<p>PROBLEM TO BE SOLVED: To provide an anchor coat agent for producing a packaging material by extruding polypropylene resin and laminating on a base material such as a thermoplastic resin film, in which, even when line speed of the extrusion laminate is increased, adhesion between the base material and the extruded polypropylene resin layer is excellent, and the acquired packaging material is excellent in content resistance, and a PP odor is suppressed.SOLUTION: Provided is the anchor coat agent for polypropylene resin extrusion laminate, which is an aqueous dispersion including acid-modified polypropylene resin and an aqueous medium, in which a polypropylene component of the acid-modified polypropylene resin is a homo-polypropylene formed of an isotactic structure.</p> |
