Abstract:
A liquid-repellent structure includes a surface to which liquid repellency is to be imparted; a foundation layer having a surface and disposed to face the surface to which liquid repellency is to be imparted; and a liquid-repellent layer disposed to face the surface of the foundation layer, wherein the foundation layer contains an acid-modified polyolefin, the liquid-repellent layer contains a fluorine-containing resin and particles, and the fluorine-containing resin contains a hydrophilic structural unit having at least one of an amino group and an amide group. A packaging material has the liquid-repellent structure disposed to face a product. The packaging material can also be applied to a product that is a selected one of hand soap, body soap, shampoo, rinse, creams, and cosmetics and that contains a surfactant.
