Uses and Properties of PET Protective Film

PET protective film is also known as biaxially oriented polyester film (polyethylene terephthalate), with a density of 1.4g/cm³. PET protective film is a plastic film made of PET as the base material, coated with acrylic (or silicone, etc.) adhesive on one side and laminated with release film.

What is the purpose of PET film?

PET protective film is also known as high-temperature resistant polyester film. With excellent physical properties, chemical properties and dimensional stability, transparency, and recyclability, it can be widely used in magnetic recording, light-sensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, optical grade mirror protection, etc.

With the development of special functional films, new uses for polyester films are emerging. It can be produced into mobile phone LCD protection film, LCD TV protection film, mobile phone keys, etc.

It is used to maintain LCD, touch screens, mobile phones, digital cameras, and PDA screens to prevent scratching during use and to achieve the purpose of maintaining the screen.

The performance of PET protective film

PET protective film material is bright and colorless, with a hardened surface that resists scratching and abrasion. The silicone is coated with an optical grade glossy polyester film (PET), which is attached to a glossy polyester (PET) release film.

The PET protective film is removed without adhesive residue; it is non-reflective and adds a display of color. The general PET protective film material has a hardening value between 3H-4H depending on the origin, with better hardening and wear resistance.

Light transmission is also the primary performance of PET protective film materials. Generally, the light transmission rate is above 90%. The high light transmission not only gives us a good visual effect when using the relevant instruments but also has a good effect on both eyes.

Advantages of PET protective film

PET protective film is a packaging film with excellent overall performance. 

• PET protective film has good transparency and gloss; 

• PET protective film has good air tightness and fragrance retention; 
  

• PET protective film has moderate moisture resistance and reduced moisture permeability at low temperatures; 
  

• PET protective film has good strength and dimensional stability, suitable for printing, paper bags, and other secondary processing; 
  

• PET film also has excellent heat and cold resistance, as well as good chemical and oil resistance. 
  

• PET protective film has excellent mechanical properties, its strength is the best of all thermoplastics, and its tensile strength and impact strength are much higher than ordinary film.
  

The glue system of PET protective film production line from NB is acrylic glue and silicone, acrylic glue is the main, the glue performance is stable, good temperature and weather resistance. The viscosity of our regular products is usually below 60g, but we can also customize them according to the viscosity of customers. We can also produce PET grids and plain PET protective film upon request.
