Abstract

This invention relates to a water based composition for coating paper, particularly paper based food and confectionary packaging and to a method of manufacturing the composition. The invention includes paper products coated with the composition, particularly paper food and confectionary packaging adapted to replace hot wax coated packaging. The composition comprises 10 to 30% by volume of an aqueous film forming heat-seal acrylic emulsion and 15 to 40% by volume of an aqueous ethylene acrylic copolymer resin in a blend vehicle constituted by an aqueous polyethylene emulsion together with one or more additives, in which the acrylic emulsion is a styrene acrylic resin and in which the additives include one or more of an emulsion stabiliser, an anti-foaming agent and a lubricant that is formulated to provide slip and anti-blocking characteristics.
