​Differences Between PE Protective Film, PVC Protective Film, and PET Protective Film

PE protective film is becoming more and more useful in its use, and its variety is everywhere in the market. the biggest advantage of PE protective film is that the products being protected are produced and processed in PE protective film and transported. In the process of storage and use, it will not be contaminated, corroded, and scratched, maintaining the original bright and shiny surface, which in turn improves the quality of the product and market competitiveness.

 Protective Film

Suitable for sticky PE protective film

1. PE protective film is easy to stick and easy to tear.

2. Long storage period: more than one year in storage, no change in quality.

3. peel force stability: little change over time, i.e. the smaller the increase in peel force, the better.

4. Good weather resistance: under the condition of sunlight, the use period is up to six months to one year.

5. No pollution, no corrosion: the adhesive is inert, no chemical reaction with the surface of the object to adhere.

6、Excellent mechanical properties: to meet the user's requirements for tensile strength, modulus of elasticity, elongation, etc. +

Protective Film For Marbles And Ceramics

PE protective film production principle

1. PE protective film adhesive (glue) has viscoelastic polymer, film, and tear film.

2. The main factors affecting the viscosity: are wetting, and penetration.

Film: the adhesive layer can be in close contact with the surface of the object to adhere and flow into the grooves of the surface of the object to be adhered as much as possible, thus increasing the effective contact area.

The main factors influencing the adhesion

Wetting: pressure-sensitive adhesive can only achieve close contact if the surface of the bonded material is well wetted, creating conditions for molecular movement and diffusion of physical and chemical bonds: pressure-sensitive adhesive molecules will move to the surface of the bonded material to be bonded material when the distance between the two combined is less than 5A, physical and chemical bonding will occur.

Protective Film for Aluminium Profiles and Plates

Differences between PE protective film, PVC protective film, and PET protective film

PE protective film

Polyethylene, widely used in the protective film industry

Its main features are: low price, soft, good extensibility, no environmental pollution, generally such products have passed the EU ROHS environmental pollution test.

Disadvantages: poor weather resistance, this material is not suitable for use in high temperatures, generally within 60 degrees.

 PET Protective Film

PVC protective film

Its characteristics are good flexibility, and good weather resistance (SPVC).

Disadvantages: not environmentally friendly, so many international brands rarely use this material. This product is mainly used mostly for anti-static protection, there is wooden speaker surfaces.

PET protective film

Its main features: good weather resistance, can withstand 100-150 degrees high temperature, good hardness, smooth.

Disadvantages: can not be used for products with angles or corners. Mainly used for die-cutting.
