摘要:
The resin-coated metal sheet has: a metal sheet; a lower polyester resin layer having 0.03 or smaller plane orientation factor and 5 to 20 μm of thickness, being formed on at least one side of the metal sheet; and an upper polyester resin layer containing 0.1 to 5% by mass of olefin wax, having larger than 0.06 and not larger than 0.15 of plane orientation factor and 0.5 to 10 μm of thickness, being formed on the lower polyester resin layer. The metal sheet assures excellent taking-out performance of the contents also those of low fat and high protein foods, and provides formability and adhesion requested for the container working.
摘要:
The resin-coated metal sheet is composed of: a metal sheet; a lower resin layer containing a hydrophilic copolyester, formed on at least one side of the metal sheet; and an upper resin layer containing a polyester containing a diol component composed of a diol derivative of 1 to 10% by mole of alicyclic compound and 99 to 90% by mole of ethylene glycol, and a dicarboxylic acid component consisting of terephthalic acid, formed on the lower resin layer. The sum of cyclic trimer of alkylene terephthalate existing in the upper resin layer and the lower resin layer is 0.9% or less by mass. Since the manufacture of food cans using the resin-coated metal sheet does not induce white haze phenomenon and retort blushing phenomenon on outer surface of the can even after retorting, the decorative appearance on outer surface of the can is not deteriorated.

A tin-plated steel sheet includes a plating layer containing tin on at least one surface of a steel sheet, and a chemical conversion coating containing P and tin on the plating layer is provided. In the steel sheet, a coated amount of the chemical conversion coating per surface is 1.0 to 50 mg/m2 in terms of P, an atomic ratio Sn/P obtained from the intensity of a P2p peak and that of a Sn3d peak is 1.0 to 1.5, the intensities being measured at the surface using an x-ray photoelectron spectroscopic method, and an atomic ratio O/P obtained from the intensity of the P2p peak and that of an O1s peak is 4.0 to 9.0. The phosphoric acid-based chemical conversion coating of the tin-plated steel sheet can suppress degradation in performance, which is caused by the growth of a tin oxide layer on the surface, instead of a conventional chromate coating.
