ABSTRACT:
A flat wrapping or package, e.g., for film sheets, particularly sheets of X-ray film, in which the margins of one web of wrapping material are folded inwardly over the edge margins of a narrower web of wrapping paper with the film sheets sandwiched in between, the contacting web portions are adhered together, and cut edges are sealed together. Each exterior web fold edge is creased along two closely spaced parallel lines spaced apart approximately the thickness of the wrapped film sheet so as to impart to the opposite side edges of the wrapping a generally concave configuration between an upper and lower corner.
