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. | Product name | Structural composition | Product feature | Aluminum foil inner bag The surface material is PET | | It has the characteristics of anti-rubbing, not easy to break,
soft, stable overall oxygen permeability and so on | Aluminum foil inner bag The surface material is PET | | The surface material is 100% PE, it has the advantage of aluminum
foil inner bag but more soft. | VMPET inner bag The surface material is PET | | It has high tensile strength, high barrier, puncture resistance,
kneading resistance and many other mechanical properties. |
| Product name | Structural composition | Product feature | Single material inner bag The surface material is PE | | Single material, easy to recycle, with performance and other
characteristics of anti-rubbing, not easy to break, soft, stable
overall, it is also cost-effective. | Single material inner bag The surface material is VMPE | | Single material, easy to recycle, with characteristics of
anti-rubbing, not easy to damage, soft, better shading and barrier. | Single material inner bag The surface material is high-barrier PE | | Single material, easy to recycle, with characteristics of
anti-rubbing, not easy to damage, soft, it has high barrier
performance. |

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.
