Abstract
A fluoropolymer resin coated member in which the fluoropolymer resin layer has been improved in wear resistance and peeling resistance. When the coated member is used to form a mold for polyester container molding, part of a polyester resin or an oligomer ingredient or additive contained in the polyester resin is prevented from depositing on the mold surface. And a polyester container with excellent luster and transparency can be manufactured. The fluoropolymer resin coated member () comprise a foundation () and a fluoropolymer resin layer () formed thereon, the foundation () having a surface roughness of 2 to 10 degree in Root-mean-square slope of profile, the amount of the fluoropolymer resin of the fluoropolymer resin layer () being 0.5-8.5 g/m, and the surface roughness of the fluoropolymer resin layer being 5 degree or less in Root-mean-square slope of profile Δq2. The metal mold for forming polyester resin container can be reproduced in such a manner that amorphous fluoropolymer resin layerapplied on the hard surface of foundationof the metal mold for forming polyester resin container is removed by abrasive to obtain mirror finish, then a new amorphous fluoropolymer resin layeris applied on the surface of foundation
