Abstract
The presently described technology provides a low cost multilayer elastomeric film containing at least one layer of styrene block copolymer and at least one elastomer layer substantially free of styrene block copolymer such that the resultant film has a low permanent set substantially equal to or less than a film comprised of styrene block copolymer only. The elastomeric film may be used in elasticized features of various articles, such as disposable absorbent articles. Methods for producing the low cost elastomeric film having a low permanent set are also described.
