Abstract: A support for a photographic printing paper comprising (a) a polyolefin synthetic resin layer containing a white inorganic filler, (b) an opaque layer of a synthetic paper or a synthetic resin film, (c) a synthetic resin layer having a greater stiffness than the polyolefin synthetic resin layer and (d) a synthetic paper or a synthetic resin film layer on which writing is possible, wherein the relative thickness of the polyolefin synthetic resin layer (a) is not more than about 20% of the total thickness of the support and the relative thickness of the synthetic resin layer (c) having greater stiffness than the polyolefin synthetic resin layer (a) is not less than about 15% of the total thickness of the support.

Abstract: An opening means for containers and packages comprising a sheet containing at least one crystalline thermoplastic high molecular weight resin layer, the resin layer being partially uniaxially oriented, and a tab integrated with the sheet to be pulled up in the uniaxially oriented direction, the sheet being applied to that area or part of the containers and packages to be opened.
