Abstract
The present invention provides a heat-sealable water-based coating composition suitable for coating substrates used for packaging of products that contain grease, oil, water, etc. The coating compositions comprise acrylic polymer or copolymer emulsions and melting waxes. The substrates may be formed into containers, such as cups, for example. The coatings provide a barrier that is resistant to the permeation of, for example, grease, oil, water, and other liquids. Furthermore, the coating compositions are compostable.
