Manufacturer of China stretch film tells you the features of stretch film

The main features

Most stretch films are light in quality and stable in chemistry, and will not rust. Vacuum stretch film has good impact resistance; Torque stretch film has good transparency and abrasion resistance. Superior insulation and low thermal conductivity; Two-way stretch film generally has good formability, good coloring quality and low processing cost. Most stretch film with low heat resistance, high thermal expansion rate, easy to burn; The tool has poor dimensional stability and is easy to deform. Most stretch film  have poor tolerance to low temperatures and become brittle at low temperatures. It is easy to get old; Some stretch films are soluble in solvents.

Stretch film can be divided into two types: thermosetting and thermoplastic, the former can not be re-shaped and used, and the latter can be re-produced. Thermal plasticity has a high physical elongation rate, generally between 50% and 50%. The force is not completely linear at different elongation rates. For r&d institutions or enterprises of stretch film, there is a plastic tensile testing machine of European standard instruments [1].

Different properties of stretch film determine its application in industry. With the development of technology, the modification of stretch film has not stopped studying. Hopefully in the near future, stretch film can be modified to be more widely used, even replacing materials like steel and no longer polluting the environment.
