High Temperature Cooking Packaging Bags are composite plastic film bags that can withstand high-temperature cooking. They have the advantages of both canned containers and boiling water-resistant plastic bags, so they are also called "soft cans". This type of packaging bag is usually used for foods that require high-temperature sterilization. It can maintain stability in high-temperature environments to ensure the safety and hygiene of food.

Materials and manufacturing processes

The materials of high-temperature cooking packaging bags are varied, including polyester film, aluminum foil and polyolefin film (such as polypropylene film). These materials are combined together through a composite process to form packaging bags with excellent barrier properties, high-temperature cooking resistance, grease resistance and chemical corrosion resistance. For example:

Polyester film: As the outer layer, it has high mechanical strength and weather resistance, and has good printing performance.

‌Aluminum foil: Located in the middle layer, it has excellent barrier properties and thermal conductivity, and can effectively prevent the influence of light, oxygen and moisture on food.

‌Polyolefin film: As the inner layer, it directly contacts the food and has good heat sealing and grease resistance.

Application scenarios

High-temperature cooking packaging bags are widely used in various foods that require high-temperature sterilization, including:

‌Cooked food, soy products, meat‌: Such as cooked meat products, soy products, etc., the shelf life can reach more than one month at room temperature.

‌Condiments, sauces‌: Such as various condiments and sauces, which are easy to store and transport at room temperature.

‌Fresh milk‌: Used for aseptic packaging of fresh milk, with a shelf life of up to 3 months at room temperature.

‌Juice, jam‌: Used for vacuum aseptic packaging of concentrated juice and jam.

‌Fresh livestock and poultry meat‌: Used for small vacuum fresh-keeping packages, which can be stored at room temperature for up to half a month.

‌Purified water‌: Especially purified water for field operations and field operations.
