First of all, it needs to be clear that the high temperature resistance and cooking temperature of the high-temperature cooking packaging bag mentioned here cannot exceed 121 degrees Celsius. Otherwise, it will not only fail to disinfect and preserve the goods, but also seriously affect the quality of the goods. In the actual production process, we have had various problems such as damage and embrittlement of customers' packaging bags. In the final analysis, we found that it was because we did not operate according to the specified temperature and humidity in the process of using high-temperature cooking packaging bags, resulting in various quality problems and heavy losses after the goods were sold on the market.

CPP film in high temperature cooking bag is one of the important raw materials of high temperature cooking bag. CPP film has the characteristics of good transparency, high gloss, good stiffness, good moisture resistance, excellent heat resistance and easy heat sealing. In the production process of composite plastic packaging bags, CPP film is printed and compounded with other materials before making bags. The finished products meet the relevant requirements of high-temperature cooking packaging bags. It is suitable for making plastic packaging bags in many fields such as food and drugs. It is very convenient.

At the same time, the transparency of this packaging material is very good. The outer packaging bags of some commodities need to open transparent windows to show some of the appearance of commodities and increase the attractiveness of commodities.
