  • Patent number: 11655364
    Abstract: [Problem] To provide a thermoplastic resin film excellent in impact resistance, formability and trimmability when forming a container, productivity, and the like, and a thermoplastic resin-coated metal sheet. [Solution] A thermoplastic resin film contains 70 to 97 wt % of a thermoplastic polyester resin component and 3 to 30 wt % of a polyolefin resin component. The polyolefin resin component contains one or more polyolefin resins selected from the group consisting of nonpolar polyolefin resins and polyolefin resins having ester-containing functional groups in side chains thereof. The polyolefin resin component is dispersed, in the thermoplastic polyester resin component, in a fibrous form having an average length of 5 to 300 ?m in a machine direction of the film, an average length of 0.2 to 5 ?m in a thickness direction of the film, and an aspect ratio of 8 or greater.
    Type: Grant

  • Patent number: 11078375
    Abstract: A thermoplastic resin-coated metal sheet obtained by coating at least one surface of a metal sheet with a thermoplastic resin via a polyester type primer, wherein the polyester type primer, if it is in the form of a 10 ?m-thick dry primer sheet, has a breaking elongation in a range of 9 to 200% at a tension speed of 1000 mm/min. and an MEK extractability in a range of 3 to 40%. Without using a special thermoplastic resin-coated film or surface-treated metal sheet, therefore, the cans and can lids can be formed using the thermoplastic resin-coated metal sheet of the invention maintaining excellent and close adhesion during the working, preventing the can body from breaking and the thermoplastic resin coating from peeling at the flange-forming portion during the working, the cans and can lids excelling in dent resistance and economy.
