<p>PROBLEM TO BE SOLVED: To provide a cushion bag which improves a recycling rate of a paper sheet and a polymer as a cushioning material. SOLUTION: In a cushion bag, a cushion sheet is made of an olefin resin and its inner sheet has a functional-group-containing polyolefin layer on at least its one surface, the functional-group-containing polyolefin layer containingα,β-unsaturated carboxylic acids beyond 1000 ppm. A laminate sheet of the cushioning bag is obtained by superimposing the paper sheet and the functional- group-containing polyolefin layer of the inner sheet. By heat-sealing a peripheral portion except an open end, the facing inner sheets are fusion-bonded, so that the paper sheet and the inner sheet are stuck together.</p> |
