Selection requirements for protective film

- Sep 16, 2020-

1. Different surfaces require different stickiness;

2. Different materials on the same similar surface may also require different viscosities;

3. The subsequent processing steps are the key to determining the viscosity. Follow-up processing generally includes bending, stamping, cutting, drilling, thermoforming, etc.;

4. Reasonable combination 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 principle of protective film selection: fully test.
