A method for packaging a photosensitive film roll, which includes packaging the photosensitive film roll with a resin case. The photosensitive film roll is formed in a step by winding around a core, a photosensitive film comprising a supporting film and a photosensitive resin composition layer formed on the supporting film. The resin case is collapsible without generating any waste materials after the case is collapsed. The photosensitive resin layer includes a photosensitive resin composition containing a binder polymer and a photopolymerizable compound having at least one polymerizable ethylenically unsaturated group within a molecule and a photopolymerization initiator, and the resin case consists of a resin having a lower surface energy than the photosensitive resin composition.
