본 발명은 하나이상의 탄성중합체층 (3) 및 하나이상의 얇은 외피층 (2,4)을 포함하고, 상기층들을 공압출시킨 후 외피층의 탄성 한계치를 초과하는 수준까지 라미네이트를 신장시킨 후 원상복귀시킴으로써 제조하는 것이 바람직한 마이크로 텍스쳐의 탄성중합체 라미네이트(1)에 관한 것이다. Microtextured elastomeric laminates comprising at least one elastomeric layer and at least one thin skin layer is preferably prepared by coextrusion of the layers followed by stretching the laminate past the elastic limit of the skin layers and then allowing the laminate to recover.
