Main products: aluminum foil bag, vacuum bag, shielding bags, aluminum bags, board vacuum bags, cooking food vacuum bag, nylon vacuum bag, anti-static metal bags and other packaging materials. The main material Since talking about food vacuum bag vacuum packaging material, that is the essential material classification, the following are suitable for all vacuum packaging material characteristics: First, where PE for low temperature use, RCPP for high temperature cooking use; two, PA is to increase physical strength, puncture resistance; Third, AL is to increase the barrier properties of aluminum foil, shading; Fourth, PET, to increase the mechanical strength, excellent stiff. Then according to demand, in combination, a variety of properties, but also transparency, the use of water in order to increase the barrier properties of PVA barrier coating. Several composite vacuum bag Type: generally: PA / PE or PA / RCPP PET / PE or PET / RCPP have three, four, in order to increase the texture of the material properties: PET / PA / PE PET / AL / RCPP PA / AL / RCPP PET / PA / AL / RCPP several common characteristics of high-temperature vacuum bag cooking bag, vacuum bag used to package a variety of meat cooked food, easy to use, and health. Material: NY / PE, NY / AL / RCPP, NY / PE Features: moisture, temperature, shading, Paul Hong, tough application: high temperature sterilization of food, ham, curry, eel, grilled fish and gravy products. Vacuum packaging currently used by most major film material is, of course, but also the use of bottled and canned. Food vacuum packaging film material to be used, to ensure that their packaging effect, aesthetic, economic and other aspects of various foods to achieve the best state. Meanwhile, food vacuum packaging for light resistance and stability of the materials also have higher requirements. When a material alone can not meet these requirements, it is often a combination package from a variety of different materials together.
