Abstract
An aqueous dispersion composition according embodiments of the present invention includes an ethylene-carboxylic acid copolymer, an anti-blocking agent including a polymer wax included in a content of 5 wt % or more based on a weight of the ethylene-carboxylic acid copolymer, and an aqueous dispersion medium. A peak area corresponding to a melting point of 80° C. or less in a differential scanning calorimetry (DSC) graph is 50% or more. Blocking phenomenon is suppressed using the anti-blocking agent while achieving desired heat seal properties.
