Patent number: 5693385Abstract: Paperboard packaging material is disclosed for use in the manufacture of cartons for products which give off significant odors or aromas. The packaging material is treated to absorb odors generated by the products packaged in the packaging material. For this purpose, the paperboard packaging material is coated on one surface with an odor sorbing coating composition comprising activated carbon dispersed in an aqueous binder system. The odor sorbing coating covers substantially all interior surfaces of cartons formed from the packaging material to provide an effective concentration of activated carbon sufficient to render the contents substantially odor-free.Type: GrantFiled: December 20, 1995Date of Patent: December 2, 1997Assignee: Westvaco CorporationInventor: Christopher J. Parks

Patent number: 5565125Abstract: A printed microwave susceptor includes a paper or paperboard substrate having first and second surfaces. A food contact layer is applied to one surface, and separate thermal insulating layers and microwave interactive layers are applied to the other surface, with the thermal insulating layer being disposed between the substrate and the microwave interactive layer. The microwave interactive layer may be overcoated with a protective layer for abrasion resistance.Type: GrantFiled: October 24, 1994Date of Patent: October 15, 1996Assignee: Westvaco CorporationInventor: Christopher J. Parks

Patent number: 5231268Abstract: Paperboard packaging material for use in the manufacture of containers or inserts for containers for browning and crisping food in a microwave oven is prepared on a printing press. The components of the packaging material include paperboard or an equivalent microwave transparent substrate, a susceptor layer prepared from a printable aqueous susceptor-ink composition, and an intermediate coating applied to the paperboard substrate between the susceptor layer and the paperboard to provide a thermal barrier for the paperboard substrate. The thermal barrier layer may be coated or printed on the paperboard substrate as a substantially uniformly thick layer while the susceptor-ink layer may be pattern-printed on the substrate in varying thickness corresponding to the location of food intended to be packaged in containers prepared from the packaging material. The printed susceptor material is overprinted with a food contact coating.Type: GrantFiled: March 4, 1992Date of Patent: July 27, 1993Assignee: Westvaco CorporationInventors: Roger D. Hall, Christopher J. Parks

Patent number: 5217765Abstract: Paperboard packaging material for use in the manufacture of cartons for browning and crisping food in a microwave oven is prepared on a printing press using an aqueous susceptor-ink composition comprising graphite or conductive carbon black dispersed in a solution of sodium silicate. The susceptor-ink composition is printed on the packaging material in a pattern corresponding to the location of the food intended to be packaged and the food contact surface is overprinted with an FDA approved food contact coating. The use of sodium silicate as the binder for the susceptor-ink composition allows the composition to be printed by gravure or flexographic printing processes and provides hereto unavailable flame retardant properties to the final packaging material.Type: GrantFiled: March 24, 1992Date of Patent: June 8, 1993Assignee: Vestvaco CorporationInventor: Christopher J. Parks

Patent number: 5164562Abstract: A composite susceptor packaging material for use in a microwave oven is disclosed comprising at least two spaced susceptor layers in overlying relation. By using two susceptor layers, the amount of microwave energy reaching food products packaged in such material can be controlled while still heating the surface of the food product to a high enough temperature for surface browning. In this manner the inside of the food product remains moist without drying out. Also disclosed are typical packages prepared from the composite susceptor material.Type: GrantFiled: August 2, 1989Date of Patent: November 17, 1992Assignee: Westvaco CorporationInventors: Todd H. Huffman, Christopher J. Parks

Patent number: 4914266Abstract: Paperboard packaging material is disclosed for use in the manufacture of cartons for heating and browning food in a microwave oven. In accordance with the present invention, a pattern of microwave susceptor is printed on paperboard packaging material using a susceptor-ink composition in the areas where the food is to be browned. The susceptor-ink composition comprises an ink vehicle into which there is incorporated a conductive carbon material such as graphite or carbon black as the susceptor material. The preferred printing process is by gravure, and the printed susceptor is overcoated with an FDA approved food contacting coating.Type: GrantFiled: March 22, 1989Date of Patent: April 3, 1990Assignee: Westvaco CorporationInventors: Christopher J.
