Abstract
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 (105) 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 (106) 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 (105) in said film have a tear-strength as measured by an Elmendorf Tear Test of at least 30g; and
wherein said second zones (106) in said film have a tear-strength as measured by an Elmendorf Tear Test of at least 50g.
