摘要： A wet coating composition useful for coating a cellulosic fiber-based substrate is provided. The composition includes two aqueous emulsions. The first emulsion includes an oxidized paraffin/polyethylene wax and the second emulsion includes an ethylene/acrylic acid copolymer wax, ethylene/acrylic amide copolymer wax, ethylene/acrylic acid/acrylic amide copolymer wax or a mixture thereof. The oxidized paraffin/polyethylene wax has a surface energy less than or equal to 25 mN/m being substantially dispersive energy. The wet coating composition when dried forms a coating having a surface energy ranging from 20 to 60 mN/m being the sum of dispersive and polar energies. A process for treating a cellulosic fiber-based substrate with the wet coating composition, a substrate coated and articles including the coated substrate are also described. The process involves a heating step to allow migration of the coating towards a core of the cellulosic fiber-based substrate.

摘要： A composition that includes plant derived wax having a melting point of at least 70° C. can be used to waterproof cellulose based materials like paper and board. Suitable waxes include sugarcane wax and rice-bran wax. A surfactant such as stearic acid improves the adhesion of the composition to the underlying material. The resulting waterproof laminate can be economically recycled. Hot beverage cups made from the laminate are waterproof and recyclable without first being separated into components. Coffee pods and drinking straws that are waterproof and recyclable are manufactured with the waterproof laminate.

摘要： Latent dispersants were made by the hydrogenation of an alkyl ketene dimer, alkenyl ketene dimer, or ketene multimer. Adding the latent dispersant to paper or paperboard increased its resistance to water and water vapor while maintaining recyclability and repulpability. Additionally, provided is a method for increasing the repulpability of a wax coated paper or paperboard. Dispersants made by the hydrolysis of the alkyl ketene dimer, alkenyl ketene dimer, and ketene multimer are also described.

摘要： The present invention relates to an acrylic pressure-sensitive adhesive composition containing an acrylic polymer and a tackifier obtained by acid modification of a tackifier resin inherently free of an acid component; a pressure-sensitive adhesive tape including a substrate made of a film comprising an olefin polymer or a thermoplastic resin containing a carbonyl oxygen atom in the molecular skeleton, and the acrylic pressure-sensitive adhesive composition on at least one surface of the substrate, and the like. The invention provides an acrylic pressure-sensitive adhesive composition having high adhesive strength (particularly initial adhesive strength) to an adherend having lower polarity, such as an olefin polymer heretofore been considered poorly adhesive, wherein degradation of the adhesive strength after heating and preservation has been suppressed, as well as a pressure-sensitive adhesive tape comprising the composition. The pressure-sensitive adhesive tape of the present invention is also useful for binding.

摘要： Recyclable and repulpable coated paper stock, preferably for use as ream wrap, comprising a substrate coated on at least one surface with a base coat and at least one additional coat over said base coat. Both coats are water based dispersions of a polymer selected from the group consisting of acrylic polymers, acrylic copolymers, polyvinyl acetate, polyvinyl alcohol, ethylene-vinyl acetate, polyvinyl chloride, styrene butadiene copolymers, polyvinylidiene chloride and its copolymers, or starch. The wax free coating forms a pin-hole free continuous film on the substrate which is resistant to water and water vapor. The invention also includes processes for making and recycling the invented coated paper stocks.
