PROBLEM TO BE SOLVED: To provide a multilayered tape excellent in pressure resistance and easy opening properties, simple in its manufacturing process and capable of being reduced in cost, its manufacturing method and a packaging object. SOLUTION: In the cross section of the multilayered tape 2A, a first surface layer 21 becomes non-uniform in thickness in the width direction of the multilayered tape 2A. Thinely formed thin-walled parts 211 and 212 are provided to both ends of the first surface layer 21 and thickly formed thick-walled part 213 is provided so as to be held between the thin-walled parts 211 and 212. A protruded part is formed by the thin-walled parts 211 and 212 and the thick-walled part 213. Herein, the thin-walled parts 211 and 212 become a region easy to break or peel and the thick-walled part 213 becomes a region hard to break or peel. Further, the intermediate layer 23 adjacent to the first surface layer 21 is formed into a recessed part so as to be occluded with the protruded part. COPYRIGHT: (C)2008,JPO&INPIT
