Abstract
A photo negative strip including a sequence of individual photo frames is protected by laminating two slightly narrower strips of transparent protective film onto the opposed surfaces of the photo strip; each protective strip is removably secured to the photo strip by two edge stripes of a pressure sensitive releasable adhesive. The adhesive stripes covers the sprocket holes near the edges of the photo strip, but edge portions of the photo strip are left, uncovered by either protective film, along both outer edges of the photo strip. The preferred protective film is of biaxially oriented polystyrene.
