Introduction of PET protective film use and protective performance
What is PET protective film
PET protective film, the full name of Polyethylene, is the simplest polymer organic compound in the world today, and it is also the most widely used polymer material. PE protective film is based on special polyethylene (PE) plastic film, which is divided into high density polyethylene protective film, medium density polyethylene and low density polyethylene according to the density.
The biggest advantage of PET protective film is that the protected product will not be polluted, corroded, scratched during production, processing, transportation, storage and use, and can protect the original smooth and bright surface, thereby improving product quality and market. Competitiveness.
The use of PET protective film
1. Hardware industry: computer case, galvanized sheet stamping, aluminum sheet, stainless steel sheet, titanium gold sheet, plastic steel sheet, glass sheet, solar panel, etc.;
2. Optoelectronic industry: LCD liquid crystal display, backlight panel, cold light film, membrane switch, mobile phone screen, etc.;
3. Plastic industry: ABS, PP injection molding products, PVC sheets, acrylic sheets, instruments, plastic lenses, surface protection of painted parts, etc.;
4. Printing industry: PVC, PC board, aluminum plate, film and other printed nameplate surface protection, etc.;
5. Wire and cable industry: the protection of vertical copper wires, semi-finished products, finished products and rolled products can effectively prevent dust pollution, and has anti-oxidation and anti-fouling effects;
6. In the electronics industry, it is usually necessary to protect finished and semi-finished products from production, and it is not easy to produce scratches and bumps on the assembly line;
7. In the mobile phone digital industry, mobile phone film, also known as mobile phone beauty film and mobile phone protective film, is a cold-proof film that can be used to protect the phone body and screen.
PET protective film viscosity analysis
PE protective film can effectively protect its products from scratches and contamination during storage and transportation during use. PE protective film can effectively protect the original smooth and beautiful surface of its products. To a certain extent, improve the quality of its products.
The PET protective film can effectively have a certain adhesion performance to the material, so that the material will not fall and lift during handling and processing, and the product also has a certain retention force, weather resistance stability, resistance, etc.
The viscosity of the PET protective film is very suitable, it is very easy to stick and tear, and the increase in peeling ability after time changes during use is as small as possible. In direct sunlight, one year is ok even if it is used for a long time.
How to protect PET protective film
When using PET protective film, the problem most reported by users is product degumming. After the user installs the profile, the user needs to tear off the product from the surface of the profile. The viscosity of the protective surface does not follow the protective film, but remains on the product of the profile.
This situation is the last thing users want to see, mainly because it is cumbersome and it is time-consuming and laborious to ask their professionals to scrape the glue off the profile. The biggest reason for this problem may be that the pressure-sensitive adhesive used in the product does not meet the regulations, which will cause the PET protective film product to be peeled off during the peeling process. Since its external tension is greater than its internal stress, it will remain directly on the contour. If users encounter such problems, they can directly wipe with a clean cloth dipped in a little alcohol.
Society is developing, human beings are progressing, people’s requirements for the quality of life are constantly improving, and various new things are constantly emerging. This looks very ordinary, but it also brings great convenience to our lives.
In the past, some issues have arisen in the packaging and shipping of certain products. In the past, many of our products experienced frequent problems in transit, the most common being wear and tear. The economic loss caused by this is very large. Once certain items are worn, they are basically useless.
At the same time, the production process of PET protective film is also constantly improving, and our scope of use is also expanding, so the precision of the machines we produce is also improving.
