Abstract
A 120-type roll photo film has a photo filmstrip. Trailer and leader portions of backing paper project from respective ends of the photo filmstrip. The photo filmstrip is wound about a spool with the trailer and leader portions. A seal tape is previously secured to the trailer portion. The photo filmstrip, after being exposed, is wound with the trailer and leader portions in a form of a roll with the leader portion internally positioned. Then the seal tape is fitted on the roll for preventing the trailer portion from being unwound. In the seal tape, a support material has first and second ends and an intermediate portion. The support material is folded into three in a Z-shape along first and second fold lines located between the intermediate portion and each of the first and second ends. A first adhesive layer attaches the first end to the trailer portion. An auxiliary adhesive layer attaches the intermediate portion to the first end in a peelable manner. A second adhesive layer is overlaid on the second end, and confronts the intermediate portion. A release layer is overlaid on the intermediate portion, receives the second adhesive layer, and facilitates peeling of the second adhesive layer from the intermediate portion. When the second end is separated from the intermediate portion, the support material is unfolded. The second adhesive layer attaches the second end to the trailer portion.
