Solution

PE blown film production line is a common plastic processing equipment used to produce various plastic films, such as food packaging film, agricultural covering film, building insulation film, etc. During the production process, impurities and foreign matter may exist in raw materials such as PE, which will have an adverse effect on the quality of the film and even cause production line failure. Therefore, installing a melt filter is an important measure to solve product quality problems and improve the purity of the film in the PE blown film production line.

The main function of installing a melt filter in the PE blown film production line is to filter impurities and foreign matter in the melt to ensure that the quality of the produced film is stable and uniform. Specifically, installing a melt filter can solve the following problems:

1. Reduce defects such as black spots and bubbles on the surface of the film. Impurities and foreign matter in the melt will form defects such as black spots and bubbles on the surface of the film, affecting the appearance quality of the film. Installing a melt filter can effectively filter these impurities and reduce defects on the surface of the film.
2. Improve the physical properties of the film. Impurities and foreign matter in the melt will affect the physical properties of the film, such as tensile strength and heat resistance. Installing a melt filter can effectively filter these impurities and improve the physical properties of the film.
3. Extend the service life of the production line. Impurities and foreign matter in the melt will cause corrosion and wear to the production line equipment. Installing a melt filter can reduce these effects and extend the service life of the production line.

In summary, installing a melt filter is very necessary for PE blown film production lines. By filtering impurities and foreign matter in the melt, the quality of the produced film can be guaranteed to be stable and uniform, the physical properties of the film can be improved, and the service life of the production line can be extended, thereby improving production efficiency and economic benefits.
