Now, with the continuous development of society and the progress of mankind, people's requirements for their daily quality are also constantly improving, the production process of PE protective film is constantly improving, the scale of our application is also constantly increasing, and the application requirements are constantly showing all kinds of new things. Although it looks relatively general, it also brings great convenience to our days.
PE protective film is easy to stick and tear during application, with small change over time, and the rise of stripping force is becoming smaller and smaller. Under the condition of sunlight exposure, the application period of the whole product is as long as half a year to one year, and there will be no pollution and corrosion in the process of application.
The mechanical function of PE protective film is very suitable for the tensile strength, elastic modulus and elongation required by its users. The protective film is lazy to the appearance of the data to be maintained, and has excellent adhesion function to the data to be maintained. During the data transfer and processing, the maintenance film will not rise and fall.
PE protective film has good weather resistance and adhesion stability. After several days or long sticking, the peeling force does not increase significantly, and it is easy to remove. When it is removed, there is no residual glue left on the protected surface and no photo.
After being used for a period of time, the PE protective film will perform well in the center, but its two ends are cocked up. The primary reason for this phenomenon is that the protective mold has a large degree of stretching in the posting process of the maintained profile. In the future, it will show unnecessary retraction in case of high temperature environment.
The problem of PE protective film mostly appears on the products of customers in the south. Therefore, during the production process of PE protective film, we should pay attention to the impact of environmental temperature difference on the application of products and avoid unnecessary appearance stretching in the posting process.
