What material is the steaming bag made of? How many categories are there?

Steaming bag is a type of food packaging bag that can be heated, also known as a "soft can". Food packaged in steaming and boiling bags does not require refrigeration or freezing, has a stable shelf life, and can be comparable to metal cans. Due to the lower price of the composite film used to manufacture steaming and boiling bags compared to metal plates, the price of steaming and boiling bags is lower, greatly reducing packaging costs. Therefore, steaming bags are widely used in the food industry. So what material is the steaming bag made of? How many categories are there?
What material is the steaming bag made of? Steaming bags are often made of three layers of composite materials. The representative structure of steaming bags is: the outer layer is made of polyester film for reinforcement; The middle layer is made of aluminum foil, which is used for light, moisture, and gas leakage prevention; The inner layer is made of polyolefin film (such as polypropylene film), used for heat sealing and contact with food. Steaming bags are lightweight and can be stacked for storage, occupying less space. After packaging food, they occupy less space than metal cans, making full use of storage and transportation space and saving storage and transportation costs.
 
What are the types of steaming bags? Steaming bags can be divided into four categories, such as high-temperature steaming type, metalized type, universal type, and steaming type. Among them, the high-temperature cooking type requires three-layer copolymer CPP film, the metalized type requires aluminum foil bags, the universal type requires multi-layer co extruded cast film, and the cooking type requires two-layer copolymer CPP film. These four types of steaming bags each have their own advantages and applicable scope, and can be selected according to needs.
 
How much does the steaming bag tolerate? Steaming bags have the advantages of both canned containers and plastic bags that are resistant to boiling water. Food can be kept intact in the bag, heated at 120-135 ℃, and taken out for consumption. Suitable packaging for meat and soy products, convenient, hygienic, and practical, and can maintain the original flavor of the food well, which is favored by consumers.
 
How long can a steaming bag be steamed for? Due to its thinness, steaming bags can quickly reach the predetermined temperature when heated, thus consuming 30-40% less energy than iron cans. The heating time can be adjusted appropriately according to different processing requirements.
