<p>PROBLEM TO BE SOLVED: To continuously manufacture a laminate sheet package body by forming predetermined fold-tendency lines on a rectangular laminated sheet in positions at a plurality of ridges of a package body video cassette, and forming a note taking surface by a mat ink-treated surface on the outer surface of the laminated sheet. SOLUTION: When a laminate sheet is wrapped around a video cassette, the other end of the laminate sheet lies on a heat-sealing overlap width. The laminate sheet is entirely provided with a mat ink-treated layer 3 except the heat-sealing overlap width, thereby enabling note taking to be implemented. A strip 1 of the laminate sheet, when a video cassette is packaged, is provided with four fold-tendency lines in parallel in the longitudinal direction on lines at each ridge of the video cassette. The fold-tendency lines 2 can be made by providing wedge groove lines as shown in cross-section by putting a half-cut roller from the inner surface film side of the laminate sheet.</p> |
