PE protective film has low viscosity, medium viscosity, high viscosity and extra high viscosity. Many people who choose PE protective film do not know how to choose a protective film that suits their viscosity, so let's introduce it to you today!
First of all, we need to know that the surface of different products require different viscosities of the protective film. We need to understand the characteristics and appearance of the raw materials of the product to be adhered: such as steel, aluminum, plastic, glass, etc.; whether the product has a coating and which coating Layer, roughness of appearance, etc. There are also processes for subsequent processing of products: such as stamping, cutting, bending, punching, etc.
Followed by other requirements: its operating environment, storage and transportation conditions, substrate color, printing or not.
