Explain the stickiness and color of PE protective film

Page view
PE protective film is one of the most common materials in protective film, and it is also the most widely used polymer material in the world today. Mainly used in hardware industry, optoelectronics industry, plastics industry, printing industry, wire and cable industry, electronics industry, mobile phone digital industry. The PE protective film is distinguished by its thickness, color, adhesiveness, use, etc. The user can select suitable materials according to the product used. With regard to the stickiness of PE protective film, many company definitions are different. After years of experience in the industry, the author summarized the following divisions of the protective film's viscosity:
According to the main adhesion force is: ultra-low-viscosity protective film, low-viscosity protective film, low-viscosity protective film, medium-viscosity protective film, high-viscosity protective film, ultra-high-viscosity protective film;
1. Ultra-low-viscosity protective film (ie, micro-bottom adhesive)
Peel strength (≤ 5g/cm), stretch rate (>400), easy to use, easy to tear, no residue phenomenon. Suitable for organic plates, instruments, displays, glass lenses, plastic lenses, etc.
2. Low-viscosity protective film
Peel strength (10-20g/cm), elongation (>400), stable adhesion, good adhesion, good peeling performance, no adhesive residue. Applicable to steel mirror plate, titanium metal, smooth plastic plate, screen printing, Mingming brand and so on.
3. Low-viscosity protective film
Peel strength (30-50g/cm), elongation (>400), stable adhesion, good adhesion, good peeling performance, no adhesive residue. For furniture Polaroid plate, stainless steel plate, tile, marble, artificial stone and so on.
4 in the protective film
Peel strength (60-80g/cm), elongation (>400), stable adhesion, good adhesion, good peeling performance, no adhesive residue. Suitable for fine-grained frosted panels and general surface protection of difficult-to-stick materials.
5. High-viscosity protective film
Peel strength (80-100g/cm), stretch rate (>400), stable adhesion, good adhesion, good peeling performance, no adhesive residue. Suitable for fine-grained frosted panels, aluminum-plastic panels, difficult to stick Plastic plates and so on.
6. Ultra high viscosity protective film
Peel strength (above 100g/cm), stretch rate (>400), high stickiness, use water-based acrylic as pressure-sensitive adhesive, easy to use, easy to paste, easy to tear, no residue phenomenon. Suitable for rough-aluminum and other difficult to stick material.
In actual operation, the PE protective film must be tested first, because the viscosity of the protective film will change due to external factors such as air temperature and humidity. Therefore, it is recommended that each customer must test the sample.
PE protective film color
There are many color classifications of PE protective film. Let's talk about the color classification today. The reason why there are a variety of colors, mainly based on the use of different.
The color can be roughly divided into several types.
1. Transparent pe protective film: it is colorless.
2. Milky pe protective film: a more common color.
3. Blue pe protective film: more used in glass protection. Divided into translucent and opaque.
4. Red pe protective film: relatively rare.
5. Yellow pe protective film: Yellow tape is a common one.
6. Printing pe protective film: This is strictly speaking not a color classification, but it is necessary to list here.
