Abstract: An improved process is disclosed for removing nonimpact inks and stickies contaminants from waste paper containing same by repulping the waste paper to form a slurry, adding a densifying agent and an agglomeration agent to the slurry, and subjecting the slurry to treatment with a conical cleaner to remove the inks/stickies. The densifying agent and agglomeration agent addition may be simultaneous or the densifying agent addition may precede agglomeration agent addition and, preferably, is conducted at ambient or greater temperature, at neutral to alkaline pH, and at a pulp consistency (below 18%). Densifying agent addition and agglomeration, followed by passing the repulped waste paper through a conical cleaner, provides improved ink removal over passing the slurry through a conical cleaner without such pre-treatment or with treatment only with densifying agent or only with agglomeration agent.

Abstract: The preparation of packaging material having good moisture barrier properties from a C1S paperboard substrate in a single pass on a printing press is improved by preheating the substrate before application of the moisture barrier coating to the uncoated surface of the substrate. Preheating the substrate improves coating holdout, reduces pinholes and permits the application of a thin film of coating to achieve the desired result.

Abstract: A coated paper product having high gloss and brightness is prepared by a process wherein a paper substrate is coated on at least one side with an aqueous coating formulation comprising an effective amount of a plastic pigment, and finished in a supercalender device containing heated rolls to produce a surface which is comparable to a cast coated surface.

Abstract: A coupon bearing lid component for a container is prepared from a sheet of paperboard, said paperboard having an outer surface with a finished coating for printing graphics and an inner surface on which coupon indicia is printed, the improvement wherein the inner surface of the lid has bonded thereto a polymeric film to cover the printed coupon indicia.

Abstract: The envelope of the present invention is prepared from a single blank of material to include a detachable inside bangtail flap, and a full access rear opening which exposes and automatically elevates the bangtail flap for easy removal when the envelope is opened.

Abstract: A two piece paperboard package that houses a unit dose product on an internal slide card within an outer paperboard shell. This package may have one or more internal or external lock(s) that prevent the slide card from being pulled out without triggering some type of lock release mechanism. This package is focused around providing a child resistant, senior-friendly unit dose package that can be opened and closed numerous times and then finally disposed of.

Abstract: The envelope of the present invention is prepared from a single blank of material to include easy opening means and security features for tamper evident delivery of credit cards, debit cards and other sensitive material. The envelope structure includes a bangtail flap foldably attached to the rear panel of the envelope and folded inside the envelope, a pair of perforated lines located on each side of the rear panel for providing access to the inside bangtail flap, and a separate opening means for the closure flap.

Abstract: The present invention relates to gravure printing ink systems containing improved binder resins. In particular, the invention relates to the use of hydrocarbon/acrylic hybrid resin binder compositions in gravure printing ink formulations.

Abstract: The present invention relates to lithographic printing ink systems containing improved binder resins. In particular, the invention relates to the use of hydrocarbon/acrylic hybrid resin binder compositions in lithographic printing ink formulations.

Abstract: A pelletized cellulosic pulp product is produced from a delignified and bleached paper pulp raw material that is useful as a combustion material. The size, shape, density and glazed outer surface of the pelletized product contributes to controlled combustion of the pellets to support a smoldering burn in use.

Abstract: The present invention relates to ink compositions for use in ink jet printers. More particularly, it relates to the use of hydrocarbon/acrylic hybrid resin compositions in solvent-based, continuous ink jet inks. The ink compositions demonstrate water and rub resistance properties while achieving excellent print quality, jetting properties, storage stability, reliability, and drying times.

Abstract: Authenticatable paper and paperboard products are prepared by printing images such as microdots on one or both surfaces of the paper using a starch containing authenticating solution. The images are not detectable by the human eye, but can be revealed with the application of a standard iodine solution.

Abstract: This invention relates to a height measurement apparatus for determining volume/density of wood chips on a conveyor. Such structures of this type, generally, employ the use of contacts that ride on top of the pile of wood chips in order to more accurately measure the volume and density of the wood chips.

Abstract: The inkjet recording sheet substrate of the present invention comprises a cellulosic sheet support, e.g., paper, having on at least one surface thereof a base coating comprising pigment and binder. The preferred pigment component is a 50/50 mixture of kaolin clay and calcined clay, and the preferred binder component is polyvinyl acetate. This combination of binder and pigment has been found to possess a high absorption capacity for the vehicle of an inkjet ink and good compatibility with ink receptive top coatings applied over the base coat.

Abstract: An envelope for first mailing having a closure flap and an outside bangtail flap which includes a detachable coupon portion. The bangtail flap is larger than the closure flap, is foldably attached to the rear panel of the envelope, and is adhered exteriorly thereto at its side edges, while the closure flap is foldably attached to the front panel of the envelope and is folded over about the bangtail flap and adhered thereto to close the envelope.

Abstract: A continuous loop inductor for an RF-EAS security tag comprises a plurality of discrete, unconnected foil loop segments connected together by conductive ink patches.

Abstract: A non-foil composite laminate for an improved container providing an effective barrier for the containment of essential oils and prevention of losses of vitamin C. The non-foil composite laminate comprises an inner barrier layer of amorphous nylon and outer layers of heat sealable olefin polymer, facilitating manufacture while retaining desirable barrier properties.

Abstract: This invention relates to an apparatus and method for determining paperboard thermal conductivity. Such structures of this type, generally, determine the thermal conductivity of a planar material, such as paperboard or insulating foams. The apparatus is designed to characterize the heat flow from a heated brass cylinder, through a flat paperboard sample, and into another brass cylinder. The brass cylinders are fully insulated, except at the sample interface. During the test, which is in a transient state, the hot mass loses energy, raising the temperature of the cooler mass as the two masses approach an intermediate equilibrium temperature. Knowing that the brass masses are fully insulated, except for the heat transfer interface, and knowing the physical properties of the masses, the only unknown in the mathematical model describing the experiment is the thermal conductivity, k, of the paperboard sample, which enables its determination.

Abstract: This invention relates to calendering systems. Such structures of this type, generally, employ the use of hard and soft nips to provide excellent smoothness without gloss mottle.

Abstract: The present invention relates to a method for producing paperboard packaging (trays, lids, cartons, containers or combinations) with an integral RF-EAS security tag and a procedure for tuning the resonance frequency of the tag.
