Moisture Proof Aluminum Foil Inner Bag Of Container Bag Lightproof
Liner For 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,

1. Dual-Material Versatility
This inner bag of container bag, which can be used separately or in
combination. Aluminum foil provides high barrier and lightproof
performance, while PE excels in flexibility and cost-effectiveness,
meeting the diverse packaging needs of lithium battery, food and
chemical industries.
2. Enhanced Barrier Protection
The aluminum foil version adopts a multi-layer composite structure
like PET/AL/PA/PE, achieving excellent anti-oxidation, moisture
resistance and lightproof effects. The PE version also has basic
moisture-proof performance, effectively isolating external air and
water vapor to protect packaged materials from deterioration.
3. Excellent Mechanical Durability
Both aluminum foil and PE inner bags feature high tensile strength
(≥30-100 N/15mm) and puncture resistance (≥3-12 N), with elongation
at break ≥200%. They can withstand friction, kneading and collision
during industrial handling, ensuring no easy damage to the inner
bag.
4. Full-Range Customization
We support comprehensive customization for the inner bag, including
size adjustment based on FIBC/ton bag specifications, thickness
modification according to packaging requirements, and shape
customization like cube and irregular block. Custom printing
services for logos and product information are also available. 5. Broad Industrial Applicability
Suitable for packaging lithium battery cathode/anode materials,
food powder/solids, chemical intermediates, degradable plastic
particles and nylon particles, the inner bag meets the strict
packaging standards of new energy, food, chemical and
pharmaceutical industries.
6. Eco-Friendly Production & Material
Produced in a non-magnetic physical workshop with a pollution-free
full-automatic production line, the inner bag uses food-grade and
recyclable raw materials. We also offer recyclable mono-material
options to reduce environmental impact and comply 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.
