Main performance | Use |
| VMBOPP-GNF | Improve the strength of the inner composite layer | Enhance the strength of inner-layer composites for solid and powder packaging; not suitable for liquid packaging. |
| VMBOPP-HF | High barrier properties (oxygen barrier + moisture barrier) Improve composite strength |
Suitable for two-layer lightweight packaging and three-layer composite structures made of single PP material, with emphasis on composite adhesion and barrier properties. Highly demanding composite packaging (when using a three-layer structure with a composite inner layer material, corona treatment is required), re- Post-assembly oxygen and moisture barrier ≤ 0.3; For example: powdered food packets, milk powder packets, biscuits and nuts, puffed snacks, pet food, etc. For example: BOPP/VMBOPP-HF/CPP or PE structure: |

Precautions for use:
During the composite processing of aluminum films, their barrier properties and bonding strength can easily be affected by factors such as the composite process itself. Please pay close attention to process control during composite operations.
