SOLUTION: A shopping bag or the like after use is classified into low density polyethylene and high density polyethylene, and, with the low density polyethylene as an intermediate layer, the high density polyethylene is laminated on both the sides in the surface layer, so as to be a sandwich shape, and heating and fusion are performed, so as to obtain a laminated sheet. The obtained laminated sheet can be utilized as members for a notebook cover, a bag, a porch or the like, and, as stock single articles, for a bookmark, a card case or the like.
