High Barrier Lightproof Moisture Resistant Aluminum Foil Inner Bag
of Container Bag for Lithium Battery Chemical Food 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 name | Structural composition | Product feature | Aluminum foil inner bag The surface material is PET | | It has the characteristics of anti-rubbing, not easy to break,
soft, stable overall oxygen permeability and so on | Aluminum foil inner bag The surface material is PET | | The surface material is 100% PE, it has the advantage of aluminum
foil inner bag but more soft. | VMPET inner bag The surface material is PET | | It has high tensile strength, high barrier, puncture resistance,

1. Ultra-High Barrier Performance
Crafted with multi-layer composite structures like PET/AL/PA/PE,
this aluminum foil inner bag of container bag delivers exceptional
barrier effects against oxygen, moisture and light. It fully
isolates external air, water vapor and UV rays, effectively
preventing the oxidation and deterioration of lithium battery
materials and chemical raw materials during long-term storage.
2. Versatile Customization Options
We provide comprehensive customization services for the inner bag,
including size adjustment to fit different FIBC/ton bag
specifications, thickness modification based on barrier needs, and
shape customization for cube, irregular block or special-shaped
designs. Custom logo printing is also available to meet brand
promotion demands.
3. Robust Mechanical Durability
With a tensile force of ≥30-100 N/15mm, puncture resistance of
≥3-12 N and elongation at break of ≥200%, the inner bag has
outstanding anti-kneading and tear-resistant properties. It can
withstand the friction, collision and heavy loading in industrial
logistics without easy damage. 4. Broad Industrial Compatibility
Designed for diverse industrial scenarios, the inner bag is ideal
for packaging lithium battery cathode/anode materials, food
powder/solids, chemical intermediates and nylon particles. It meets
the strict packaging standards of new energy, food, chemical and
pharmaceutical industries simultaneously.
5. Premium Material Safety
Made from composite materials, the inner bag is non-toxic,
odorless and pollution-free. It complies with international food
safety and industrial material packaging regulations, ensuring safe
contact with food powder and pharmaceutical raw materials.
6. Eco-Friendly Production & Materials
Produced in a non-magnetic physical workshop with a fully automated
pollution-free production line, the inner bag uses recyclable
aluminum foil and PE raw materials. We also offer mono-material
recyclable options to reduce environmental impact and align with
green packaging trends. 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.
