Abstract: A method of making a texture-coated and/or insulation coated container from a flat paperboard blank in which a heat-hardenable liquid polymeric binder texturizing and/or insulating agent coating mixture is applied to one surface of the blank in a pattern of covered and open areas. This coating mixture is subjected to heat to cure the polymeric binder and expand the texturizing and/or insulating agent, optionally treated with moisture, and optionally heated to form the blank into the shape of a container, and the container produced by this method. The containers such as cups, plates, etc., are useful in food service. These containers have a coefficient of static friction which is about 0.2 to 2.0 and over and a kinetic coefficient of friction which is about 0.22 to 1.5.

Abstract: An improved paperboard has been bulk enhanced by retaining a substantial portion of bulk-enhanced additives including expandable microspheres in a suitable distribution within the paperboard. The cellulosic paperboard web has an overall fiber weight (w) of at least 40 lbs. per 3000 square feet and, at a fiber density of 3, 4.5, 6.5, 7, 8.3, and 9 pounds per 3000 square foot ream at a fiberboard thickness of 0.001 inches, has a GM Taber stiffness of at least about 0.00246 w2.63 grams-centimeter/fiber mat density1.63, and a GM tensile stiffness of at least about 615+13.18 w pounds per inch. The high retention of the bulk enhancing additives is believed to result from the incorporation of suitable retention aids. The resulting paperboard has better GM Taber stiffness values and GM tensile stiffness than prior art paperboards. The paperboard also has increased strain to failure and is able to be formed into suitable paperboard containers without loss of integrity.

Abstract: An improved, coated microwaveable paperboard or container useful for forming substantially rigid food containers such as plates, bowls, trays and the like and a process from producing the improved, coated paperboard is provided. The microwaveable paperboard and food containers, at a temperature in excess of 430.degree. F. evolves less than 0.1 milligrams of benzene per square inch, preferably less than 0.04 milligrams. Said paperboard and food containers are produced from a sized paperboard blank wherein a base coat and top coat comprise a mixture of an inorganic pigment and aliphatic copolymers. A base coat comprising an aliphatic latex and a pigment is applied directly to the paperboard, and a top coat comprising the same or different aliphatic polymer latex and a pigment is applied directly to the base coat to form the coated containers. Microwave susceptor layers are coated on the top coat. These containers are used to microwave and brown food at temperatures in excess of 430.degree. F.

A base coat comprising a styrene acrylic latex and a pigment is applied directly to the paperboard, and a top coat comprising a styrene acrylic polymer latex and a pigment is applied directly to the base coat to form the coated plate stock. The improved coated plate stock is characterized by improved grease, oil and cut resistance, improved varnish gloss, enhanced smoothness, and improved printing quality.

Abstract: A color developing material is produced by:a) gradually adding a metal silicate solution to a solution of an aluminum salt which is initially at a pH below 4 until the pH of the resulting mixture is approximately 4, thereby to induce some precipitation and to form a sol;b) gradually adding alkali to said sol to raise the pH to approximately 7, thereby to induce further precipitation and gel the sol or further gel the sol, said gelled sol being a hydrated silica/hydrated alumina composite;c) separating the gel from the aqueous medium and washing the resulting product to remove dissolved salts; andd) drying the washed product and reducing it in particle size.This color developing material is then formulated into a coating composition, applied to a paper base and dried to produce a color developing record material as used in pressure-sensitive (carbonless) copying pape sets.

Abstract: Pressure- or heat-sensitive record material carries hydrated zirconia as a color developer material. The hydrated zirconia may be modified by the presence of compounds or ions of one or more multivalent metals. The record material may be made by forming an aqueous dispersion of hydrated zirconia, either formulating the dispersion into a coating composition and applying the coating composition to a substrate web or introducing the dispersion into a paper making stock and forming a paper web which incorporates hydrated zirconia as a loading, and drying the resulting coated or loaded web to produce the record material.

Abstract: A color developer for use in a pressure- or heat-sensitive record material comprises a particulate amorphous hydrated silica/hydrated alumina composite in which the hydrated silica and hydrated alumina are chemically bound and in which the mean alumina content on a dried weight basis is up to 7.5%, based on the total weight of silica and alumina. The composite may be metal-modified, e.g. with copper.
