A METHOD FOR PRODUCING PLASTIC FILM

摘要

In one embodiment, the film making process can comprise: introducing a plastic melt to a nip between a calendar roll and a resilient roll, passing the plastic melt between the calendar roll and the resilient roll to produce the film, and controlling a roughness of the film by actively cooling an external surface of the resilient roll. In another embodiment, the film making process can comprise: introducing a plastic melt having a melt temperature to a nip between a calendar roll and a resilient roll, passing the plastic melt between the calendar roll and the resilient roll to produce the film, and adjusting a roughness of the film at a constant production rate and a constant nip pressure.
