<p><P>PROBLEM TO BE SOLVED: To provide a laminate constituted by laminating a nonwoven fabric and a thermoplastic resin layer, excellent in the stability of a seal part when adapted to the constitutent material of a disposable body warmer or the like, reduced in the change of the sensing temperature of the human body with respect to a change in the temperature of the open air, also excellent in recyclability and capable of simply corresponding to the sorting due to floating and sedimenting separation or the like at the time of recycling. <P>SOLUTION: This laminate 1 is composed of the nonwoven fabric 2 made of polypropylene and a polypropylene resin layer 3 and characterized in that the tensile elastic modulus in the MD direction of the polypropylene resin layer 3 is 200 MPa or above and the mutual seal strength of the propylene resin layers 3, when the propylene resin layers 3 are mutually heat-sealed, is 8 N/15 mm or above. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
