Abstract: Tamper-evident electric paper is made of two sheets of electric paper bonded together, the bottom sheet of which includes a pattern. Any attempt to erase a writing on the top sheet of electric paper results in the pattern on the bottom sheet of electric paper being erased. Therefore any tampering by erasure of a writing on the tamper-evident electric paper is revealed by the absence of a portion of the pattern on the bottom sheet of electric paper. Single sheet tamper-evident electric paper has a complex pattern, such as an encryption, printed on a single sheet of electric paper. Any attempt to erase a writing on the electric paper also erases a portion of the encryption, thereby providing evidence of tampering.

Abstract: This invention pertains to methods of defining and developing first and second sets of periodic features of a web wherein neither the first set or second sets of features is readily sensed as a reliable registration element against which the location of the other can be registered. The method comprises applying registration images along the web, leading edges of the images being consistent with sufficient acuity and measurable intensity of image, and having suitable outline, to be discerned by a registration sensor. The registration images can thus serve as registration marks for determining positions along the length of the web. The web features are applied periodically along the web, forcing registration of the first set of web features to the registration images. The trim material is removed from the web, defining and developing the cut-outs in registration with ones of the first set of web features.

Abstract: A storage bag formed from a thermoplastic film includes a pad secured to the inside bottom thereof. The pad is disposed adjacent the bag material at or near the bottom by one or more strips of material extending across the pad. Each strip has an intermediate portion extending over the pad and two opposed portions each affixed on opposite sides of the intermediate portion to the bag material. If a single strip is used to secure the pad, the single strip has a sufficiently narrow width that the pad extends preferably beyond the strip on opposite sides of the intermediate portion. If two strips are used to secure the pad, each strip is disposed at a spacing to the other in extending over the pad. Thus, in either case at least part of the pad is exposed and uncovered by the strips of material.

Abstract: A process for making an internally-reinforced bag assembly includes formation of an outer bag body with a plurality of longitudinally oriented, laterally spaced pleats or tucks therein. An inner reinforcement layer is applied to the outer bag body after formation of the pleats, whereby the inner layer spans and overlaps each of the pleats. An apparatus embodying the present invention effects bag formation in this fashion. Advancement through the forming apparatus effects formation of the outer web into a gusseted tube, and formation of a square bottom seal. The completed bag assembly includes the inner reinforcement layer, which is dimensioned to define a circumference which is less than a circumference defined by the bag body. The resultant bag assembly resists bulging and deformation under the influence of particulate, granular, or other flowable products packaged therein.
