PROBLEM TO BE SOLVED: To provide a packaging material which improves resistance against various organic compounds and can keep stable laminate strength and seal strength even when stored for a long period of rime.SOLUTION: A packaging material for mouth wash has at least a polyester-based resin film layer 1, an anchor coat layer 2 adjacently laminated on the polyester-based resin film layer, and a polyolefin-based resin layer 3 adjacently laminated on the anchor coat layer. The anchor coat layer is a layer formed by applying an aqueous dispersion liquid, which contains a polyolefin copolymer resin containing an unsaturated carboxylic acid or an anhydride thereof and a crosslinking agent but contains no non-volatile aids for aqueous-dispersion preparation, onto the polyester-based resin film layer, and drying the applied aqueous dispersion liquid.SELECTED DRAWING: Figure 1 |
