An elastic laminate capable of being rolled for storage and unwound from a roll when needed for use, includes an elastic layer of an array of continuous filament strands with meltblown deposited on the continuous filament strands, and a facing layer bonded to only one side of the elastic layer. The meltblown layer may include an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%. The laminate suitably 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. Alternatively or additionally, the continuous filament strands and/or the facing layer may include an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%. In certain embodiments, the elastic laminate may include an extensible facing layer bonded to an elastic or semi-elastic film layer having a basis weight of about 50 gsm or less, wherein the facing layer includes an elastic polyolefin-based polymer having a degree of crystallinity between about 3% and about 40%.
What is claimed is: 1. An elastic single sided stretch bonded laminate comprising:an elastic layer comprising an array of continuous filament strands with an elastic meltblown layer deposited on said continuous filament strands, wherein the elastic meltblown layer comprises an elastic polyolefin-bas
What is claimed is: 1. An elastic single sided stretch bonded laminate comprising:an elastic layer comprising an array of continuous filament strands with an elastic meltblown layer deposited on said continuous filament strands, wherein the elastic meltblown layer comprises an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%, the polyolefin-based meltblown polymer comprises at least one of the group consisting of ethylene methacrylate, polyisobutylene and butyl acrylate; anda 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.
