Abstract
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.
Claims8
A liquid-repellent heat sealable film comprising:
- 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 bonds to each other, while maintaining their particulate forms, and also bonds to the surface of the substrate to form a projecting and recessed structure, and
- the oxide microparticles are adhered to the surface of the particulate resins in an exposed state without being buried.
A coating agent for applying a resin layer having a heat sealable projecting and recessed structure comprising:
- a solvent;
- and
- particulate resins having heat-sealing property,
- wherein, the particulate resins are particulate deposits caused by insolubilizing the solvent in which heat sealable resins are once dissolved, and are dispersed in the solvent.
