Abstract
A sheet film package comprises a casing, a stack of sheet films stored in said casing, and a protective board disposed in said for protecting said sheet films. The protective board has a holder portion integrally joined to one side edge of an upper panel and/or a lower panel thereof for preventing the sheet films from being displaced in a direction transverse to the direction in which the sheet films wil be fed out. The sheet film package also includes a buffer sheet member disposed on the lower panel of the protective board for placing the sheet films on the buffer sheet member. The buffer sheet member has at least one opening such as a hole or a slit for leaking suction air in each of two symmetrical areas of the buffer sheet member, one of which will be contacted by a suction cup of a film delivery mechanism disposed in a device in which the sheet film package can be loaded. The buffer sheet member has a foamed sheet layer made of thermoplastic resin.
