Freezing film is a type of plastic film specifically used for packaging frozen food, usually made with special materials and processes to ensure good physical and protective properties under low temperature conditions. This type of film is very common in the food industry because they can effectively protect food from freezing burns, spoilage, and other issues during the freezing process.

Freezing film usually has the following characteristics:

Low temperature adaptability: Freezing film can maintain good flexibility and strength at extremely low temperatures, and is not easily brittle or broken, ensuring the integrity of packaged food.

Cold resistance: Cryogenic film materials usually have good cold resistance, and will not deform or break even after prolonged exposure to extremely low temperatures.

Sealing performance: Freezing film can effectively seal food, prevent the entry of air, water vapor and other substances during the freezing process, and maintain the freshness and taste of food.

Tensile strength: Cryogenic film has high tensile strength, which can withstand the tensile force that may be applied during the freezing process and is not easily broken.

Transparency: Cryogenic films usually have high transparency, which can clearly display the appearance of packaged food and enhance the attractiveness and competitiveness of the product.

Food safety: High quality frozen films are usually made from raw materials and production processes that meet food safety standards, ensuring the safety and hygiene of packaged food.
