摘要:
1. A stretch laminate comprising: an elastomeric film layer comprising: from 53 to 65 percent by weight of SEEPS elastomeric block copolymer having a rubber middle block of a hydrogenated copolymer of isoprene and butadiene; from 8 to 15 percent by weight of a thermoplastic polymer additive; from 10 up to 20 percent by weight of a tackifier; iot from 10 to 20 percent by weight of plasticizer; a layer of non-woven fabric formed from fibers, while the fibers contain one or more polyolefins; adhesive located between the layer of elastomeric film and the layer of non-woven fabric. 2. The stretch laminate according to claim 1, characterized in that the adhesive includes a hot-melt adhesive. 3. The stretch laminate according to claim 1, characterized in that the adhesive contains: from 10 to 45 percent by weight of a block copolymer; from 40 to 80 percent by weight of a substance to increase stickiness; Ido 15 percent by weight of plasticizer. 4. The stretch laminate according to claim 1, characterized in that the adhesive contains: at least one homogeneous polyolefin copolymer of ethylene with propylene or alpha-olefins; up to 60 percent by weight of the substance to increase the stickiness; up to 15 percent by weight of plasticizer. 5. The stretch laminate according to claim 1, characterized in that the tackifier has a molecular weight Mn from 500 g / mol to 2000 g / mol. The stretch laminate according to claim 1, characterized in that the plasticizer is selected from the group consisting of synthetic and natural oils and their hydrogenated variants; naphthenic oils; paraffin oils; olefin oligomers and low molecular weight polymers; vegetable oils; animal oils; waxes of petroleum origin; and mixtures thereof. 7. Stretch laminate according to claim 1,1. Растягивающийся ламинат, содержащий:слой эластомерной пленки, содержащий:от 53 до 65 процентов по массе SEEPS эластомерного блок-сополимера, имеющего каучуковый средний блок из гидрогенизированного сополимера изопрена и б
