Different adhesion of PE self-adhesive protective film and its use requirements
- Aug 20, 2018 -

PE self-adhesive protective film can be classified into six types: ultra low viscosity, low viscosity, medium low viscosity, medium viscosity, high viscosity and super high viscosity. Moreover, different viscosities correspond to different protective film parameters, so it is necessary to make a correct judgment according to actual conditions and usage requirements, in order to have a correct selection result.

 

There is also a PE self-adhesive electrostatic protective film in the PE self-adhesive protective film, and this is also a common and commonly used type. This kind of protective film, which is not coated on the upper surface, is electrostatically applied to achieve the adsorption effect. In the material of the substrate, most of the materials are made of PE.

 

PE self-adhesive protective film requirements:

It has a suitable viscosity and is easy to adhere and tear away, and the protective film does not remain after being peeled off. Its weather resistance is good, even if it is exposed to the sun, it will not have a great impact on the service life of the product. In addition, the product will not be contaminated and corroded and any chemical reactions will occur during storage. In storage time, if you do not use it, you can store it for more than one year.

 

PE self-adhesive protective film wants to achieve electrostatic adsorption, and can be corona treated during the film making process to increase the surface area and electrostatic charge of the film, so as to smoothly carry out subsequent processing. If there is no glue on the film, the inner layer of the film is made of EVA, which itself has the function of adsorption, which can be obtained by a multilayer blown film casting machine.
