High-Barrier Container Bag Inner Liner Ton Bag
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 High Barrier Performance
This container bag inner bag is made of PET/AL/PA/PE and VMPET
composite materials, which provides excellent barrier against
oxygen, moisture and light. It can effectively prevent the
oxidation and deterioration of lithium battery materials, food
powder and chemical particles, and maintain the stability of the
packaged materials for a long time.
2. Excellent Mechanical Strength
With a tensile force of ≥30-100 N/15mm and puncture resistance of
≥3-12 N, the inner bag has strong anti-kneading and wear
resistance. It can withstand extrusion, collision and kneading
during transportation and handling, and is not easy to break or
leak, ensuring the safety of materials.
3. Diverse Material Structure Options
We offer multiple material structures such as PET/AL/PA/PE,
PE/AL/PA/PE and PET/VMPET/PE, as well as single-material PE
structure. Different structures can be selected according to the
characteristics of packaged materials like food, chemicals and
lithium battery raw materials.
4. Wide Industrial Application Range
The inner bag is widely used in packaging lithium battery cathode
and anode materials, degradable plastic particles, food powder,
chemical intermediates and daily chemical raw materials. It meets
the packaging needs of new energy, food processing, chemical
manufacturing and other industries.
5. Customizable Design Service
We support customization of size, thickness and material structure
according to customers' actual needs, and also provide logo
printing service. The surface material can be customized to match
different usage scenarios.
6. High-standard Production Process
The inner bags are produced by a full high-speed automatic
production line, and the workshop complies with non-magnetic
physical standards. The production process is pollution-free, which
ensures the consistency and high quality of the products, and meets
the strict requirements of industrial production. 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.
