameters of Light-proof Aluminum Lined FIBCs
Water Vapor Permeability Standard: Prevents clumping and moisture absorption even in rain or high-humidity container environments.
Oxygen Permeability Standard: Effectively delays oil oxidation and material deterioration.
Puncture Resistance: The specially treated aluminum-plastic composite layer can withstand the impact of sharp-edged materials during filling, with an extremely low breakage rate.
Application Scenarios
Chemical Raw Materials: Light-proof aluminum-lined FIBC is particularly suitable for materials prone to moisture absorption and clumping, such as lithium iron phosphate, ternary materials, silane cross-linked polyethylene, and titanium dioxide.
High-Value Foods: Such as milk powder, coffee powder, cocoa powder, and food additives. These products are extremely sensitive to odor and light; the aluminum foil lining locks in the original aroma and prevents odor transfer.
Pharmaceutical Intermediates: Strictly adheres to pharmaceutical packaging hygiene standards to ensure high cleanliness.
Customization Services
Customizable Scope:
- Size: Whether it's for 90cm or 110cm cubic ton bags, or custom-made extra-large sizes for container linings, we can customize according to your size requirements.
- Openings and Valves: Customizable inflation ports, discharge ports (drainage pipes), and easy-tear lines are available.
- Printing: We offer up to 8-color gravure printing to print GHS hazard symbols, product batch numbers, company logos, etc., on the outer bag or inner lining label.
FAQ
Q: Will such thin aluminum foil tear during transportation?
A: Our aluminum foil is laminated with PE and PET, not a single thin layer. This structure can withstand repeated folding.
Q: What if I'm overseas and a quality problem arises?
A: We offer comprehensive after-sales support. First, we accept third-party inspection before shipment, and only ship goods after they pass inspection. Second, we retain samples of each batch. If a batch problem is indeed found, we will provide compensation or resend the goods according to the contract. This is our sincerity in serving our long-term international B2B clients.
Q: How are the packaging and logistics arranged?
A: Considering the large volume of ton bags, to save on your sea freight costs, we usually use compression bundling packaging. The inner lining bags are neatly folded and placed in cartons or wrapped in film, and the outer bags are also folded and bundled to maximize the use of container space.
