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. In addition, because these formulations do not contain fluorochemicals, polyethylene or wax the resulting paper products can be recycled and repulped.
