Abstract: Permanent surface modification of polypropylene nonwoven fabrics is achieved through electron beam radiation induced chemical bonding. The electron beam energy levels suitable for such chemical bonding are between about 5 KeV to about 110 KeV at the surface of the fabric facing the electron beam radiation source. At these energy levels, chemical bonding, control of electron beam penetration and the formation of free radicals in the polypropylene nonwoven fabrics are achieved. Control of electron beam penetration produces free radical formation and chemical bonding at selective levels within the fabric as well as bonding of different chemicals asymmetrically to the same fabric with minimal, if any, loss of polymer fabric strength.

Abstract: A process for making an opaque, oriented polymeric film structure and the resultant film structures. The process comprises preparing a melt containing a crystallizable polymeric matrix material at a temperature of at least above the melting point of the polymeric matrix material and thereafter forming the melt into a sheet containing molten polymeric matrix material. The sheet containing molten material is then cooled to form a sheet containing amorphous polymeric matrix material and crystallites of the polymeric matrix material. The sheet while containing the amorphous polymeric matrix material is then formed into a film by stretching the sheet in at least one direction so as to form voids adjacent to at least some of the crystallites and thereby impart opacity to the film.

Abstract: A double sided tape has repositional with adhesive associated with a first face. The tape may be in the form of a roll, and the adhesive on the second face may be either repositional or permanent. In order to facilitate rolling, a release liner is provided on one of the adhesive faces. The tape may have perforations, notches, or slits along its length to facilitate detachment of predefined lengths of the tape, as from a dispenser. A tie coat may be applied to each of the faces of the substrate before the adhesive is applied. One face of adhesive can be readily applied to one object (e.g., a shelf or a piece of paper), while the repositional adhesive is then available to removably attach that object to another object (e.g., another piece of paper).
