What is the difference between high-temperature steaming bags and vacuum bags?

Both high-temperature steaming bags and vacuum bags have the characteristics of being soft and lightweight, and the packaged food has a longer shelf life when stored at room temperature. Moreover, transportation, storage, and sales are very convenient, making them very suitable for the consumption needs of modern society. So what is the difference between high-temperature steaming bags and vacuum bags?
High temperature steaming bag: It 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 literal meaning of a high temperature steaming bag is to put it on a pot for high temperature steaming, but the steaming temperature should be controlled within 135-121 degrees Celsius, and the steaming time should be between 30-40 degrees Celsius. Commonly used materials include nylon NY composite steaming grade CPP and RCPP, as well as nylon NY composite pure aluminum AL composite steaming grade CPP and RCPP. There are two types of high-temperature cooking bags, one is transparent and the other is opaque. The opaque cooking bag has an additional layer of aluminum foil compared to the transparent cooking bag. The material of the cooking aluminum foil bag is: pet+al+cpp \ ny+al+cpp, and the other material is pet+cpp/bopa+pe. The thickness depends on the requirements, and the bag styles include three edge sealing, middle sealing, sealed, self sealing, etc.
 
Vacuum bag: also known as close fitting moisture-proof bag, aluminum foil bag, aluminum-plastic composite bag, its material is generally PET/AL/CPE or PET/NY/AL/CPE. It has good oxygen isolation, shielding, moisture resistance, light shielding functions, and excellent heat sealing properties. Vacuum bags are generally divided into PA/PE or PA/RCPP; PET/PE or PET/RCPP. Usually used as food vacuum bags, pharmaceutical vacuum bags, electronic vacuum bags, high-temperature vacuum bags, low-temperature vacuum bags, etc.
