How high temperature can PE vacuum bags withstand?

When it comes to PE vacuum bags, people may not have a detailed understanding of them yet. Many friends may ask, what is the material abbreviation of PE vacuum bags? PE vacuum bag? How high temperature can it withstand? Don't worry for now, Jinde Packaging will give you a detailed introduction.

PE is an abbreviation for polyethylene and is a commonly used material for vacuum bags. PE vacuum bags have excellent low-temperature resistance and can be used at temperatures ranging from -100 to 70 ° C. However, they do not have the same performance and only have a learning point of 140 ° C. PE vacuum bags have good chemical stability and can withstand most acid-base corrosion. PE vacuum bags are widely used in various food, clothing, medicine, fertilizers, and industrial products. To enhance the performance of vacuum packaging bags, PE is usually compounded with packaging materials such as PA and PET to form composite vacuum bags.

The common structure and characteristics of PE vacuum bags are introduced as follows:

PA/PE vacuum bags have a soft touch and high tensile strength, but they are prone to water absorption and have poor heat sealing properties. Mainly used for food packaging.

PET/PE vacuum bag has a slightly hard feel, crisp sound, high transparency, excellent gas and oil resistance, and fragrance retention properties. It has good chemical stability and is resistant to dilute acids, alkalis, and common organic solvents.
