Abstract (en)
[origin: EP0786695A1] Daylight packaging for photographic paper supplied in the form of large rolls having a width which corresponds with the format of the photographs to be printed, comprises a core sleeve onto which the photographic paper is wound; two circular side flanges heat sealed to the core sleeve to form a reel; and a leader attached at one end to the outer end of the paper and free at the other end, the leader being heat sealed to the side flanges at the outer periphery to seal the package. The side flanges have a multi-layer structure comprising a paper support e.g. about 130 mu m thick, at least one black-coloured layer as light barrier, at least one aluminium layer as vapour barrier, at least one layer serving to increase the resistance to puncturing, at least one layer furthest separated from the paper support to enable the flanges to be heat sealed to the leader and to the core sleeve, and on the other side of the paper support, a layer of a synthetic resin applied by extrusion which imparts a tension to the material to prevent the flanges collapsing inwards.
