What material is the vacuum packing bag, please?
Generally composite materials, can be two kinds of material composite, or three, see the need.
Vacuum packaging material has two layers of composite, there are three layers of composite, common two layer composite more, want to see the products installed. Vacuum packaging material is divided into PET/PE PA/PE PA/CPP, PET composite can be evacuated, but relatively easy to leak, PET more brittle, PA/PE is a good vacuum performance, can withstand 100 degrees Celsius water sterilization, minus 30 degrees Celsius temperature freezing. PA/CPP is a vacuum cooking bag can withstand 120 degrees Celsius temperature cooking, minus 30 degrees Celsius temperature freezing. According to the customer installed products, the choice of material is not the same, can be customized according to customer requirements.
Vacuum packaging is a general term for flexible packaging composite membrane products. If the temperature is different, there will be a lot of division: there is less than 100 bactericidal, and some need 100 degrees of sterilization, and 121 degrees and 135 degrees. Of course, there is also room temperature, the choice of this temperature under the condition of the sterilization method is irradiation sterilization. And also consider the content and weight of the package to determine the reasonable use of the packaging materials. There is no static, and the right is the best.
