Abstract: An adhesive tape comprising a backing and a layer of adhesive on the backing. The backing comprises a biaxially oriented substrate which comprises an isotactic polypropylene composition. The tapes and backings of this invention can be severed readily using commercial tape dispensers having metal or plastic cutting teeth to produce cleanly serrated cut edges on the tape. The biaxially oriented substrate is preferably made from a resin comprising an isotactic polypropylene homopolymer having a melt flow rate greater than 8 grams/10 minutes, more preferably greater than 12 grams/10 minutes, and still more preferably greater than about 20 grams/10 minutes.

Abstract: The invention is a mating film. The mating film comprises a base sheet having a first major surface. A plurality of generally parallel ridges project from the first major surface. The ridges comprise a stem portion attached to the base sheet and generally upright from the base sheet. A head portion of each ridge is spaced from the first major surface and extends generally laterally from the stem portion so as to define a lateral distance. The center of each stem portion of each ridge is spaced from the center of each adjacent ridge stem portion by a distance greater than about 2 times lateral distance defined by the head portion.

Abstract: A W-stacked pads of tape strips dispensable at a low peel angle, comprising a plurality of superimposed tape strips longitudinally reversed so as to align the first end of each tape strip with the second end of an immediately overlaying and an immediately underlying tape strip.

Abstract: Methods for adhering an article having an electret charge to a substrate are disclosed. The methods include a step in which a charging material is used increase the adhesion of the article to the substrate.

Abstract: A stencil comprises an electret film, wherein the film has at least one perforation having a perimeter that defines an area, and wherein the area is greater than or equal to about one square centimeter. Methods of marking a substrate using stencils of the present invention are also disclosed.

Abstract: The invention provides a method for imparting an image to a substrate that includes imparting an image to an image transfer sheet having an image receptive layer releasably attached to a carrier sheet, wherein the imaged side of the image transfer sheet is the side containing the image, and the non-imaged side is the opposite side, contacting the imaged side of the image transfer sheet with the substrate, applying localized pressure to the non-imaged side of the image transfer sheet, and removing the carrier sheet wherein removal of the carrier sheet imparts the portion of the imaged image receptive layer, in a discontinuous fashion, where localized pressure was applied to the non-imaged side of the image transfer sheet.

Abstract: A stacked pad of large adhesive tape sheets containing a plurality of superimposed tape sheets formed from a substrate with an area of differential release, which extends less than the full length and width of the substrate. The second major surface of the substrate includes a layer of an adhesive. Sequential tape sheets in the pad are configured and arranged with the area of differential release alternating between first and second corners of the sheets with the adhesive layer of each tape sheet is releasably adhered to an adjacent tape sheet at a higher adhesion level, except for the area of differential release which adheres to an adjacent tape sheet at a lower adhesion level.

Abstract: Various systems and methods of handling items such as files are disclosed, including systems and methods for polling RFID-tagged items while they are stored in storage areas.

Abstract: Adhesive tape backings comprising isotactic polypropylene blended or mixed with at least a second polyolefin. The backing is biaxially stretched so as to provide a film having any one or a combination of the following preferred characteristics: A. Puncture energy up to 20 J/cm2 when 2.54 cm wide samples are tested by the method set herein, or up to 90 J/cm2 when 1.27 cm wide samples are tested by the method set out herein. B. Puncture elongation up to about 1.3 cm when 2.54 cm wide samples are tested by the method set out herein, or up to 2.0 cm when 1.27 cm wide samples are tested by the method set out herein. C. Tensile strength up to 140 MPa in the MD. In a preferred embodiment, the second component comprises polyethylene, polybutylene, or syndiotactic polypropylene.

Abstract: A laminar article comprising a blend of at least one olefin polymer and at least one ethylene-vinyl alcohol copolymer. If desired, a compatibilizer may also be included in the blend. The melting point of the ethylene-vinyl alcohol copolymer having the highest melting point in the blend is at least 5.degree. C. below the melting point of the olefin polymer having the lowest melting point in the blend. The melt index of the olefin polymer can be higher than, lower than, or equal to the melt index of the ethylene-vinyl alcohol copolymer.
