The self-adhesive protective film is a new type of packaging material, which is characterized by a simple production process, and can be manually wrapped or mechanically packaged using a film, and is easy to operate. Since the self-adhesive protective film is self-adhesive and does not require an adhesive film, it does not contain any chemical solvents, is environmentally friendly, does not produce any toxic gases, effectively reduces bad products, and increases product value.
Self-adhesive protective film mainly depends on electrostatic adsorption of the product itself to protect the adhered articles. It is generally used for surfaces that are sensitive to adhesives or glue residues, such as glass, lenses, high-gloss plastic surfaces, acrylics, and other very smooth surfaces. .
As a qualified self-adhesive protective film, it should have good physical properties and chemical properties, so that it has fewer crystal points, good ductility, waterproof, dustproof, high transparency, excellent temperature resistance, non-toxic and tasteless, safe and environmentally friendly. This can be widely used in hardware products, plastic products, optoelectronic products and so on.
The quality of the self-adhesive protective film is related to the standard, first of all its strength and toughness is better, that is, the film can withstand the impact of injection of emery to 6 to 8 kilograms, otherwise it will break through the protective film to break the object being processed. At the same time, it must have proper tackiness, which can not only adhere to and be firmly adhered to the product to be protected, but also can successfully remove the protective film after the processing is completed, so as not to increase unnecessary trouble due to brittle thin cracking and shredding.
Secondly, the self-adhesive protective film can not be debonded. When the protective film is peeled off, the surface of the processed product can not leave a little glue and marks to keep the product clean and beautiful. This requires that the self-adhesive protective film is inert to the surface of the material to be protected and has good adhesion properties. During the handling and processing of the material, the protective film will not warp or fall off.
In addition, the self-adhesive protective film also has good weatherability and stability of holding power. After a few days or a long time, the peeling force does not increase significantly, and it is easy to peel off. When the peeled protective film is removed, no residual glue remains on the protected surface. No picture. Not only that, self-adhesive protective film to achieve low crystal standards.
