Now that society is developing and human beings are progressing, its people's requirements for their quality of life are also constantly improving, the production process of PE protective film is constantly improving, and the scope of our use is also increasing. A variety of new things are constantly appearing, although they seem relatively common, they also bring great convenience to our lives.
PE protective film has excellent characteristics:
PE protective film is easy to stick and tear during use, with little change over time, and the increase in peeling force is getting smaller and smaller. The whole product can be used for half a year to one year under the condition of sunlight exposure. There will be no pollution and corrosion.
PE protective film has excellent mechanical properties, and it is very suitable for the tensile strength, elastic modulus, elongation and so on required by its users. The protective film is inert to the surface of the protected material and has good adhesion to the protected material. During the material handling and processing, the protective film will not warp or fall off.
PE protective film has good weather resistance and adhesion stability. After a few days or a long time, the peeling force does not increase significantly, and it is easy to peel off. When peeling off, there is no residual adhesive on the protected surface, and no photo is left.
The PE protective film performs well in the middle after using it for a period of time, but its two ends are warped. The main reason for this phenomenon is that the protective mold is stretched to a large extent during the pasting process of the protected profile. , In case of high temperature environment, unnecessary retraction occurred.
The problem of PE protective film mostly occurs on the products of southern customers. Therefore, during the production process of PE protective film, attention should be paid to the influence of environmental temperature difference on the use of products, and unnecessary surface stretching should be avoided during the pasting process.
