PE protection film is a kind of surface protective film which is more common in our daily life. Because of its good adhesiveness, docile and no residue, it is widely used in mobile phones, notebook computers, TV screen surfaces, lcd screens, etc. field.
In the production process of PE protection film, the processing temperature of the barrel is appropriately increased and the method of polycooling is adopted. The transparency of the film can be increased. In fact, in order to produce a transparent PP film, a water quenching method must be used. For example, if air cooling is used, the produced PP inflation film is vague and translucent due to poor cooling effect. For this reason, an appropriate increase in processing temperature and high-efficiency cooling means in production are effective ways to improve transparency. A small amount of a polyacrylate resin excellent in transparency and compatibility with a PE protection film or a PP protective film is added.
The raw material of PE protection film is LLDPE, which is soft in material and has certain stretchability. The thickness is generally 0.05MM-0.15MM, and the viscosity varies from 5G-500G depending on the application requirements. There are also electrostatic film and textured film under the protective film project of PE material. The electrostatic film is a kind of protective film with electrostatic adsorption force. It is a kind of protective film with no glue at all. Of course, the viscosity is relatively weak, and it is mainly used for surface protection such as electroplating.
The problem of PE protection film encountered by each user is different, and a targeted analysis is required before a solution can be made.www.snpefilm.com
