Single sided stretch bonded laminates, and methods of making same

An elastic single sided stretch bonded laminate comprising:

• an elastic layer comprising an array of continuous filament strands with a meltblown layer deposited on said continuous filament strands, wherein the continuous filament strands comprise an elastic polyolefin-based polymer having a degree of crystallinity between about 3% and about 40%, the continuous filament strands comprise at least one of the group consisting of ethylene methacrylate, polyisobutylene, and butyl acrylate;
• an adhesive that demonstrates a relatively short open time deposited between the array of continuous filament strands and the meltblown layer, wherein the open time of the adhesive is between about 0.2 seconds and 1 minute;
• and
• a facing layer bonded to only one side of said elastic layer;
• wherein the laminate has an inter-layer peel strength of less than about 70 grams per 3 inches cross-directional width at a strain rate of 300 mm/min and eliminates roll blocking.

An elastic single sided stretch bonded laminate comprising:

• an elastic layer comprising an array of continuous filament strands with a meltblown layer deposited on said continuous filament strands, wherein the meltblown layer comprises at least two layers, with a first layer comprising an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40% and a second layer comprising a styrenic block copolymer-based meltblown polymer, the elastic polyolefin meltblown polymer comprises at least one of the group consisting of ethylene methacrylate, polyisobutylene and butyl acrylate;
• and
• a facing layer bonded to only one side of said elastic layer, wherein the facing layer comprises an elastic polyolefin-based polymer having a degree of crystallinity between about 3% and about 40%;
• wherein the laminate has an inter-layer peel strength of less than about 70 grams per 3 inches cross-directional width at a strain rate of 300 mm/min and eliminates roll blocking.
