Packing for single films

Claim 1

A packing for loading a plurality of flat rectangular single non-X-ray films which have the same emulsion orientation directly into a daylight-loading camera cassette comprising a plurality of single films in a stack, each having a leading edge and a trailing edge, each of leading edges being cut straight and free of cut-away portions. a foil envelope arrangement which surrounds the stack in a light-proof and climate-proof manner and has an easily weldable smooth plastic material foil as an internal layer, an aluminum foil as a central layer, an external layer, and has a plurality of weld seams which weld the foil arrangement together, of which two weld seams extend in parallel to each stack edge and at least one weld seam extends perpendicularly thereto and meets said two weld seams, the foil envelope arrangement is dimensioned to enclose and embrance the stack under normal pressure conditions tightly enough to maintain the coherence between the single films of the stack and to retain the films in their stacked orientation one above the other and to substantially limit the sideways movement of the stack but loosely enough to permit relative movement of the stack and the envelope perpendicularly to said two weld seams, the foil arrangement having two short gussets, one lying before the leading edge of the stack and one lying behind the trailing stack edge, substantially limiting the lengthwise movement of the stack. the foil arrangement providing a holding strip not accessible to the stack the foil arrangement providing a pull strap not accessible to the stack extending to the other of said two weld seams and being substantially longer than the holding strip, the external layer being a smooth tension-proof plastic material foil.
