PURPOSE: To provide laminated tube containers that have no step due to lapping along a seam, and that have no defects in appearance such as a colored streak. CONSTITUTION: A laminated sheet comprising an intermediate layer 3 made of metal foil etc., heat-sealable synthetic resin layers 4, 5 on both sides of the intermediate layer 3, and a colored film layer 6 on the heat-sealable synthetic layer 4 is rolled to form a tube shell. The both ends 1, 2 of the sheet are cut aslant against its surface to form slant surfaces (a, b) for seaming. The slant surfaces (a, b) are heat-sealed integrally. |
