ABSTRACT:
Thermoplastic elastomeric films comprise from about 40% to about 80% of an elastomeric block copolymer and from about 20% to about 60% of an ethylene-vinyl acetate copolymer. The block copolymer has at least two monoalkenyl arene polymer end blocks and at least one elastomeric conjugated diene midblock. The monoalkenyl arene polymer blocks comprise from about 8% to about 55% by weight of the block copolymer. The block copolymer has a melt index of less than about 10. The ethylene-vinyl acetate copolymer comprises from about 22% to about 33% vinyl acetate and has a melt index of less than about 0.6. The film is from about 0.03 mm to about 0.15 mm in thickness.
