Responsive Film With Corrugated Microlayers Having Improved Properties

January 10, 2005

A drapable, wettable, multi-microlayer film comprising a plurality of coextruded microlayers was patented. The film includes at least a first corrugated microlayer of a polymer having a first recovery percentage and at least a second corrugated microlayer of a polymer having a second recovery percentage, wherein the first corrugated microlayer defines a first set of channels and the second corrugated microlayer defines a second set of channels aligned substantially perpendicular to the first set of channels. The second corrugated microlayer is partially delaminated from the first corrugated microlayer.
