摘要

Disclosed is an elastomeric film comprising a layer comprising:(i) at least one olefin-based elastomeric polymer, said at least one olefin-based elastomeric polymer being selected from the group consisting of olefin block copolymer, olefin random copolymer, ethylene copolymer, propylene copolymer, and mixtures thereof, and (ii) at least one draw down polymer present in a combined amount from wt% to 25 wt% of said layer to produce the elastomeric film with a basis weight of no more than 25 gsm, said at least one draw down polymer being selected from the group consisting of linear low density polyethylene, high density polyethylene, homopolymer polypropylene, and mixtures thereof, wherein said elastomeric film has a basis weight of no more than 25 gsm and said elastomeric film has a permanent set, as measured per ASTM D882-97, of no more than 14% after recovery from being initially stretched to 100% of its original size.
