  • Patent number: 9580869
    Abstract: A process is disclosed for topically applying additive compositions to planar substrates, such as tissue webs. In one embodiment, the process is designed to apply relatively high viscous compositions to base sheets at high speeds in a manner that prevents the additive composition from penetrating into the sheet. The additive composition having the relatively high viscosity can be applied to the base sheet in one embodiment using an offset gravure printing process. The applicator roll includes a pattern of raised elements. The raised elements define a surface having at least one dimension that is less than 500 microns. The raised elements are also spaced closely together in order to prevent fiber buildup on the roll during relatively fast processing speeds.

    Abstract: Polymeric formulations which contain aqueous dispersions of acrylic monomers and copolymers and modified polyethylene terephthalate resin are disclosed which are useful as a coating system or treatment for imparting water, oil and grease resistance to underlying cellulosic substrates. The formulations do not contain any fluorochemicals, polyethylene or wax. Moreover, the formulations provide water, oil and grease resistance properties that are an improvement in the art to known coatings and treatments which contain polyethylene and or wax for water, oil and grease resistance. These coatings can also impart improved anti-wicking properties over the existing art. These formulations have interest as they contain components that are permitted to come into direct contact with food products. Therefore, the formulations of the present invention are ideal for use as coatings for paper and paperboard, including paper packaging such as that utilized in food wrappers, food containers, food receptacles, etc.

  • Publication number: 20130231428
    Abstract: The invention relates to a composition which, when mixed with a polymer composition, allows for the formation of a continuous and cohesive film. The film is characterized in that it provides water, grease and oil resistance, provides a water vapour barrier and can used as wax replacement treatment and a top coat for flexible packaging, but also on other substrates. This film is formed at a very fast set speed without the need of thermal energy. The composition contains i) a salt of one or more of myristic, palmitic and stearic acid; and preferably also ii) a C9-C18 fatty acid complex of a metal ion, said metal ion having an oxidation state of at least 3. The invention also provides processes and coated substrates.
