BREATHABLE ELASTIC MULTILAYER FILM AND METHOD OF MAKING A BREATHABLE ELASTIC MULTILAYER FILM

摘要

A breathable, elastic, film laminate including layers of an inherently breathable, elastic polymer film alternately stacked with layers of a filled plastic polymer. The laminate may be made by grafting a thermoplastic polymer to an elastomer to form an inherently breathable elastic polymer, extruding, the elastic polymer through a die, extruding the filled plastic polymer through a die, stacking the extruded elastic polymer with the extruded plastic polymer while the polymers are in a melt-extrudable state to create a multilayer film laminate, and stretching the laminate.
