High Barrier Lightproof Aluminum Foil Inner Bag Of Container Bag For Lithium Battery Food Chemical Packaging
High Barrier Lightproof Aluminum Foil Inner Bag Of Container Bag For Lithium Battery Food Chemical Packaging
Based on the explosive growth of raw material products such as lithium batteries, degradable plastic particles, nylon and so on, we quickly laid out solid soft packaging business in inner bag of container bags and introduced the first full-servo high-speed automatic production line in China to improve production efficiency. At the same time, we continue to improve the characteristics of different film materials, strictly control the magnetic ad non-magnetic physical standards of the workshop, to make the inner bag is more anti-oxidation, moisture resistance, corrosion resistance, pollution-free, and give the container bag a wider range of safer material performance and application.

1. Ultra-High Barrier Performance
This aluminum foil inner bag of container bag features multi-layer composite structures like PET/AL/PA/PE, which achieves excellent barrier effects against oxygen, moisture and light. It can effectively isolate external air, water vapor and light irradiation, preventing the deterioration of lithium battery materials, food powder and chemical raw materials during storage and transportation.
2. Superior Mechanical Strength
With tensile force ≥30-100 N/15mm, puncture resistance ≥3-12 N and elongation at break ≥200%, the inner bag has strong anti-kneading and tear-resistant properties. It can withstand the friction and collision in industrial handling, loading and unloading, ensuring no damage to the packaged materials.
3. Wide Industrial Applicability
The inner bag is suitable for packaging various materials including lithium battery cathode/anode materials, degradable plastic particles, food solids/powders, chemical intermediates, daily chemical raw materials and nylon particles, meeting the packaging needs of new energy, food, chemical and pharmaceutical industries.
4. Customizable Design
We support full customization of the inner bag, including size adjustment according to FIBC/ton bag specifications, thickness modification based on packaging requirements, and shape customization such as cube and irregular block. Printing service for logos and product information is also available.
5. High Material Safety
Adopting composite materials, the inner bag is non-toxic, odorless and pollution-free. It complies with food safety and industrial material packaging standards, making it safe for contact with food powder and pharmaceutical raw materials.
6. Eco-Friendly Production & Material
Produced in a non-magnetic physical workshop with a full high-speed automatic production line, the manufacturing process is pollution-free. We also provide recyclable mono-material options, reducing environmental impact and meeting the green packaging requirements of modern industries.
The application of ton bag:
All suitable for the ton bag packaging industry, like new energy lithium battery industry, chemical raw materials, pharmaceutical raw materials, plastic raw materials, food additives, feed additives, metallurgical powder, ore powder, sand and gravel, refractory materials and so on, the container bags mainly pack block, granular or powdered items, and the physical density and looseness of the contents also have a significantly different impact on the overall result.
