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.https://www.pe-protectionfilm.com/
