Document Type and Number:
Japanese Patent JP7078178
Kind Code:
B2
Abstract:
The present invention provides a fluororesin-coated body having water repellent oil repellent properties, said fluororesin-coated body being easily assembled by means of an adhesive or heat sealing when assembled into, for example, a package. A fluororesin-coated body which has a non-uniform fluororesin coating film that is formed of fluorine, carbon and oxygen on a base material that is composed of a fibrous substance, and which has a shortest length of uncoated portions of from 5 nm to 10 μm and a coverage per unit area of from 10% to 80%. A method for producing a fluororesin-coated body, said method comprising: a step for providing the surface of a base material that is composed of a fibrous substance with an uneven distribution of carbonyl groups, hydroxyl groups or aluminum atoms, silicon atoms, and copper atoms or nitrogen atoms; and a step for providing a fluororesin film on the uneven distribution.
