What is the difference between high temperature vacuum bag and freezing vacuum bag
High temperature vacuum bags, like refrigerated vacuum bags, are also typical polyolefin polymers. The two types of vacuum bags have many things in common, such as odorless, odorless, environmental protection and other characteristics; resistance to acid, alkali, salt and a variety of compounds, stable characteristics; balance of physics and physical properties; high moisture resistance and water resistance, It has certain oxygen barrier and wear resistance; it has excellent formability and very good heat sealability. Like high-temperature vacuum bags, high-temperature vacuum bags also have the advantages of large total output, universal origin, high quality and low price.
Compared with high temperature vacuum bags and refrigerated vacuum bags, the main differences are as follows:
1. The heat resistance of high-temperature vacuum bags is much better than that of refrigerated vacuum bags. It can withstａnd high temperatures above 120°C, and high-temperature vacuum bags can even meet the requirements for high-temperature steaming above 140°C.
2. The light transmittance and compressive strength of high-temperature vacuum bags are also better than those of frozen vacuum bags. Although the wear resistance of high-temperature vacuum bags is not ideal, it is better than that of refrigerated vacuum bags.
3. Compared with refrigerated vacuum bag plastics, the key defect of high temperature vacuum bags is poor cold resistance. High temperature vacuum bag homopolymers are likely to mainly show significant ductility at 0°C.
To sum up, the difference between high-temperature vacuum bags and refrigerated vacuum bags is still very large. You can see which vacuum bags are suitable according to the packaging regulations of the product. It is not the more expensive one that is the best. Only the ones that are suitable are not suitable. It has better functions.
