Features of multi-layer co-extrusion EVOH film

Features of multi-layer co-extrusion EVOH Shrink Film

1. High barrier: Different products have different requirements for the barrier properties of packaging. Co-extrusion film technology can optimize film performance, properly distribute barrier and strength or other functional applications, and realize the advantages of multiple functions in one film, even though the combination of different materials for barrier properties achieves a high barrier effect on oxygen, water, carbon dioxide, and odors.

2. Strong function: Multi-layer co-extruded Evoh Shrink Film can realize various functions such as oil resistance, moisture resistance, high-temperature cooking resistance, low-temperature freezing resistance, and odor resistance by adjusting the ratio of raw materials, to meet the packaging needs of different products.

3. Low cost: Compared with glass packaging, aluminum foil packaging, and other plastic packaging, if you want to achieve the same barrier effect, multi-layer co-extrusion Shrink Film can reduce the cost by 20% -30% compared with other composite films due to the simple process. Thereby reducing the cost of packaging for production enterprises and reducing product costs.

4. High strength: During the processing of multi-layer co-extrusion film, different raw materials can be added to make it have the characteristic of stretching, and the strength of the plastic after stretching can be increased accordingly. Plastic materials such as nylon and resin can also be added in the middle to make it have a composite strength exceeding ordinary plastic packaging, will not delaminate, and has good flexibility and good heat-sealing performance.

5. No pollution: no binder, no residual solvent pollution, green and environmental protection.
