摘要

A tear-resistant low set elastic film, comprising: a first layer and; a second layer comprising a blend of polyethylene with metallocene catalysed polyethylene or metallocene catalysed polypropylene; an elastic core layer bonded between said first layer and second layer; first zones in said film that have been activated and have sufficient elasticity to stretch at least 200% while maintaining a permanent set percent of no more than about 5%; second zones in said film that have not been activated and can stretch at least 200% while maintaining a permanent set percent of up to 5%; wherein said first zones in said film have a tear-strength as measured by an Elmendorf Tear Test of at least 30g; and wherein said second zones in said film have a tear-strength as measured by an Elmendorf Tear Test of at least 50g.
