PE protective film performance index

There are many common PE protective films on the market. According to the viscosity of the material, they are mainly divided into: ultra-low viscosity protective film, low-viscosity protective film, midsole adhesive, medium-adhesive, high-adhesive, ultra-high-adhesive protective film. Introduce the viscosity standard of PE protective film and the use of various adhesive protective films.

PE protective film performance index

1. Ultra-low viscosity protective film (ie micro-bottom adhesion):

Characteristics: Thickness (≥0.03m±0.003), width (≤1.3), height (100-1500), substrate (PE), peel strength (≤5g/cm), temperature resistance (60), elongation (> 400)

Uses: easy to use, easy to paste and tear, no residual glue, suitable for organic sheet, instrumentation, display screen, glass lens, plastic lens, etc.

2. Low viscosity protective film

Characteristics: Thickness (≥0.03m±0.003), width (≤1.3), height (100-1000), base material (PE), peel strength (10-20g/cm), temperature resistance (60), elongation ( >400)

Uses: Stable adhesion, good adhesion, good peeling performance, no residual glue phenomenon, suitable for steel mirror plate, titanium metal, glossy plastic plate, silk screen, nameplate, etc.

3. Medium and low viscosity protective film

Characteristics: Thickness (≥0.03m±0.003), width (≤1.3), height (100-1000), base material (PE), peel strength (30-50g/cm), temperature resistance (60), elongation ( >400)

Uses: Stable adhesion, good adhesion, good peeling performance, no residual glue, suitable for furniture boards, stainless steel plates, ceramic tiles, marble, artificial stone, etc.

4. Medium sticky protective film

Characteristics: Thickness (≥0.05±0.003), Width (≤1.3), Height (100-1000), Base Material (PE), Peel Strength (60-80g/cm), Temperature Resistance (60), Elongation (> 400)

Uses: Stable adhesion, good adhesion, good peeling performance, no residual glue, suitable for surface protection of fine-grained frosted boards and general hard-to-stick materials.

5. High viscosity protective film

Characteristics: Thickness (≥0.05±0.003), Width (≤1.3), Height (100-800), Base Material (PE), Peel Strength (80-100g/cm), Temperature Resistance (60), Elongation (> 400)

Uses: Stable adhesion, good adhesion, good peeling performance, no residual glue phenomenon, suitable for fine grain frosted board, aluminum plastic board, difficult to stick plastic plate, etc.

6. Ultra high viscosity protective film

Characteristics: Thickness (≥0.04±0.003), Width (≤1.3), Height (100-800), Base Material (PE), Peel Strength (above 100g/cm), Temperature Resistance (60), Elongation (>400 )

Uses: Very high viscosity, using water-based acrylic as pressure-sensitive adhesive, easy to use, easy to stick and tear, no residual glue phenomenon, suitable for hard-bonded materials such as rough aluminum plate.
