A sheet film package contains a sheet film unit in a light-shielding envelope with an open end through which the sheet film unit is movable into and out of the light-shielding envelope. The light-shielding envelope is formed by folding a sheet of light-tight material in half to provide a folded side, and securely sealing joints of the folded sheet along a side opposite side to the folded side as well as an end opposite to the open end, wherein a middle portion of the folded side has a larger folding angle compared with end portions thereof.
