    • An elastic laminate material (20) comprising at least one elastic film layer and at least one nonwoven layer, said elastic film layer and said nonwoven layer being bonded together in a bonding pattern comprising a plurality of bonding elements (10,11 ), in which said elastic film and said nonwoven are fused together, wherein the elastic film is in a stretched condition in a machine direction (MD) during bonding. The bonding pattern comprises at least two different types of bonding elements, wherein a first type of bonding elements (10) have a perimeter (p1 ), said perimeter having a length (a1) of at least 1.25 mm extending in a direction forming an angle of between 80 and 100° to said machine direction (MD), and a second type of bonding elements (11) having a perimeter (p2), said perimeter having a length (a2) of not more than 1 mm extending in said direction. Apertures (12) are formed in the elastic film in close vicinity of at least some of the first type of bonding elements (10), said apertures being caused by rupture of the elastic film as a result by stretching. The invention further refers to an absorbent article containing the elastic laminate.
    • 包括至少一个弹性膜层和至少一个非织造层的弹性层压材料(20),所述弹性膜层和所述非织造层以包括多个接合元件(10,11)的接合图案结合在一起,其中 所述弹性膜和所述无纺布熔合在一起,其中所述弹性膜在接合期间处于沿机器方向(MD)的拉伸状态。 接合图案包括至少两种不同类型的接合元件,其中第一类型的接合元件(10)具有周边(p1),所述周边具有沿形成角度的方向延伸的至少1.25mm的长度(a1) 与所述机器方向(MD)成为80°和100°之间,以及具有周长(p2)的第二类型的接合元件(11),所述周边的长度(a2)在所述方向上延伸不超过1mm。 孔隙(12)在弹性膜中形成在至少一些第一类型的接合元件(10)附近,所述孔是由于拉伸而使弹性膜断裂引起的。 本发明还涉及含有弹性层压材料的吸收制品。
