Performance Index Of Protective Film
- Jul 16, 2018 -

Viscosity is peel strength, which is a performance index for protecting the bond strength of film. It is also an important index to decide the price of protective film. The viscosity of protective film is usually divided into micro viscosity, low viscosity, medium low viscosity, medium viscosity, medium high viscosity, high viscosity, super high viscosity.

The thickness of the protective film includes the thickness of the substrate and the thickness of the glue, and the protective films with different thickness usually have different prices.

The material of protective film includes PET, PE, PVC, CPP, OPP, BOPP and so on.

The tensile strength is the maximum tensile stress in the tensile test, which is called tensile strength in the academic circle. The tensile strength is often called in the engineering application, and the result is expressed in MPa.

Temperature resistance is an important performance index of protective film. Generally, the temperature resistance of PE is worse than that of PET, CPP has high temperature resistance and OPP is not resistant to high temperature.

The protective film has glue, oil glue, acrylic adhesive and so on.

These performance indexes are the main factors determining the price of protective film.
