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.

1. High Barrier Performance
This double layer inner bag adopts a composite structure of
PET/AL/VMPET/PA/PE, which can effectively block oxygen, water vapor
and other external substances from penetrating into the bag. It can
keep the materials such as lithium battery raw materials and
chemical powder in a dry and isolated state for a long time, and
avoid the deterioration of materials caused by contact with air and
moisture.
2. Excellent Mechanical Strength
With tensile strength of ≥30–100 N/15mm and puncture resistance of
≥3–12 N, the inner bag has strong resistance to pulling and
piercing. It can withstand the friction and collision during the
transportation and loading/unloading of bulk materials, and is not
easy to break or leak, ensuring the safety of the packaged
materials.
3. Anti-Oxidation & Moisture-Proof
The aluminum foil and metallized PET layers in the composite
structure play a key role in anti-oxidation and moisture-proof. It
can isolate the packaged materials from oxygen and moisture in the
air, effectively preventing the oxidation, dampness and
agglomeration of materials like food powder and lithium battery
materials during storage and transportation.
4. Wide Industrial Application
It is suitable for packaging various materials in multiple
industries, including lithium battery cathode and anode materials,
chemical intermediates, plastic particles, food powder and daily
chemical raw materials. The flexible material design can adapt to
the packaging needs of different types of solid and powder
materials.
5. Customizable Design
We support customization of the inner bag's size, thickness and
material structure according to customers' actual packaging
requirements. Whether it is for large-volume bulk packaging or
special-shaped packaging for specific materials, personalized
solutions can be provided to meet the diverse needs of different
industries.
6. Environmentally Friendly & Recyclable
The inner bag is made of recyclable mono-material options and
complies with relevant environmental protection standards. On the
premise of ensuring packaging performance, it reduces the
environmental pollution caused by waste packaging materials, and
conforms to the development trend of green and low-carbon in the
packaging industry.
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.
