4 suggestions for buying high-quality protective film

In recent years, with the continuous development of e-commerce and logistics industry, new things have appeared constantly, greatly improving people's quality of life. However, some products often have some wear problems during packaging and transportation, which affects the product quality and causes huge economic losses. In recent years, protective film has been widely used with its own significant advantages, and has been well received in the packaging and transportation industries. The protective film can effectively protect the product from pollution, corrosion and scratches during production, processing, transportation, storage and use, protect the original smoothness and gloss of the surface, and significantly improve the quality and market competitiveness of the product . Therefore, the current market demand is also increasing. Today, let us talk about 4 points to be aware of during the purchase process:

1. Check the light transmittance, choose products with better light transmittance, you can use professional optical instruments to measure, but if there is no professional instrument, you can also cut a small piece of film and place it on the computer desktop, and then observe The brightness of the computer Word document in the area without film, and compare and choose the brighter

2. Usually look at the haze, the smaller the haze, the better the material, and vice versa. By pasting the film on the closed computer display, we can observe and compare the screens. The clearer the color, the better the haze. If you are in a darker room, you can also turn on the fluorescent light, place the film between your eyes and the light, and observe whether the mist is evenly distributed in the mist layer. The more serious, the greater the haze;

3. The LCD screen is a sensitive device for static electricity, and the antistatic effect is very important. We can judge whether the product can absorb some paper scraps or soot. The stronger the adsorption force, the higher the static electricity generated by the material, and the worse the material, so it is not recommended;

4. Whether it is scratch-resistant, scratch-resistant and scratch-resistant is also a very important aspect. When buying, we can use slightly harder equipment or nails in the film. The above is to use the strength of an ordinary stylus to scratch to determine its anti-scratch function.
