Product Details
Product Name | 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) | Suitable for two-layer lightweight packaging and three-layer composite structures made of single PP material, with emphasis on composite adhesion and barrier properties. |
VMCPP-GF | Improve the bonding strength of the aluminum layer. | Packaging for applications requiring high composite strength, such as food and pharmaceutical packages. |
VMCPP-HF | High barrier properties (oxygen barrier + moisture barrier) | Packaging for applications requiring high barrier properties and excellent composite adhesion, such as food and pharmaceutical packages (BOPP/VMCPP-HF) |
VMIPE-02 | High barrier properties (excellent moisture-barrier performance) | Suitable for single-PE materials in applications requiring high composite strength, heavy-duty packaging, and low-temperature environments. |
VMIPE-03 | High barrier properties (oxygen barrier + moisture barrier) | Suitable for single PE materials with high requirements for composite strength, stiffness, and good tear resistance. |
