Why does the inner layer of aluminum foil bag use CPP instead of PE?

　　The selection of materials is determined by the final use, the contents of the package, the post-processing technology, the use of environmental conditions and other aspects. It is also an aluminum foil bag, such as packaging pickles with pickles. The inner layer data is PE, because pickles contain a certain amount of liquid, and the storage condition is about 0 ℃, so PE is suitable for use. If you cook food like meat, you will choose CPP. There is also packaged milk powder, and the inner layer also uses PE. Consider the requirements of pollution resistance and impact resistance. Meat products are packaged, but they do not need high temperature cooking. CPP quality is poor when stored at 0~4 ℃.

　　CPP becomes brittle when the temperature is lower than 10 degrees. PE has good low temperature resistance, but it may become soft when the temperature is higher than 65 ℃. It is recommended to select modified heat sealing materials according to the use conditions.

　　Quality is the life of an enterprise, and promise is the soul of an enterprise. The company has always adhered to the operation concept of integrity, innovation, quality as the root and scientific management, and has been committed to the development and discussion of new technologies and products for a long time. Based on the principle of pragmatism, innovation and integrity, the company has produced general packaging products, vacuum products, high-temperature cooking products, single and double side stretch film products, etc. with its excellent functions, appropriate price, reliable quality The business promise of integrity is widely praised by new and old customers.
