What are the Common Types of Protective Film Materials?

As a PE Self-Adhesive Protective Film Manufacturer, share it with you.

PET protective film is currently the most common type of protective sticker on the market, and its chemical name is polyester film. The characteristics of PET protective film are: the texture is relatively hard, relatively scratch resistant, and it will not turn yellow and oil like PVC material after long-term use. However, the general PET protective film relies on electrostatic adsorption, which is easier to foam and fall off, but even if it falls off, it can be reused after washing it in clean water. The price of PET protective film is much more expensive than that of PVC. When many well-known foreign brands of mobile phones leave the factory, they are equipped with PET protective stickers. The PET protective stickers are more exquisite in workmanship and packaging and can be used directly without cutting.

PE Self-Adhesive Protective Film

The main raw material of PE protective film is LLDPE, which is relatively soft and has certain stretchability. The general thickness is 0.05MM-0.15MM, and its viscosity varies from 5G-500G depending on the requirements of use (the viscosity is different between domestic and foreign countries, for example, 200 grams of Korean film is equivalent to about 80 grams in China). The protective film of PE material is divided into electrostatic film and anilox film. The electrostatic film, as its name implies, uses electrostatic adsorption as its adhesive force. It is a protective film with no glue at all. Of course, it is relatively weak and is mainly used for surface protection such as electroplating. Anilox film is a kind of protective film with many meshes on the surface. This kind of protective film has better air permeability and has a more beautiful paste effect, unlike plain weave film that will leave bubbles.

The protective film made of OCA is no different from other materials in appearance, but the protective film made of OCA is produced in Japan. It is now used most on Apple mobile phones. Its brightness and hardness are better than other materials. Therefore, OCA is the most popular material for mobile phone protective film.
