<p><P>PROBLEM TO BE SOLVED: To provide a composite sheet excellent in breathability while ensuring dampproofness, excellent in impact resistance by dispersing and absorbing a bag drop impact, and reduced in material and finished volume, and a composite bag using the same. <P>SOLUTION: In bonding a meshed plastic sheet 3 to a paper sheet 2, a non breathable laminating resin 4 for bonding is supplied to the meshed plastic sheet 3 with both of the sheets 2, 3 brought into close contact with each other to cover the entire surface of the meshed plastic sheet 3, the paper sheet 2 and the meshed plastic sheet 3 are bonded together to form an unbonded part 7 by close contact parts of both of the sheets and to form a strongly bonded part 5 by not close contact parts of both of the sheets, thereby obtaining the composite sheet excellent in dampproofness and breathability, excellent in impact resistance because the unbonded part 7 functions as a deaeration passage 6 to disperse and absorb the impact, and reduced in material and finished volume, and the composite bag using the same. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
