When does the protective film to layer occur

The layering of protective film refers to the separation or fall off of different layers of protective film during use or storage. This phenomenon may cause the protective film to lose its protective function, reducing its appearance and performance.

Here are some situations that can cause the protective film to layer:

1. Inappropriate viscosity: If the viscosity of the protective film is inappropriate, it may lead to the separation of the layers of the film. Too weak viscosity will cause the protective film to fall off, while too strong viscosity may cause the film to tear when torn.
2. Temperature and humidity changes: Changes in temperature and humidity may affect the bonding between the layers of the protective film. In environments with large changes in temperature or humidity, the expansion and contraction of different materials can lead to the creation of gaps between layers.
3. Low-quality materials: low-quality protective film materials may be stratified during use. Unstable chemical properties or material structure may lead to separation between film layers.
4. Expired or aging: The service life of the protective film is limited, and the expired or aging film may have delamination problems. The membrane material may lose its original viscosity and stability.
5. Improper storage: The wrong storage conditions, such as exposure to extreme temperature, humidity, or sunlight, may accelerate the aging and delamination of the protective film.
6. Chemical effects: Some chemicals, such as solvents, cleaners, or other corrosive substances, may affect the interlayer bonding of the protective film, resulting in delamination problems.
7. Stress and extrusion: Long-term stress or pressure acting on the protective film, such as stacking or stacking, may lead to the layering of the protective film.
8. Manufacturing defects: there may be uneven adhesion, uneven coating, and other problems in the manufacturing process, which may lead to delamination when used.

To reduce the risk of delamination, manufacturers need to select high-quality materials, ensure proper stickiness, follow correct manufacturing and storage methods, and consider using measures such as moisture resistance and sun protection. When using the protective film, consumers should also avoid improper tearing and exposure to harsh environments to extend the service life of the protective film.
