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.

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. |
1. Superior Barrier Performance
This ton bag inner liner boasts excellent oxygen and water vapor
barrier properties, with oxygen transmission rate as low as ≤0.5
cm³/(m²·24h·0.1MPa) and water vapor transmission rate ≤0.5
g/(m²·24h), effectively preventing oxidation and moisture damage to
packaged materials.
2. Strong Mechanical Durability
It features high tensile strength (≥30–100 N/15mm), good puncture
resistance (≥3–12 N) and anti-kneading performance, remaining
intact and not easily damaged during transportation and handling,
ensuring the safety of internal materials.
3. Diverse Material Structures
Available in aluminum foil (PET/PE surface), metallized PET and
mono-material (PE/VMPE/high-barrier PE) structures, it can be
customized with conventional four-layer or mono-material two-layer
structures to meet different packaging needs of various industries.
4. Excellent Corrosion & Oxidation Resistance
Formulated with strict control of magnetic and non-magnetic
material standards in production, the liner has strong
anti-oxidation and corrosion resistance, and is pollution-free,
suitable for packaging corrosive and sensitive chemical materials.
5. Wide Industrial Application
Ideal for packaging lithium battery cathode/anode materials,
degradable plastic particles, nylon particles, chemical
intermediates, daily chemical intermediates and food/chemical
powders, covering new energy, chemical, food and other fields.
6. Eco-Friendly Recyclability
Mono-material PE/VMPE inner liner options enable convenient
recycling and reuse, complying with industrial environmental
protection standards and reducing the environmental impact of
packaging waste.
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.
