First claim
Opening claim text (preview).
What is claimed is: 1. An elastic laminate sheet comprising a laminate body having an elastomer film and a nonwoven material, wherein a 50% return load of the elastomer film after elongating 100% two times is 0.8 N/25 mm or higher; and the elastomer film and the nonwoven material are laminated together in the absence of pressure and are uniformly bonded with a bonding strength of 4 N/25 mm or less. 2. The elastic laminate sheet according to claim 1 , wherein nonwoven material is provided on both sides of the elastomer film. 3. The elastic laminate sheet according to claim 1 , wherein a basis weight of the elastomer film is 60 g/m 2 or less. 4. A laminate sheet comprising a laminate body having an elastomer film and a nonwoven material provided on at least one surface of the elastomer film, wherein the laminate sheet contains a low elasticity laminate portion and a high elasticity laminate portion; and in the high elasticity laminate portion, a 50% return load of the elastomer film after elongating 100% two times is 0.8 N/25 mm or higher, and the elastomer film and the nonwoven material are laminated together in the absence of pressure and are uniformly bonded with a bonding strength of 4 N/25 mm or less. 5. The laminate sheet according to claim 4 , wherein nonwoven material is provided on both sides of the elastomer film. 6. The laminate sheet according to claim 4 , wherein a basis weight of the elastomer film is 60 g/m 2 or less. 7. An article comprising the elastic laminate sheet according to claim 1 . 8. An article comprising the laminate sheet according to claim 4 .
