Abstract
Methods and systems for making a film made of dynamically vulcanized thermoplastic elastomeric material are provided herein. The subject methods and systems achieve dimensional stability of an elastic film by applying thermal treatment as part of the film making process and enhance the shrinkage of the film by intentionally with stretching the film while hot and freezing the film in the stretch. The systems and methods are useful in controlling shrinkage of DVA post film extrusion.
