ABSTRACT:
Light-tight packaging (10) for photosensitive web roll (R) has a flexible material portion (24) detachably attached to a leading end portion (18) of the roll (R) that over wraps the outermost first convolution (20) of the roll (R). Opaque end members (22) are attached to the core (21) of the roll (R). First, second and third stretchable segments (28,30,32) of the flexible material portion (24) having widths wider than or equal to the length of the roll overlap the outermost first convolution (20) of the roll (R) to form successive outermost convolutions comprising the respective stretchable segment. Alternate stretchable segments overhang the end peripheral edges (16) of the roll (R) and overlap and compressively seal the end members (22) to the annular faces (12,14) of the roll (R). Folded overlapped portions (36,40) on the annular faces (12,14) form a labyrinth-type seal (42) on the annular faces (12,14) which cooperate with the compressively sealed opaque end members (28) to resist the ingress of light to the roll (R). In an alternative embodiment, a cushioning layer (112) is provided on anyone of the sequentially stretchable segments for absorbing shock and abrasions during web roll handling.
