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. | Product Type | Inner Bag of Container Bag/Ton Bag | | Material Structure | PET/AL/PA/PE;PE/AL/PA/PE; PET/VMPET/PE | | Core Features | Anti-oxidation, moisture/corrosion resistance, anti-kneading, high

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.
