A wide range of plastic raw materials, food bottle
Plastics used in food packaging in China is also up to 15, six, such as PE, PP, PS, PET, PA, PVDC, EVA, PVA, EVOH, PVC, ionic bonding resin. Which there is high resistance of oxygen PVA, EVOH, PVDC, PET, PA and so on, there is high resistance wet PVDC, PP, PE, etc.; resistance-ray irradiation, such as PS aromatic nylon, etc.; resistance to low temperature, such as PE, EVA, POET, PA, etc.; resistance and mechanical properties of a good oil, such as ionic resins, PA, PET, etc., that is also resistant to low-temperature heat sterilization, such as PET, PA and so on. Monomer molecular structure of various plastics are different degree of polymerization of different types and quantities of additives different properties are different, even if the same kinds of plastic there will be differences in the nature of the different brands. Therefore, we must, upon request the appropriate choice of plastic or a combination of plastic and other materials, choose the wrong foods may cause the quality of reduction or even loss of food value. For example, the Northeast in a certain place instead of using PVC plastic corrugated boxes corrugated packaging apples, because the PVC barrier carbon dioxide, oxygen, water, non-performance is far greater than the carton of the gas barrier and moisture barrier, so that Apple can not maintain a certain degree of breathing, leading to a large number of rot.
