How to better choose protective film

The demand for protective films is very high, and manufacturers are a mixed bag in terms of technology and product quality. If you don’t know some techniques for selecting protective films, it will be difficult to avoid being deceived.
Only products with the following characteristics are products that users can buy with confidence:
1. Stable performance. After purchasing products from many manufacturers, they cannot be used immediately and need to be stored in warehouses. Some warehouses do not even have light-closing conditions, requiring the products to remain stable even if they are stored without light for a long time. It has stable performance, will not change its properties, and can still be used normally.
2. Easier construction When the protective film is applied, it should be easy to construct. Even if it is stretched to a certain extent, it will not be easily damaged. It is required to have a certain elasticity and a certain tensile strength; During the peeling process, it should also be easy to tear, without any reaction with the material being pasted, and without the glue and film detaching.
3. It will not affect the surface to be pasted. Because the protective film itself protects the pasting material, it should not have any reaction with the material itself. It will neither leave glue on the surface of the material during the glass process nor Any chemical reaction will occur with the material surface, and the surface material should have its original properties.
4. Environmental protection performance requirements of materials. With the improvement of people's awareness of environmental protection, protective films are also required to have environmental protection properties, not to emit harmful gases, and not to cause harm to the surrounding environment.
