PROBLEM TO BE SOLVED: To provide a printing film for a cylindrical label, which hardly has a print color made thinner in the vicinity of an overlap part than in the other part, when being sealed by heat with one end on the other end. SOLUTION: A print film 1 has one end part 3 put on the other end part 2 and is formed like a cylinder by heat sealing, in such a state that an edge of a pressing surface of a seal bar is positionally deviated from a film end surface 3a of one end part 3 outward in the circumferential direction. A band-shaped print density adjustment area 9 printed with a higher density than an area around the area 9 is provided adjacent to an overlap area 7, in the other end part 2 of the print film 1.
