Moisture Proof Multi Layer Structure Inner bag of Container Bag For Chemical Powder Food Solids Storage
Moisture Proof Multi Layer Structure Inner Bag Of Container Bag For Chemical Powder Food Solids Storage
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. Ultra-high Barrier Protection
This container bag inner bag adopts PET/AL/PA/PE and VMPET composite structures, which achieves excellent barrier effects against oxygen, moisture and light. It can effectively isolate external air and moisture, preventing the deterioration of lithium battery materials, food powder and other sensitive materials during storage and transportation.
2. Robust Mechanical Durability
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 the extrusion, collision and repeated handling in industrial transportation, and is not easy to tear or leak, ensuring the safety of packaged materials.
3. Versatile Material Structure Options
We provide multiple material structures including PET/AL/PA/PE, PE/AL/PA/PE and PET/VMPET/PE, as well as single-layer PE structure. Different structures can be selected according to the characteristics of materials like lithium battery raw materials, food solids and chemical intermediates.
4. Broad Industrial Applicability
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 perfectly meets the packaging demands of new energy, food processing, chemical manufacturing and daily chemical industries.
5. Flexible Customization Service
We support personalized customization of size, thickness and material structure for the inner bag, and also offer surface material customization and logo printing service. This allows the product to be tailored to the specific usage scenarios and brand needs of customers.
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 with a pollution-free production process. This ensures the consistent quality and high performance of each product, meeting 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.
