Methods and devices for processing polymer films

摘要

Stretched polymeric films can be used in a variety of applications, including optical applications. The stretching conditions and shape of the stretching tracks (64) in a stretching apparatus can determine or influence film properties. Take-away systems (140, 140', 141, 141') can be used to receive the film after stretching. The configuration of the take-away system can, in at least some instances, influence final film properties.
