ABSTRACT:
An improved light-tight package for a roll of a length of web material such as photographic paper or film. The package includes an opaque leader wound around the roll. Folded-over portions of opaque tearable flexible end disks are held in place by adhesive tape strips. A rigid disk is positioned intermediate the end disks and the end surfaces of the roll. In a preferred embodiment, the adhesive tape is tearable and the leader includes a portion adapted to initiate a tear in the tearable tape and the end disks. Upon unrolling of the package by pulling the leader, the tape tears, and the end disks tear circumferentially, whereby the folded-over portions adhere to the leader when the leader separates from the roll, and the rigid disks provide support for the flexible end disks.
