Elastic laminate

An elastic laminate comprising

• a multilayer film comprising at least two first elasticity skin layers and at least one second elasticity core layer, the first elasticity skin layers arranged on both sides of the at least one second elasticity core layer, said second elasticity core layer having higher elasticity than the sandwiching first elasticity skin layers, wherein the first elasticity skin layers comprise an olefin polymer, and the second elasticity core layer comprise an elastomer layer, and
• said multilayer film having arranged on both outer surfaces thereof non-woven layers bonded either (i) through hotmelt pressure-sensitive adhesive layers or (ii) ultrasonic bonding or thermal bonding,
• wherein the elastic laminate has an elongation strength of less than 20 N/50 mm width as elongated by 50% with 300 mm/min elongation speed,
• wherein the total film thickness of the multilayer film is in the range of 26 to 60 μm,
• the ratio of the total thickness of the first elasticity layers to the total thicknesses of the second elasticity core layer(s) is in the range of 1:10 to 1:25,
• wherein a laminated ratio of activation area is 8% to 49%,
• wherein an activation ratio is from 150% to 300%,
• wherein the non-woven fabric layers are selected from spunbonded non-woven or carded non-woven, and
• wherein predetermined parts of the elastic laminate have been subjected to an extension treatment, wherein the fiber structure of the non-woven fabric layers on said predetermined parts of the elastic laminate is mechanically loosened.
