Abstract: Pressure sensitive adhesive compositions are disclosed comprising acrylic emulsions that are emulsion polymerization products of (a) a monomer mixture comprising, based on the total weight of monomers in the monomer mixture, from 50 to 99 weight percent 2-ethylhexyl acrylate and from 1 to 50 weight percent an unsaturated monomer, (b) a surfactant, and (c) an initiator. Methods for preparing pressure sensitive adhesive compositions are also disclosed. Food contact articles comprising the disclosed pressure sensitive adhesive compositions are also disclosed. In some embodiments, the disclosed food contact articles have an overall migration of less than 25 mg/dm2, as measured in accordance with EN 1186, or less than 10 mg/dm2, as measured in accordance with EN 1186.
