Abstract: A packaging laminate comprising a paperboard substrate for providing a base layer, a tear-resistant polymer layer applied to said substrate, and a heat seal polymer layer applied to said tear-resistant polymer. This laminate structure is particularity useful for blister pack packaging.

Abstract: The invention relates to the papermaking art and, in particular, to the manufacture of paper substrates, paper-containing articles such as file folders, having improved reduction or inhibition in the growth of microbes, mold and/or fungus.

Abstract: The invention relates to the papermaking art and, in particular, to the manufacture of insulation paper facing having improved reduction or inhibition in the growth of mold and/or fungus. This invention also relates to articles of manufacture made from such products such insulation, construction articles, buildings and the like.

Abstract: A laminate useful in the manufacture of ovenable grease resistant food containers, which have the added advantage of good release from the food products, particularly those containing high levels of starch and sugar. The laminate of the present invention includes a substrate, preferably of a paperboard, a layer of grease resistant material, such as polyamide, polyester, polyvinyl chloride, polytetrafluoroethylene, or polyvinyl alcohol, etc., or nylon, a tie layer of low density polyethylene or linear low density polyethylene modified with maleic anhydride, and a food contact release layer comprising a blend of polypropylene and polymethylpentene. In the preferred embodiment, the grease resistant layer, the tie layer and the food contact release layer are coextruded onto a paperboard substrate.

Abstract: A method and apparatus for sterilizing packaging through irradiation with an excimer ultraviolet lamp which may be integrated on a packaging machine. The excimer ultraviolet lamp emits radiation at a substantially monochromatic wavelength within the ultraviolet band of the electromagnetic spectrum. The excimer ultraviolet lamp is composed of a quartz shell containing one of the following gaseous compounds: Ar.sub.2, Kr.sub.2, Xe.sub.2, ArCl, KrCl, KrF or XeCl. The KrCl gas excimer ultraviolet lamp which generates a wavelength of 222 nanometers is of particular interest for the present invention. In one embodiment, the lamp has a central aperture for flowing through a cooling fluid to remove heat from the lamp. If the excimer ultraviolet lamp is integrated on a form, fill and seal machine, the cooling fluid may be the desired contents filled into a container fabricated on the form, fill and seal machine.
