Main products: aluminum foil bag, vacuum bag, shielding bags, aluminum bags, board vacuum bags, cooking food vacuum bag, nylon vacuum bag, anti-static bags and other packaging materials, metal. Since the main material comes to food vacuum bag vacuum packaging material, material that is essential for classification, the following are suitable for all vacuum packaging material characteristics: First, where PE for low temperature use, RCPP suitable for high temperature cooking use; two, PA is to increase physical strength, puncture resistance; three, AL foil in order to increase the barrier properties, shading; four, PET, increase the mechanical strength, stiffness of the gifted. Then according to the needs, in combination, a variety of properties, there are transparent, in order to increase the barrier properties of barrier coatings using water-PVA. Several types of vacuum complex: 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 packaging for a variety of meats cooked food, easy to use, and health. Material: NY / PE, NY / AL / RCPP, NY / PE Features: moisture, temperature, shading, aroma, robust application: high-temperature sterilization of food, ham, curry, eel, grilled fish and gravy products. Vacuum packaging currently the most used primarily film material, of course, but also the use of bottled and canned. Food vacuum packaging film material to be used, to ensure that the packaging effect, aesthetic, economic and other aspects of a variety of foods to achieve the best condition. Meanwhile, food vacuum packaging for light resistance and stability of the material also have higher requirements. When a material alone can not meet these requirements, the package will tend to a combination of a variety of different materials together.
