    Abstract: ABSTRACT The present disclosure relates to coatings and coating compositions that are substantially free of bisphenol A (BPA) and similar compounds, which help reduce or minimize flavor loss associated with foods or beverages stored in contact with the coating compositions. In one aspect, the composition can include the reaction products of an intimate mixture of cyclic ether resins and acrylate resins, which provides a unique cross-linked and interpenetrating network of polmers.

    Abstract: A method for decreasing acetaldehyde content of melt processed polyester comprising combining with polyester an organic additive compound that scavenges acetaldehyde from polyester. The organic additive compound comprises at least two component molecular fragments, each component molecular fragment comprising at least two hydrogen substituted heteroatoms bonded to carbons of the respective component molecular fragment. Each component molecular fragment is reactive with acetaldehyde in the polyester to form water and a resulting organic compound comprising an unbridged five or six member ring including the at least two heteroatoms. The reduced acetaldehyde content polyester is particularly useful for making containers such as for packaging beverages.

    Abstract: Coatings are provided to give polymeric structures a top coat that improves the gas barrier properties of the structure while enhancing the water resistance of the top coating and while improving the adhesion of the top coat to an underlying layer of the structure. These top coat compositions comprise an organic barrier coating material in combination with an epoxide additive which enhances the water resistance, adhesion, gas barrier, or a combination thereof, of the top coat barrier layer. Multilayer structures having this top coat are also provided, particularly in the form of containers for food and beverage packaging.
