What is the role of vacuum packaging bags?
1. High barrier: The co-extruded film with high barrier properties of different plastic materials can achieve high barrier effect on oxygen, water, carbon dioxide and odor.
2, stable performance: oil resistance, moisture resistance, low temperature freezing, quality assurance, preservation, odor preservation, can be used for vacuum packaging, aseptic packaging, inflatable packaging.
3. Low cost: Compared with glass packaging, aluminum foil packaging and other plastic packaging, the same barrier effect, co-extruded film has a great cost advantage. Due to the simple process, the cost of the produced film products can be reduced by 10-20% compared with dry composite films and other composite films. 4. Flexible specifications: you can meet different needs of different products.
5, high strength: co-extruded film has the characteristics of stretching during processing. After stretching, the plastic can be increased in strength. It can also be added with plastic materials such as nylon and polyethylene in the middle to make it more than ordinary plastic. The composite strength of the package, there is no delamination peeling phenomenon, good flexibility, and excellent heat sealing performance.
6. Small volume ratio: The co-extruded film can be vacuum-shrinked and the volume-to-volume ratio is nearly 100%, which is unmatched by glass, iron can and paper packaging.
7. No pollution: no added adhesive, no residual solvent pollution, green and environmental protection.
