In web/ink-jet operations in which ink jet data is over-printed on forms prepared by offset litho, undesirable interactions between the surface size and litho-fountain are controlled by use of a PCC basesheet having a size press coating of starch and alum, the alum amount being at least 0.75% by weight.

A fluid material application system is provided with an application deck for applying a fluid material that includes printing ink, adhesive or coating, a source of fluid material, a source of heat transfer liquid, and a heat exchanger. The heat exchanger includes a tube-in-hose ink heat exchange element having a fluid material carrying seamless tube located within a hose. The hose is adapted to be connected to a heat transfer fluid source so that a heat transfer fluid flows around the fluid material carrying tube to control and maintain the temperature of the fluid material in the tube at a generally constant temperature. The elongated heat exchange element may possess a winding type of configuration (e.g., it may be coiled or helically wound or may be laid out in a serpentine path) to define a winding flow path for the fluid material and the heat transfer fluid, and may be located within an enclosing structure to define an overall compact heat exchanger.

An insulating container comprising a container body having at least one side wall and a bottom wall with the side wall including a base layer, an insulating layer on at least a portion of the base layer and a printed pattern, mineral oil application or combination thereof on at least a portion of the surface of the insulating layer is disclosed wherein a thickness of the insulating layer is controlled by the printed pattern and/or mineral oil on the selected portion of the insulating layer. Similarly, stock material incorporating the present invention includes a base layer, an insulating layer formed on at least a portion of the base layer and a printed pattern printed on and or mineral oil applied to the insulating layer is disclosed wherein the thickness of the insulating layer is again controlled by the printed pattern and/or mineral oil on the portion of the insulating layer. The container may be formed of pre-manufactured stock material, by unexpanded stock material or by forming a container body from a paper or paperboard material including a bottom wall and at least one side wall, coating at least the side wall portion of the container body with a thermoplastic synthetic resin film and subsequently printing a pattern on the surface of the thermoplastic synthetic resin film. Once formed, the container is heated at a predetermined temperature for a predetermined time period sufficient to form a heat-insulating layer on the outer surface of the container by expanding the thermoplastic synthetic resin film. The expansion of the thermoplastic synthetic resin is controlled by a thickness of the printed pattern placed thereon, the mineral oil coating or a combination thereof.

A heat insulating paper cup with improved insulation in areas where printed matter exists. The printed matter is applied using a water-based alkyd or epoxy ink. In one embodiment the cup can include a body member having an inside surface and an outside surface, and a bottom panel member having a upper surface and a bottom surface. The body member is coated on its outside surface with a foamed synthetic resin, and on its inside surface with an unfoamed synthetic resin. The bottom panel member is optionally coated on its upper surface with a foamed or an unfoamed synthetic resin. The body member and bottom panel member are oriented and joined to form a seal at an interface between a portion of inside surface of the body member and a portion of the upper surface of the bottom panel member. The printed matter is applied prior to foaming of the synthetic resin on the outer surface of the cup.

Method for fabricating heat insulating paper cups

A patterned metal foil/substrate laminate wherein the pattern is formed by laminating a sheet of metal foil to a substrate by applying an adhesive between the metal foil and substrate in a predetermined pattern which defines areas where adhesive is present and areas where no adhesive is present, cutting the metal foil, as by rotary die cutting or laser cutting, in a pattern which corresponds to the boundaries of the adhesive-containing areas and removing the areas of metal foil which are not adhesively adhered to the substrate. Particularly where the laminate is intended for microwave packaging, the laminate further includes a sheet of barrier layer material, preferably polymer film, laminated to the patterned metal foil layer. The polymer film layer-containing laminate can be formed into a container for packaging food intended for heating in a microwave oven, the container having at least one section, corresponding to the areas of the laminate from which metal foil was removed, that is substantially transparent to microwave energy and at least one section, corresponding to the foil-containing areas of the laminate, that is opaque to microwave energy for shielding food adjacent to the opaque section. Preferably, the metal foil is aluminum foil, desirably unannealed aluminum foil, and the substrate is selected from paper, coated or uncoated paperboard and polymer film.

Patterned metal foil laminate and method for making same

A present invention provides a microwave interactive laminate and a process for brush deactivation of such a laminate. A film, coated with a microwave interactive layer is provided. A desired portion of the microwave interactive layer is coated with a mask layer and the entire assembly is then exposed to abrasion means. The coated and un-coated areas are subjected to the application of mechanical forces to form discontinuities in the microwave interactive layer. That portion of the microwave interactive layer that was coated remains interactive with microwave radiation and is a heating area while the un-coated area is deactivated.

Metalized microwave interactive laminate and process for mechanically

A patterned microwave interactive element and laminate including a patterned microwave interactive element for use in forming food packaging materials that may be employed to store and subsequently cook the food stored therein are provided. The pattern of the microwave interactive element is selected to focus the heat generated to predetermined areas of the food contained in the packaging. Areas where the microwave interactive element has been deactivated may be formed by a variety of methods, such as by demetallization, by the application of an inactivating chemical, by mechanical means and the like, to create a preselected pattern of inactive areas relative to the active areas, thereby controlling the temperatures produced in different sections of the packaging material. Optimum browning and/or crisping of the microwave heated food product may be achieved by selecting a pattern of microwave interactive and inactive areas tailored to specific food products.
