What are the materials of high temperature cooking bags

As we all know, the high temperature cooking bag can withstand the temperature of 121-135 degrees. The more commonly used materials are generally Ninong NY composite cooking grade CPP or RCPP, and Ninong NY composite pure aluminum AL composite cooking grade CPP or RCPP. RCPP is a retort CPP membrane. It has better heat resistance than ordinary CPP film and can withstand temperatures of 121 degrees and higher. For some bags that need to be sterilized at temperatures above 121 degrees, RCPP can be used. High-temperature cooking bags are plastics that can withstand high-temperature cooking and have high barrier properties. Today, YLTpacking plastic bags will introduce to you another relatively common high temperature resistant material, which occupies an important position in the plastic packaging material industry, especially the food packaging industry. This material can withstand high temperature cooking and has high barrier properties. The film made with it has been widely used in China, and the most well-known is the ham casing. This material is called PVDC. PVDC multi-layer co-extruded composite film is mainly used in packaging fields with strict restrictions and requirements on oxygen and water vapor transmission, such as: 1. Packaging of various cooked meat products (vacuum bagging, heat-stretching packaging, inert filling Gas bags), the shelf life of storage at room temperature can reach more than one month. 2. It is used for aseptic packaging of fresh milk, stored at room temperature, and the shelf life is 3 months. 3. Do not use aseptic packaging machine, but use ordinary liquid packaging machine for filling, and use secondary sterilization for packaging of various fresh milk, which can achieve a shelf life of more than 1 month at room temperature. 4. Long-term storage of concentrated juice, jam, vacuum aseptic packaging. 5. The vacuum fresh-keeping small package of fresh livestock and poultry meat, the inflatable fresh-keeping small package, can be stored at room temperature for half a month. 6. Packaging of various condiments with unique fragrance. 7. Food packaging that contains high protein and high fat, has fragrant, crisp, puffy and brittle properties, does not allow a little oxidative deterioration and does not allow a little hygroscopic deliquescence during storage and circulation, such as advanced baked goods, coffee, Cereals, fried foods, especially fried fruits, etc. 8. Packaging of pure water, especially pure water for field operations and field operations. 9. Drug packaging. 10. Packaging of cosmetics. 11. Packaging of precision industrial products such as machinery and electronics, especially the packaging of products that cannot be rust-proofed with oil and stored in offshore and coastal areas. l2. Packaging of chemical products and pesticides. l3. It is compounded with paper and cloth to make packaging with special properties and applied in special occasions. In short, different high-temperature cooking materials are widely used, and they are generally made by composite technology. The emergence of different high-temperature cooking materials will raise the level of packaging quality to a new level. What we do is to apply these high-temperature cooking materials to the extreme and bring better packaging bag solutions to the majority of users!
