Abstract
A resin-coated seamless can of the present invention is a resin-coated seamless can formed of a resin-coated metal sheetwhich is produced by coating a polyester resin layercontaining polyethylene terephthalate onto a surface of a metal substrate, wherein the density of a polyester resin layer of a can inner surface side is set to equal to or more than 1.36 at a can barrel upper portion. Further, an infrared dichroic ratio (R1) of the polyester resin layer at the inner surface side of the can barrel portion which is expressed by a following formula (1) is set to equal to or more than 1.1.1=(⊥)/(∥)  (1).In the formula (1), Iw(⊥) indicates an infrared absorption intensity of 973 cmwith respect to polarized infrared rays perpendicular to the can height direction at the can barrel portion, and Iw(∥) indicates an infrared absorption intensity of 973 cmwith respect to polarized infrared rays parallel to the can height direction at the can barrel portion.
