Different surfaces require different stickiness;
Similarly similar surfaces of different materials may also require different stickiness;
Subsequent machining steps are the key to determining stickiness. Subsequent processing generally have bending, stamping, cutting, drilling, thermoforming, etc.
The reasonable collocation of thickness and viscosity;
The tensile strength and elongation of the protective film to ensure the flexibility and strength of the protective film can meet the requirements;
The ultimate principle of protective film selection: Full Test.
Understanding the characteristics of pasted materials
Materials: such as steel, aluminum, plastic, glass and so on.
Surface properties: If there is coating, which coating, surface roughness, etc.
Follow-up processing technology: such as stamping, cutting, bending, punching and so on.
Other requirements: The use of environment, storage and transportation conditions, outdoor requirements, base material color, printing or not.
