ABSTRACT:
A 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 having radially arranged perforations are held in place by adhesive tape strips. 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, a tear is initiated in the end disks at one of the perforations, and the end disks tear circumferentially, whereby the folded-over portions adhere to the leader when the leader separates from the roll.
