Adhesive requirements for PE protective film and its protective effect on products

What is PET protective film

PE protective film, also known as Polyethylene, is the simplest structured polymer organic compound and the most widely used polymer material in the world today. PE protective film is made of special polyethylene (PE) plastic film as the substrate, and is divided into high-density polyethylene protective film, medium density polyethylene, and low-density polyethylene according to different densities.

The biggest advantage of PE protective film is that the protected product is not contaminated, corroded, scratched during production, transportation, storage, and use, protecting the original smooth and shiny surface, thereby improving the quality and market competitiveness of the product.

The use of PET protective film

1. Hardware industry: computer cases, galvanized sheet stamping, aluminum plates, stainless steel plates, titanium plates, plastic steel plates, glass plates, solar panels, etc;

2. Optoelectronic industry: LCD displays, backlight panels, cold light chips, film switches, mobile phone screens, etc;

3. Plastic industry: ABS, PP injection molded products, PVC sheets, acrylic sheets, instruments, plastic lenses, surface protection of painted parts, etc;

4. Printing industry: surface protection of printed nameplates such as PVC, PC board, aluminum board, film, etc;

5. Wire and cable industry: The protection of shaft mounted copper wire, semi-finished products, finished products, and rolled products can effectively prevent dust pollution and have anti oxidation and anti dirt effects;

In the electronics industry, finished and semi-finished products are generally protected during production to prevent scratches and damages on the assembly line;

7. In the mobile phone digital industry, mobile phone film, also known as mobile phone beauty film or mobile phone protective film, is a type of cold watch film that can be used to install the body and screen of a mobile phone.

Adhesive analysis of PET protective film

PE protective film can effectively protect its products from scratches and contamination during storage and transportation. PE protective film can effectively protect the original smooth and beautiful surface of its products, which can improve the quality of its products to a certain extent.

The operation of PE protective film can effectively provide certain adhesion properties to the material, so that the material will not fall off or curl during handling and processing. The product also has certain adhesion stability and weather resistance

The viscosity of PE protective film is very suitable, and it is easy to stick and tear. The smaller the increase in its peeling ability over time during use, the better. Even if the product is used for up to a year under sunlight exposure, it can still be used.

How to protect the performance of PET protective film

The most common problem reported by users when using PE protective film is the detachment of the product. After installing the profile, users need to tear off the product from the surface of the profile, and the adhesion of the protective surface does not follow the protective film, but remains on the product of the profile.

This situation is the last thing that users want to see, mainly because it is quite troublesome and requires professional staff to scrape off the glue from the profile, which is very time-consuming and labor-intensive. The biggest reason for this problem may be that the pressure glue used in the product does not meet the regulations. This will cause the PE protective film product to remain directly on the profile during the peeling process due to its external tension being greater than its internal stress. If users encounter such problems, they can directly use a clean cloth dipped in a small amount of alcohol to wipe it off.

Society is developing, humanity is progressing, and people's demands for quality of life are constantly increasing. Various new things are also emerging. This may seem ordinary, but it has also brought great convenience to our lives.

In the past, many of our products often encountered problems during packaging and transportation, the most common of which was wear and tear, resulting in significant economic losses. Because some items, once worn out, are basically useless.

In traditional packaging, the quantities used in our food and medical industries are very large. The use of packaging in the past has caused significant environmental pollution.

Meanwhile, the production process of PE protective film is constantly improving, and the scope of our use is also expanding.
