In the past, there were problems in the packaging and transportation of some products. In the past, many of our products often had problems during transportation. The most common problem was wear and tear, which caused great economic losses. Because some items are basically useless once they are worn out. PE protective film is one of the most common materials in protective films, and it is also the most widely used polymer material in the world today. Mainly used in hardware industry, optoelectronic industry, plastic industry, printing industry, wire and cable industry, electronics industry, mobile phone digital industry.
Regarding the viscosity of PE protective film, according to the viscosity, it is mainly divided into: ultra-low viscosity protective film, low-viscosity protective film, medium-low viscosity protective film, medium-viscosity protective film, high-viscosity protective film, and ultra-high-viscosity protective film.
1. Ultra-low viscosity protective film (ie, micro bottom sticky):
Peel strength (≤5g/cm), elongation rate (>400), easy to use, easy to stick and easy to tear, no glue residue. Suitable for organic sheet, instrumentation, display screen, glass lens, plastic lens, etc. It is often called electrostatic film on the market.
2. Low viscosity protective film
Peel strength (10-20g/cm), elongation (>400), stable adhesive force, good adhesion, good re-peeling performance, no glue residue. Suitable for steel mirror plate, titanium metal, glossy plastic plate, silk screen, nameplate, etc. It is also often called electrostatic film on the market.
3. Medium and low viscosity protective film
Peel strength (30-50g/cm), elongation rate (>400), stable adhesive force, good adhesion, good re-peeling performance, no glue residue. Suitable for furniture Polaroid, stainless steel, ceramic tile, marble, artificial stone, etc.
4. Middle mucosa protective film
Peel strength (60-80g/cm), elongation (>400), stable adhesive force, good adhesion, good re-peeling performance, no glue residue. It is suitable for surface protection of fine-grained matte boards and general hard-to-stick materials.
5. High viscosity protective film
Peel strength (80-100g/cm), elongation (>400), stable adhesion, good adhesion, good peeling performance, no glue residue. Suitable for fine-grained matte board, aluminum-plastic board, difficult to stick plastic sheet, etc.
6. Ultra-high viscosity protective film
Peel strength (above 100g/cm), elongation rate (>400), high viscosity, water-based acrylic acid is used as pressure-sensitive adhesive, easy to use, easy to stick and tear, easy to appear residual glue phenomenon. Suitable for rough-grained aluminum plates, etc. Difficult to stick material.
