    摘要: The present invention is a liquid-repellent film that exhibits an excellent liquid repellency, and a packaging material of which a surface is formed of the same. The liquid-repellent film comprises: an undercoat part (90) formed unevenly on the substrate surface by microparticles (70) and a thermoplastic resin (80); and a topcoat part (60) having: (i) a minute uneven structured part that includes hydrophilic microparticles (20) having a smaller particle size than the microparticles (70); (ii) a liquid-repellent moiety (40) that bonds to the surface of the minute uneven structured part; and (iii) a binder resin (50) that is present between the surface of the undercoat part (90) and the minute uneven structured part, and is distributed to cover the bonding part of the minute uneven structured part and the liquid-repellent moiety (20).

    摘要: The present invention is a liquid-repellent heat sealable film that is excellent in liquid repellency and heat-sealing property, and has durability. The film comprises: a resin layer applied and formed on at least one surface of a substrate; and a large number of oxide microparticles adhered to the surface of the resin layer, wherein, in the resin layer, a plurality of heat-sealable particulate resins is bonded to each other, while maintaining their particulate forms, and is also bonded to the substrate surface to form a projecting and recessed structure, and the oxide microparticles are adhered to the surface of the particulate resin in an exposed state, without being buried.
