  • Fluropolymer resin coated member, a metal mold for forming polyester resin container made thereof and reproducing method of said metal mold
    Patent number: 8043677
    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 (1) comprise a foundation (10) and a fluoropolymer resin layer (20) formed thereon, the foundation (10) 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 (20) being 0.5-8.5 g/m2, and the surface roughness of the fluoropolymer resin layer being 5 degree or less in Root-mean-square slope of profile ?q2.

  • Printing method for printing on can barrel
    Patent number: 6550389
    Abstract: A printing method for printing an ink layer on a can barrel. The method includes picking-up a bright ink containing at least one bright pigment having an average particle size of from 5 to 25 &mgr;m selected from the group consisting of aluminum flake and fine particulate coated pearl pigment from an engraving roller, feeding the picked-up ink to a printing plate directly or via a rubber roller, and applying the ink on the printing plate to a can barrel via a blanket wheel.
