Vacuum bag

Vacuum bag Vacuum bag packaging, which is also called decompression of the air inside the container will all spare seal, maintain the bag in height, air pressure, low oxygen equivalent effect of rare survival conditions that microbial not to decay, fresh fruit of purpose. Since about vacuum packaging materials, it is essential to the classification of the material, it is suitable for various material characteristics of vacuum packing: one, including the use of suitable for low temperature, PE RCPP for high-temperature cooking makes, Second, in order to increase the physical strength is PA, durable thorn performance, Third, AL foil is to increase the barrier properties, shading, Four, PET, increase mechanical strength, superior. Then, according to the demand of performance, and also have clear cut, to increase the use of water resistant properties of high barrier coating of PVA.
