摘要:
According to a process for producing a thermoplastic resin film according to one aspect of the present invention, a molten resin, while the molten resin is discharged from a die and thereafter lands onto a cooling roller, is uniformly heated in a direction of a flow by a heater. Thereby, a thermoplastic resin film having very slight thickness unevenness in a longitudinal direction can be formed. Moreover, according to the process for producing a thermoplastic resin film, heating by the heater can reduce a viscosity of the molten resin at the time of landing, and can suppress generation of retardation at the time of landing.
摘要(中):
根据本发明的一个方面的热塑性树脂膜的制造方法,将熔融树脂从模具排出,然后落在冷却辊上,在流动方向上均匀地加热熔融树脂 一个加热器。 由此,能够形成长度方向的厚度不均匀的热塑性树脂膜。 此外,根据热塑性树脂膜的制造方法,通过加热器的加热可以降低着陆时的熔融树脂的粘度,能够抑制着落时的延迟的产生。
