Abstract: Disclosed are single and multi-layer films having low haze and low density properties, comprising at least one polymeric layer and at least one density reduction agent, wherein the film has a haze ?35% and a density (D) of at least 1% lower than the density of the polymer. The density reduction agent may be added to, for example, a core layer, one or more tie layers, or a core layer and one or more tie layers. Processes for the manufacture of these films, and the use of these films as labels and packaging products are disclosed.

Abstract: An arrangement for generating a classification code for a fingerprint having a pattern of ridges, the ridges having a plurality of reference features, which includes overlaying the intersection of a pair of cross-hairs at a first one of the reference features. A line is overlaid from a second one of the reference features to the first reference feature. The cross-hairs are oriented so that the line bisects a quadrant of the cross-hairs. The ridges crossed by predetermined portions of the cross-hairs are counted to generate the classification code.
