The phenomenon of high content of slip agent in PE protective film and the solution
Nov 23, 2022
Since the content of the slip agent in the heat-sealing layer of the PE film is too high, a large amount of it will precipitate out on the surface of the PE film to form a dense layer, which hinders the heat-sealing of the PE film. This can happen if an expired PE film is used.
Therefore, it is necessary to select the appropriate resin grade according to the specific requirements of customers, and try not to use expired films for high-slip products. After this phenomenon occurs, it is recommended to use a solvent to wipe the hot cover repeatedly, and the effect will be improved.
