With the development of economy, the use of vacuum packaging bags is more and more frequent, the quality is better and better, the style is more and more, more and more exquisite, but what are the characteristics of its use? Please come with me and have a look.
1. High barrier: Using high barrier properties of different plastic materials to co-extrude films, the effect of high barrier to oxygen, water, carbon dioxide, odor and so on can be achieved.
2. Stable performance: oil resistance, moisture resistance, low temperature freezing resistance, quality preservation, freshness preservation, odor preservation, can be used in vacuum packaging, aseptic packaging, air-filled packaging.
3. Low cost, flexible specifications: Compared with glass packaging, aluminum foil packaging and other plastic packaging, to achieve the same barrier effect, co-extrusion film has greater advantages in cost. Because of the simple process, the cost of the film products can be reduced by 10-20% compared with the dry composite film and other composite films. It can meet your different needs for different products.
4. High strength: The co-extruded film has the characteristics of stretching in the process of processing. After stretching, the strength of plastics can be increased accordingly. Plastic materials such as nylon and polyethylene can also be added in the middle to make it have more composite strength than that of general packaging bags. There is no delamination and peeling phenomenon. It has good softness and excellent heat sealing performance.
5. Small volume ratio, pollution-free: co-extrusion film can be packaged by vacuum shrinkage, the volume ratio is nearly 100%, which is incomparable for glass, iron cans, paper packaging, and without binder, no residual solvent pollution, green environmental protection.
