摘要： Compositions and methods for rendering a substrate more grease-resistant are disclosed. Treatments, such as aqueous-based treatments and/or emulsions, can be applied to the surface of a substrate, such as paper-based materials, which can be dried to form a treatment layer imparting grease resistant properties. In some instances, the treatment includes an acrylic-based polymer, which can impart grease-resistance, and one or more complementary components (e.g., a polymer and/or oligomer) that can make a layer less brittle (e.g., lowering the Tg of the layer relative to a layer of acrylic-based polymer). Such treatment layers can retain their grease resistance even when creased, allowing the use of such layers in applications such as food processing. Other additives, compositions, and methods are further developed.

摘要： Disclosed herein are grease-resistant compositions that can include a cellulose-based polymer and a complementary material. Such compositions can be applied to substrates, such as paper-based materials, to impart enhanced grease/oil resistance. The complementary material can act to provide the composition with enhanced fatigue resistance relative to layers that solely utilize the cellulose-based polymer, and can preferably have limited leaching from the composition. Examples of complementary materials include polymers, such as poly(vinyl acetate) and poly(vinyl alcohol), plasticizers, and combinations of these materials. Such compositions can be prepared as a treatment formulation or coating material, which can be dissolved or suspended in a solvent. The compositions may also be melted and applied without a solvent. The formulations can be a water-based system, or an emulsion. The films may be applied to paper products as part of the papermaking process, or as post treatments on a coating machine.
