| Abstract: | This paper proposed a method to calculate the draw ratio of die head in the process of casting BOPET films.This paper also studied the relationship between the draw ratio of die head,die opening and casting thickness.The process steps for die openings,affecting factors of casting-film necking,requirement and control for edge film thickness gradients were investigated.The temperature distribution of curing reaction of melt PET films on cooling rollers,static techniques and control of film-casting film were further discussed. |
