Abstract: A coating formulation is disclosed that is capable of imparting, onto the treated substrate, an excellent adsorption performance, good print appearance, and enhanced rub-off resistance. Furthermore, the disclosed formulation has good ink stability and offers high quality print appearance throughout long printing runs of high speeding printing applications. The formulation comprises an activated carbon having a particle size of less than 1 micron and a binder, wherein an amount of the binder by weight is in a range of about 30 parts to 100 parts per 100 parts of the activated carbon, and the formulation has a dry basis BET Surface Area of greater than 100 m2/g.

Abstract: The present invention discloses an improved paperboard for use in food or non-food products. The disclosed board utilizes a novel method of applying adsorptive material to packaging paperboard to overcome emissions (by adsorption thereof) of odiferous manufacturing components from the board, as well as any offensive odors emitted by contents of packages made from the board. The disclosed approach utilizes known adsorptive materials, which are applied to the pulp stock in such a manner that it does not negatively impact either the appearance or physical attributes of the finished board.

Abstract: The draft forcing fan system in a vapor adsorber is used to extract spent powdered or granular adsorbent from the contacting column by blocking the normal air route intake and discharge ducts. Auxiliary fittings mounted on the intake and discharge ducting facilitate temporary duct connections with a conveniently sized vacuum receiving cannister. In this mode, the fan which forces draft through the adsorption unit operates as a vacuum sweeper. A manually manipulated sweeper wand connected to the vacuum cannister is used to draft the spent adsorbent charge from the contacting chamber into the cannister for removal, regeneration or disposal.
