개선된 마이크로 질감의 외관을 갖는 보다 강한 탄성 적층체 및 그 적층체를 제조하는 방법이 본원에 개시된다. 특히, 본 발명은, 함께 공압출되고 연신된 후 이완된 적어도 하나의 열가소성 탄성중합체 필름 층 및 적어도 하나의 플라스틱 층을 포함하는 다층 탄성 적층체에 관한 것이다. 제조된 적층체는 전반적으로 향상된 강도 및 탄성을 가진다. Stronger elastic laminates having an improved microtextured appearance, as well as methods of preparing the laminates, are disclosed herein. Particularly, the present disclosure is directed to multilayered elastic laminates including at least one thermoplastic elastomeric film layer and at least one plastic layer coextruded together, stretched and then relaxed. The prepared laminates have enhanced overall strength and elasticity.
