Abstract: A coextruded film having a matte surface layer is prepared by forming the layer from a blend of polyisobutylene and high density polyethylene. The film preferably has a heatseal layer on the other surface. In addition to having low gloss for consumer appeal, the matte surface layer has a medium coefficient of friction for good machinability and excellent heat resistance to facilitate heatsealing. The film is especially useful as an overwrap for packaging consumer products.
Abstract: A liquid dispenser pump including a pump housing, a piston movable within the pump housing, a seal including a resilient wall disposed about the piston, and a reinforcement member for urging the resilient seal wall outwardly into fluid-tight engagement with the pump housing.

Abstract: A resealable packaging enclosure is disclosed which includes a tear path defining an aperture through which products may be extracted from the enclosure, and a resealable closure tab which extends across the tear path. The tear path includes weaker and stronger portions. The stronger portion is more resistent than the weaker portion to forces tending to separate the material comprising the enclosure along the tear path. Thus, the tear path has a variable resistance along its length to forces tending to open the enclosure.
Abstract: A package for use in cooking or heating a food product in a microwave oven which comprises an outer paper container and an inner liner and a microwave interactive heater comprising a coating composition printed onto the surface of a suitable substrate or a selected portion of the outer container or inner liner. The coating composition preferably comprises finely divided carbon, aluminum flake, clay and a binder in a preferred embodiment, a polyester inner liner eliminates the need for an overwrap in packages containing a food product, such as popcorn and an oil.

Abstract: A dispenser cabinet for dispensing sheet material from a wound roll having a groove at at least one end thereof including support members supporting the ends of the roll and a projection extending from at least one of the support members positionable in the groove and frictionally engaging the roll to stabilize the roll and resist rotation thereof.
Abstract: A composition for use in a thermal-sensitive paper coating and a heat-sensitive recording material utilizing the coating, which composition comprises a phenolic developer, e.g., a traditional low speed phenolic having a melting point greater than 120.degree. C., and a pseudo developer. The pseudo developer is combined with the phenolic developer in an amount effective to provide for the formation of homogenous phase when the composition is melted, which phase further solidifies back to a single crystalline phase when cooled.
Abstract: An absorbent towel or tissue product of cellulosic fibers or other fibrous material in continuous roll or strip form is provided with a plurality of lines of weakness, suitably slits or knife cuts, delimiting the edges of individual sheets to facilitate detachment of sheets from the roll without longitudinal tearing of the towel or tissue and maintain bonding of the plies on the roll and in detached sheets.

Abstract: A food package assembly of the type designed to serve the dual function of providing a package for shipment and storage of a prepared food and of microwave heating of the food in a manner producing a browning or crisping effect that is particularly adapted to the needs of foods, such as French bread pizzas and garlic bread, which cannot be crisped in a microwave oven via the use of a single planar microwave interactive crisping layer and which, due to the grease and/or vapor driven out of them cannot be heated in a microwave oven in a closely confined manner without becoming soggy. In accordance with preferred embodiments, a food product is received upon an inner tray member that coacts with an outer package body to cradle the food product so that the adjoining surface thereof will be crisped by a microwave interactive heating layer applied to the facing surface of the inner tray member.
Abstract: When a film consisting of high density polyethylene and about three percent polystyrene is run on an interfolding machine to produce interfolded sheets of the film for use as deli wrap, the film is completely and consistently cut in the machine into sheets that are entirely separated from adjacent sheets. In comparison, sheets made from film consisting of 100 percent high density polyethylene are not consistently completely separated from adjacent sheets.
Abstract: A system for forming first and second spaced circular grooves in a roll produce and including a first and second web cutting assemblies alternately and sequentially movable to form web segments of diminished width along spaced portions thereof which, when wound, form the grooves.
Abstract: A paperboard carton blank consisting of a first panel having side walls connected thereto by scored fold lines formed between a respective side wall and a respective edge of the first panel is provided. The blank further includes a second panel having side walls connected thereto by scored fold lines formed between a respective side wall and a respective edge of the second panel with one of the side walls of the first panel and one of the side walls of the second panel being congruent. The second panel additionally includes a region of weakness formed therein for allowing access to the interior of a formed carton. This region of weakness includes a tab extending from the second panel, at least one uncut line of weakness formed in the second panel and at least one cut line of weakness substantially parallel to the uncut line of weakness and formed in the second panel.

Abstract: Provided by the present invention is a novel magnetic barrier paper comprised of low hysteresis iron powder. Preferably, the iron powder employed has a hysteresis value of not more than about 5 parts per thousand. The magnetic barrier paper of the present invention is particularly applicable to the protection of floppy disks, as well as electronic components, from stray magnetic fields.
Abstract: A disposable microwave browning and crisping package comprising a flexible or semirigid substrate and a microwave interactive layer affixed over one surface of said substrate, said microwave interactive layer, when subjected to microwave energy, operating as a means for converting microwave energy to heat in an amount sufficient to brown or crisp food in heat transfer relationship therewith. The package has non-dispersed, localized microwave permeable means which allows a percentage of the available microwave energy to traverse said package so as to produce dielectric heating within the center of the food product contained herein.
Abstract: Microwave responsive heaters and packages for food products and the like containing the heaters are disclosed in which the heaters consist of a microwave reactive coating composition on a heat stable substrate which is pattern bonded to a surface to be heated by microwave radiation.

Abstract: A catalyst for synthesis of vesicular phenoxy resins is disclosed. The catalyst includes a water-insoluble complex of a hydric phenol and a quaternary ammonium or phosphonium salt of the hydric phenol. Preferably, the hydric phenol is an intermediate of the phenoxy resin being produced. Dihydric phenols, such as sulfonyldiphenol are preferred. The invention further relates to a reaction medium for polymerization of phenoxy resins including the above-described catalyst and a solvent medium capable of dissolving the phenoxy resins and otherwise not interfering with the polymerization reaction. The solvent medium is advantageously free of toxic Methyl Cellosolve.
Abstract: An absorbent pad structure particularly suited for use in a vacuum package for a food product and the like is disclosed as well as its method of manufacture. The composition of the pad is such as to minimize leakage of liquids into the absorbent material during storage and to permit the flow of liquids freely for absorption during cooking of the packaged product. The pad is particularly suitable for use in bacon packages and other food packages containing oils or grease.
