Abstract: A coating is provided for enhancing low temperature heat sealability and providing high hot tack to polymeric substrates. The coating is water-based and includes a dispersion of a copolymer of ethylene and acrylic or methacrylic acid, and a compatible adhesion enhancer which is an aliphatic polyurethane emulsion. The coating may also include additives such as wetting agents, matting agents, antiblocking agents, and tackifying resins. The coating may be applied to a variety of polymeric substrates and may be heat sealed to itself, or to polymeric substrates, cellulosic substrates, and metal substrates.

Abstract: A primer coating is provided for use on polymeric substrates to enhance adhesion of liquid toner to the substrates for printing in an electrophotographic printing device. The primer coating is water-based and includes a dispersion of a copolymer of ethylene and acrylic or methacrylic acid, and a compatible adhesion enhancer selected from an aliphatic polyurethane dispersion, a hydrogenated hydrocarbon rosin or rosin ester dispersion, and an amorphous acrylic polymer dispersion. The coating may also include additives such as wetting agents, antiblocking agents, matting agents, and waxes. The primer coating may be applied to a variety of polymeric substrates including polypropylene, biaxially oriented polpypropylene, polyethylene terephthalate, and polyvinyl chloride.

Abstract: A water-borne resin composition which can be readily applied to treat fibrous substrates at ambient temperatures and which provides enhanced strength and rigidity for the substrate under both ambient as well as wet or humid conditions is provided. Preferably, paper substrates treated with the resin are capable of being repulped and recycled.

Abstract: The present invention relates generally to a hot melt wax coating composition containing at least one chemical compound which is either itself capable of acting as a latent dispersant for the coating or capable of being chemically modified so as to act as a dispersant for the coating, within an aqueous environment, thus rendering the hot melt coating more readily redispersable. The present invention also relates to a coated paper product using such coating which renders the coated paper more readily repulpable (recyclable) with standard paper mill equipment. Other related aspects of the present invention include a method of coating paper with the novel coating composition and a method of repulping such coated paper.

Abstract: A hot melt wax coating composition and hot melt wax coated paper product are provided which coating contains at least one chemical compound which is either itself capable of acting as a latent dispersant for the coating or capable of being chemically modified so as to act as a dispersant for the coating, within an aqueous environment, thus rendering the hot melt coating more readily dispersable from the coated paper. The coated paper product is repulpable using standard paper mill equipment.

Abstract: A non-skid surface composition for paper and paperboard products which is easy to apply and to clean up, which is noncorrosive and nontoxic, and which increases the coefficient of friction on the surfaces of products coated with the composition is provided. The composition does not interfere with the ability to recycle the paper to which it has been coated. The non-skid surface composition is applied as an aqueous suspension of colloidal silica or alumina with glycerine to the surfaces of a paper product.

Abstract: A packaging material has a continuous interlaminate conductive coating to shield against electrostatic potential. The interlaminate position protects the physical integrity of the coating and avoids multiple problems and expenses associated with surface coatings. A container having closed faces is formed from the material to form a Faraday cage.
