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 ℃. The commonly used materials are generally Nyon NY composite cooking grade CPP (RCPP), and Nyon NY composite pure aluminum AL composite cooking grade CPP (RCPP).

RCPP is a cooking CPP film. It has better heat resistance than ordinary CPP film and can withstand 121 ℃ and higher temperatures. RCPP can be used for some bags that require sterilization at a temperature above 121 ℃.

High-temperature cooking bag is a plastic that can withstand high temperature cooking and has high barrier performance. Today, we are introducing another common high-temperature resistant material, which plays an important role in the plastic packaging material industry, especially in the food packaging industry. This material can withstand high temperature cooking and has high barrier performance. The film made of it has been widely used in China, and Z is known as ham sausage casing. This material is called PVDC.

PVDC multilayer co-extruded composite film is mainly used in the packaging field with strict restrictions and requirements on oxygen and water vapor transmission, such as:

1. The packaging of various cooked meat products (vacuum bag, heating stretch molding package, inert gas bag) can be stored at room temperature for more than one month.

2. It is used for aseptic packaging of fresh milk. It is stored at normal temperature and has a shelf life of 3 months.

3. Instead of using aseptic packaging machine, ordinary liquid packaging machine is used for filling, and the packaging of secondary sterilization of various fresh milk is used. The shelf life can reach more than 1 month under normal temperature.

4. Concentrated fruit juice, jam and vacuum aseptic packaging for long-term storage.

5. The vacuum preservation small package and inflatable preservation small package of fresh livestock and poultry meat can be stored for half a month at room temperature.

6. Packaging of various condiments with unique flavor.

7. Food packaging that contains high protein, high fat, has fragrant, crisp, swelling and crisp properties, and is not allowed to have a little oxidative deterioration and a little hygroscopic deliquescence during storage and circulation, such as high-grade baked food, coffee, cereal, fried food, especially fried fruit, etc.

8. Packaging of purified water, especially purified 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 those that cannot be rust-proof with oil stored at sea and in coastal areas.

L2. Packaging of chemical products and pesticides.

L3. It is compounded with paper and cloth to make packaging with special performance and can be used in special occasions. In short, different high-temperature cooking materials are widely used. They are generally made by composite process. The appearance of different high-temperature cooking materials will improve the packaging quality level to a new stage. What we have done is to apply these high-temperature cooking materials to the extreme and bring better packaging solutions for the majority of users!
