Abstract

Provided is a stretchable laminate which fits excellently. Also provided is an article which contains this stretchable laminate. A stretchable laminate according to the present invention comprises a nonwoven fabric layer on at least one side of an elastomer layer, and has a permanent set of 10% or less after four hysteresis tests. An article according to the present invention contains this stretchable laminate.

Description

technical field [0001] The present invention relates to a stretchable laminate and a product including the same. Background technique [0002] Various stretchable laminates have been proposed for products such as sanitary products such as diapers and masks (for example, refer to Patent Documents 1, 2, and the like). For such an elastic laminate, it is important to have excellent fit properties that are comfortable for each of various users. [0003] However, the conventional elastic laminate has a problem of insufficient fit. [0004] [citation list] [0005] [Patent Document] [0006] [Patent Document 1] JP2012-187857A [0007] [Patent Document 2] JP3830818B2 Contents of the invention [0008] The problem to be solved by the invention [0009] The present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide a stretchable laminate having excellent fittability. In addition, another object of the present...
