Resin-coated seamless can |
摘要 |
A resin-coated seamless can of the present invention is a resin-coated seamless can formed of a resin-coated metal sheet 1 which is produced by coating a polyester resin layer 3 containing polyethylene terephthalate onto a surface of a metal substrate 2, 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. R1 = Iw ( ORTHOGONAL ) / Iw ( PARALLEL ) ... (1). In the formula (1), Iw ( ORTHOGONAL ) indicates an infrared absorption intensity of 973 cm<-1> with respect to polarized infrared rays perpendicular to the can height direction at the can barrel portion, and Iw ( PARALLEL ) indicates an infrared absorption intensity of 973 cm<-1> with respect to polarized infrared rays parallel to the can height direction at the can barrel portion. <IMAGE> |
