<p><P>PROBLEM TO BE SOLVED: To provide a composite material having high extensibility and half-elasticity, especially a composite material for fastening elements of a diaper. <P>SOLUTION: This invention relates to a composite material having high extensibility and half-elasticity, and especially to a composite material for the fastening elements of the diaper. The composite material has an outer layer made of non-woven fabric, and a polyethylene film made of the polyethylene type of a PE-LD and a PE-LLD inserted and laminated as a stripe or plane material extended to the edge of the outer layer. The film thickness of the polyethylene film is 5 to 20μm. The composite material further has an activation region in which the composite material is half-elastically expansible by stretching, and a non-activation region in which the composite material is rigid. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
