Abstract
A composition includes a polyolefin dispersion of one or more polyolefins having a melting point of 80° C. to 130° C. and having an average particle size of from 0.5 microns to 5 microns; and a healing dispersion comprising an ethylene methacrylic acid copolymer (“EMAA”) having a melting point of 80° C. to 120° C. and having an average particle size of from 0.1 microns to 1 micron, wherein the EMAA copolymer is from 0% to 40% neutralized, further wherein a weight ratio of the EMAA to polyolefin in the composition is from 1:100 to 10:100.
