Adsorption function and application fields of PE protective film
Sep 28, 2022
PE protective film is the simplest polymer organic compound and the most widely used polymer material in the world today. Today, I will tell you about the adsorption function and application fields of PE protective film. Let's take a look together.
The adsorption function and application fields of PE protective film:
In the production process of PE protective film, corona treatment is generally carried out, which will increase the surface area of the film and bring static electricity, and then carry out the subsequent gluing work, so that the film and glue can be well combined. .
The PE protective film will be effectively on the inner layer of the film. When it is produced, its main material is EVA, which has a certain adsorption function when it is used, so as to realize the entire adsorption function of the film. The electrostatic formula components of these two kinds of electrostatic films are also different, and the quality and price of the products are also different. The electrostatic film with low price and low grade will transfer the electrostatic components on the surface of the product, resulting in defective and scrapped products.
PE protective film is a common surface protective film in our daily life. Due to its high-quality features such as good adhesion, conformity and no glue residue, it is widely used in mobile phones, notebook computers, TV screen surfaces, lcd screens, etc. field.
In the production process of PE protective film, the processing temperature of the barrel is appropriately increased and the method of polycooling is adopted. The transparency of the film can be improved. In fact, to produce a transparent PP film, a water quenching method must be used. If air cooling is used, the PP blown film produced is fuzzy and translucent due to the poor cooling effect. For this reason, it is an effective way to improve the transparency by appropriately increasing the processing temperature and using high-efficiency cooling methods in production. A small amount of polyacrylate resin with good compatibility and excellent transparency is added to the PE protective film and PP protective film.
