摘要：
In one embodiment, the present invention relates to an extrusion bonded laminate (202) including an elastomeric film (206) directly bonded to at least one nonwoven web layer (214, 218) substantially continuously over at least a major portion of the laminate (202), in which the laminate (202) is extensible in at least one direction, and in which the elastomeric film (206) includes a vinyl arene-containing block copolymer, and in which the elastomeric film (206) is substantially free of a tackifying amount of a tackifier, and to a process for producing an extrusion bonded laminate (202). In one embodiment, the total vinyl arene content of the elastomeric film (206) is about 30 % or less. The extrusion bonded laminate (202) is useful, for example, in a diaper tab.
摘要（中）：
在一个实施方案中，本发明涉及挤出粘合的层压体（202），其包括直接结合至至少一个非织造纤维网层（214,218）的弹性体膜（206），其基本上连续地层压在层压体（202）的至少大部分上 ），其中所述层压体（202）在至少一个方向上是可延伸的，并且所述弹性体膜（206）包括含乙烯基芳烃的嵌段共聚物，并且其中所述弹性体膜（206）基本上不含增粘 增粘剂的量，以及挤出粘合层压体（202）的制造方法。 在一个实施方案中，弹性体膜（206）的总乙烯基芳烃含量为约30％或更少。 挤出粘结层压体（202）可用于例如尿布片。
