Lightproof Aluminum Foil Inner Bag Of Container Bag For New Energy
Chemical Food Industrial Material 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. Enhanced Shape Adaptability
This aluminum foil inner bag of container bag can be made into
cube, irregular block and other shapes according to the storage
container and material characteristics. It fits closely with the
inner space of the container bag without leaving gaps, maximizing
the utilization of storage space.
2. Reinforced Sealing Performance
The sealing port of the inner bag adopts a heat-sealing + tying
dual fixation design, which can effectively prevent air leakage and
material spillage during transportation. It also avoids the
volatilization of chemical intermediates and the moisture
absorption of lithium battery materials.
3. Superior Temperature Insulation
The aluminum foil and VMPET composite layer of the inner bag has
good thermal insulation performance, which can reduce the impact of
external temperature changes on the packaged materials. It is
especially suitable for the storage and transportation of
temperature-sensitive lithium battery raw materials and food
powder.
4. Easy Operation & Handling
The inner bag is light in weight and flexible in texture, which is
convenient for manual or mechanical loading and unloading into the
container bag. Its reinforced lifting part design also makes the
hoisting and transferring process more stable and labor-saving.
5. Long-term Material Preservation
Thanks to the multi-layer composite structure of PET/AL/PA/PE, the
inner bag can maintain the sealed environment inside for a long
time, effectively preventing the oxidation of lithium battery
cathode/anode materials and the mildew of food solids for up to 12
months under normal storage conditions.
6. Compatibility with Multiple Filling Equipment
The inner bag is designed with a matching filling port size, which
is compatible with common industrial filling equipment such as
powder fillers and particle dispensers. It can realize fast and
accurate material filling without additional adapter parts. 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.
