Moisture Resistant Aluminum Foil Inner Bag of Container Bag
Lightproof Liner for Chemical Lithium Battery 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 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. Superior Barrier Protection
Our aluminum foil inner bag of container bag adopts a multi-layer
composite structure of PET/AL/PA/PE, which delivers exceptional
barrier performance against oxygen, moisture and light. It
effectively blocks external air, water vapor and UV rays,
preventing oxidation and deterioration of lithium battery
materials, food powder and chemical intermediates during long-term
storage and transportation.
2. Robust Mechanical Strength
Boasting a tensile force of ≥30-100 N/15mm, puncture resistance of
≥3-12 N and elongation at break of ≥200%, this inner bag has
outstanding anti-kneading and tear-resistant properties. It can
withstand friction, collision and heavy handling in industrial
logistics, ensuring the integrity of packaged materials without
easy damage.
3. Broad Industrial Applicability
Designed for diverse industrial scenarios, the inner bag is ideal
for packaging lithium battery cathode/anode materials, food
solids/powders, chemical intermediates, degradable plastic
particles, nylon particles and pharmaceutical raw materials. It
meets the strict packaging requirements of new energy, food,
chemical and pharmaceutical industries simultaneously.
4. Fully Customizable Design
We offer comprehensive customization services for the inner bag,
including size adjustment based on FIBC/ton bag specifications,
thickness modification according to packaging needs, and shape
customization like cube and irregular block. Custom printing of
logos, product information and warning signs is also available to
meet brand and application demands.
5. High Material Safety & Compliance
Made from composite materials, the inner bag is non-toxic, odorless
and pollution-free. It complies with international food safety
standards and industrial material packaging regulations, making it
safe for direct contact with food powder and pharmaceutical raw
materials without contamination risks.
6. Eco-Friendly Production & Materials
Produced in a non-magnetic physical workshop with a full high-speed
automatic production line, the manufacturing process is completely
pollution-free. We also provide recyclable mono-material options
for the inner bag, reducing environmental impact and aligning with
the green packaging trends 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.
