    • There is provided a nonwoven elastic laminate closure tab of the invention comprising adjacent first and second nonwoven closure elements each having a first face and a second face and a coextruded film elastic attached to each closure element first face. The first face of each closure element has a first area coated with a pressure sensitive adhesive and a second area adjacent the first area free of pressure-sensitive adhesive at terminal ends of the nonwoven closure elements. The coextruded film elastic has two first regions each having at least one inelastic zone and a second region between the two first regions having at least one elastic zone. The two opposing first regions are attached to the two pressure-sensitive adhesive areas of the two closure elements respectively such that the second adhesive free areas of the two adjacent closure elements are in face to face contact with at least a portion of the coextruded elastic film elastic second region. The layers are all of a thickness such that the thickness variation across the closure tab is less than 50%.
    • 提供了本发明的非织造弹性层压封闭接头,其包括相邻的第一和第二非织造材料封闭元件,每个具有第一面和第二面以及附着到每个封闭元件第一面的共挤出膜弹性。 每个封闭元件的第一面具有涂覆有压敏粘合剂的第一区域和邻近第一区域的第二区域,在无纺布封闭元件的末端处没有压敏粘合剂。 共挤出薄膜弹性体具有两个具有至少一个非弹性区域的第一区域和具有至少一个弹性区域的两个第一区域之间的第二区域。 两个相对的第一区域分别附接到两个封闭元件的两个压敏粘合剂区域,使得两个相邻的封闭元件的第二粘合剂自由区域与共挤出的弹性膜的至少一部分面对面接触 弹性第二区域。 这些层都具有这样的厚度,使得在闭合突片上的厚度变化小于50%。
