A surface-treated steel sheet including a tin-plated steel sheet having a tin plating on a steel sheet; a tin oxide layer formed on the tin-plated steel sheet and containing tin oxide as a main component; a composite oxide layer formed on the tin oxide layer and containing phosphoric acid and aluminum as main components; and an aluminum-oxygen compound layer formed on the composite oxide layer and containing an aluminum-oxygen compound as a main component, wherein the tin oxide layer has a thickness of 8 to 20 nm.

Surface-treated steel sheet, metal container, and method for manufacturing surface-treated steel sheet

There is provided a surface-treated steel sheet () comprising: a tin-plated steel sheet () obtained by tin-plating a steel sheet (); a phosphate compound layer () containing tin phosphate formed on the tin-plated steel sheet (); and an aluminum-oxygen compound layer () on the phosphate compound layer (), a main constituent of the aluminum-oxygen compound layer () being an aluminum-oxygen compound; wherein, when the 3dspectrum of tin in the aluminum-oxygen compound layer () is determined using an X-ray photoelectron spectroscopy, the ratio of the integration value of the profile derived from tin oxide to the integration value of the profile derived from tin phosphate (tin oxide/tin phosphate) is 6.9 or more.

[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 &#x3bc;m in a machine direction of the film, an average length of 0.2 to 5 &#x3bc;m in a thickness direction of the film, and an aspect ratio of 8 or greater.
