Abstract: A package for a roll of light-sensitive strip material is disclosed and includes end covers and a leader which are opaque and moistureproof. A rim or peripheral lip on each end cover overlies an edge of the leader and is adhered thereto, but no adhesive is used between the end covers and the ends of the roll so that the edges of the strip material do not pick up adhesive. The assembled roll and its package may be roomlight loaded into exposure apparatus such as a camera, magazine, cassette, etc. with a portion of the leader extending from the roll. After the exposure apparatus has been sealed to light, the remainder of the leader may be stripped from the roll, tearing the end cover rims away from the rest of the end covers so that successive convolutions of strip material may be unwound from the roll.
