Abstract: A shipping and return mailing label includes three parts: (1) a shipping label, (2) a return label, and (3) an intermediate card connected to the two labels by lines of perforations, with the front face of all the parts of the label assembly being exposed as the label assembly is mounted on a backing sheet, so that, for example, bar codes may be directly printed on each of the three parts. The return label is coated with adhesive on its rear side, the card may be free of adhesive, and the shipping label may be of greater extent than the return label and the card, and may have stripes of adhesive located on its three free edges, so that the entire assembly, following printing, may be folded in a Z-shaped manner, and secured to a carton to be shipped.

Abstract: There is provided an apparatus for applying constant pressure to a knife blade for crush-scoring, wherein the knife blade is supported in a substantially frictionless manner and the constant pressure is supplied by a flexible diaphragm acting on a plunger which can move substantially without friction in a pneumatic cylinder.

Abstract: An undersurface imprintable label construction includes at least a translucent film having a layer of adhesive applied to a portion of its undersurface. One or more non-adhesive indicia-receiving zone(s) are on the undersurface of the film to form translucent window(s) on the film. A pressure-sensitive adhesive layer surrounds the window(s) and is releasably secured to a release liner which contains an indicia-transferring layer, such as a reverse carbon paper sheet, facing the undersurface of the film window(s). The undersurface of the film window area being disposed adjacent the indicia-transferring layer in the release liner allows visual indicia to be transferred from the indicia-transferring layer and imprinted on the undersurface of the window area(s) in response to pressure impact being applied to the upper surface of the film window area(s). The undersurface of the film may be partially masked to make the label substantially tamperproof.
