Abstract

See full text

A laminate of an at least partially reticulated thermoplastic film joined to an extensible carrier. The reticulated thermoplastic film includes a backing with openings and discrete elements protruding from the first major surface. There are two discrete elements aligned in a first direction abutting opposite ends of any given opening. In a second direction perpendicular to the first direction, there is one discrete element between the given opening and an adjacent opening aligned in the second direction. Each portion of the thermoplastic backing around the given opening is plastically deformed in its lengthwise direction. A method of making a laminate is also disclosed. The method includes stretching a thermoplastic backing having a plurality of discrete elements in the first direction and laminating the backing to an extensible carrier. Subsequently stretching the laminate in a second direction forms a tear in the thermoplastic backing between two adjacent of the discrete elements.
