Precautions for selecting protective film

1. Different surfaces require different viscosity;
2. Different materials with the same similar surface may also require different viscosities;
3. The subsequent processing steps are the key to determining the viscosity. Subsequent processing generally includes bending, stamping, cutting, drilling, thermoforming, etc.;
4. Reasonable matching of thickness and viscosity;
5. The tensile strength and elongation of the protective film to ensure that the flexibility and strength of the protective film can meet the requirements;
6. The ultimate principle of protective film selection: full testing.
