Abstract
A stretch laminate includes a first layer including a skinned or skinless elastomer film, the first layer having a surface, and a second layer including a nonwoven material, the second layer having a basis weight of less than about 25 gsm and a surface that is attached to the surface of the first layer. The elastomer film has a strength of an engineering tensile strength, at an engineering strain rate of about 600/s, of at least one of about greater than about 14 MPa for a plain specimen or about greater than about 7 MPa for a notched specimen. A method of making the stretch laminate and an absorbent article having at least one region defined by the stretch laminate are also provided.
Claims21
A stretch laminate comprising:
- a first layer comprising an elastomer film having a skin, the first layer having a surface;
- and
- a second layer comprising a nonwoven material, the second layer having a basis weight of less than about 25 gsm and a surface that is attached to the surface of the first layer,
- the elastomer film having an engineering tensile strength, at an engineering strain rate of about 600/s, of at least one of about greater than about 14 MPa for a plain specimen or about greater than about 7 MPa for a notched specimen.
A method of making a stretch laminate, the method comprising:
- providing an elastomer film having a skin,
- the elastomer film having an engineering tensile strength, at an engineering strain rate of about 600/s, of at least one of about greater than about 14 MPa for a plain specimen or about greater than about 7 MPa for a notched specimen;
- attaching a nonwoven layer having a basis weight of less than about 25 gsm to the elastomer film to form an assembly.
An absorbent article having a waist region and a crotch region, the article comprising:
- a backsheet having a longitudinal axis;
- a topsheet attached to the backsheet and having a body-facing surface;
- an absorbent core disposed between the backsheet and the topsheet;
- and
- a stretch laminate defining at least one region of the absorbent article, the stretch laminate comprising:
- a first layer comprising an elastomer film having a skin, the first layer having a surface;
- and
- a second layer comprising a nonwoven material, the second layer having a basis weight of less than about 25 gsm and a surface that is attached to the surface of the first layer,
- the elastomer film having a strength of an engineering tensile strength, at an engineering strain rate of about 600/s, of at least one of about greater than about 14 MPa for a plain specimen or about greater than about 7 MPa for a notched specimen.
