Abstract
A polymer composition is disclosed and consists essentially of 100 parts by weight of an ethylene-alkyl acrylate copolymer and about 1 to 15 parts by weight of an ester formed from a rosin acid and ethylene glycol, propylene glycol, or glycerine. The polymer compositions have a lower heat sealing temperature than the ethylene-alkyl acrylate copolymer contained therein.
