Q&A: How high temperature can sealing film withstand?

We all know that sealing film can withstand high temperatures, but the specific high-temperature resistance varies depending on the material. Today, Leadmens Packaging will introduce it in detail for you. 

The high temperature resistance of sealing film mainly depends on its material. The common sealing film materials on the market currently include polyethylene, polypropylene, polyester, and polyamide. These materials have different high-temperature resistance characteristics. 

1. Polyethylene sealing film: The temperature resistance range of polyethylene sealing film is generally between 60 ℃ and 80 ℃. This material has good flexibility and sealing effect at low temperatures, but its performance gradually decreases with increasing temperature. 

2. Polyester sealing film: Polyester sealing film has a high temperature resistance range, generally between 120 ℃ and 180 ℃. This material can maintain good stability and sealing effect at high temperatures, making it suitable for packaging applications that require high-temperature treatment.

3. Polyamide sealing film: Polyamide sealing film has superior high temperature resistance and can withstand temperatures up to 150 ℃. This allows it to maintain good sealing performance even in extreme high temperature environments. 

In short, the high temperature resistance of sealing film varies depending on the material, and users should fully consider its high temperature resistance range and actual needs when selecting and using it to ensure the sealing effect and product quality.
