Moisture Proof Food Grade Inner Bag Of Container Bag Dust Proof Liner Sack For Packaging
Moisture Proof Food Grade Inner Bag Of Container Bag Dust Proof Liner Sack For 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.

1. Barrier Performance
High barrier property with excellent resistance to oxygen, moisture and light; effectively isolates external air and water vapor, and blocks light irradiation to protect materials from deterioration.
2. Mechanical Strength
High tensile strength up to ≥30-100 N/15mm, puncture resistance ≥3-12 N and elongation at break ≥200%; strong anti-kneading and tear-resistant ability to withstand industrial handling.
3. Material Safety
Adopts composite materials; non-toxic, odorless and pollution-free, compliant with food and pharmaceutical industry safety standards.
4. Structural Adaptability
Customizable into cube-shaped, irregular block-shaped and other forms; perfectly fits the size of FIBC/ton bags for seamless inner lining use.
5. Corrosion Resistance
Resistant to corrosion from chemical intermediates, powders and daily chemical raw materials; stable material properties without reacting with packaged substances.
6. Production Standard
Produced in non-magnetic physical workshops with full high-speed automatic production lines; pollution-free process ensures consistent product quality.
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.
