[0002] Photocuring refers to the curing process of monomers, oligomers or polymer matrices under light induction, which is generally used in the film-forming process. Release film refers to a film with a differentiated surface. During the production process of photocurable release film, a film blowing machine is required to heat the plastic particle raw materials of the photocurable release film, melt it, and then blow it into a film.
