The high-temperature-resistant retort bag is a composite plastic film bag that can be heated. It has the advantages of both canned containers and boiling water-resistant plastic bags. The food can be kept intact in the bag, sterilized and heated at high temperature (usually ~3°C), and then taken out and eaten. After more than ten years of use, it has been proven to be an ideal sales packaging container. It is suitable for packaging meat and soy products. It is convenient, hygienic and practical. It can well maintain the original flavor of food and is favored by consumers.
In order to meet the performance requirements of the retort bag, the structure of the high-temperature-resistant retort bag is made of high-strength polyester film for the outer layer, aluminum foil with light-shielding and air-tightness for the middle layer, and polypropylene film for the inner layer. There are three-layer structures:
, two types, and four-layer structures.
(Polyethylene) is a very safe chemical material, and there is absolutely no problem in using it for food preservation in bone-stick bags. In contrast, polyvinyl chloride is a polymer of a chemical substance called vinyl chloride. Vinyl chloride itself is harmful to the human body. Although its polymer polyvinyl chloride is harmless in principle, any chemical substance The polymerization is not complete, so a certain amount of vinyl chloride is not completely polymerized but cannot be separated from it. This unpolymerized vinyl chloride is the culprit of carcinogenic materials.
Both are hard plastic. In addition to being used as plastic wrap and bone bags, they also have many similar uses. Safety and long service life are the strengths of bone bag materials. From the analysis of the extraction methods of these two materials, the production cost of PTFE should be lower, because it is extracted directly from petroleum, and there is an additional processing step in the production.
