CA 2165763

An improved light-tight package for a roll (10) of a length (14) light- sensitive material such as photographic film or paper includes an opaque leader (22) wound around the roll. Folded-over portions (48, 50) of opaque end disks (32, 34) are held in place by adhesive tape strips (44, 46). Upon unrolling one embodiment of the package by pulling the leader, the end disks release from the adhesive strips without tearing; and the adhesive strips remain attached to the leader and are removed from the roll with the leader. Upon unrolling another embodiment, the end disks tear circumferentially and the torn-away portions are removed with the tape strips and the leader.
