Title:
LAMINATE METAL PLATE FOR CONTAINER
Document Type and Number:
WIPO Patent Application WO/2016/159260
Kind Code:
A1
Abstract:
A laminate metal plate 1 is provided with a film 3 comprising at least two laminate resin layers, the main constituent of which is a polyester, formed on one surface or both surfaces of a metal plate 2, wherein a polyester resin layer that is a lower layer 3a of the laminate resin layers and that contacts the metal plate 2 contains 90 mol% or greater of terephthalic acid serving as a polycarboxylic acid constituent, and a polyalcohol constituent is formed from ethylene glycol and 1,4-butanediol, wherein the polyalcohol constituent contains 30-50 mol% of ethylene glycol, 50-70 mol% of 1,4-butanediol and other polyalcohol constituents are at most 10 mol%. A polyester resin layer that is an upper layer 3b of the laminate resin layers is formed from a polyester in which terephthalic acid serving as a polycarboxylic acid constituent and 1,4-butanediol serving as a polyalcohol constituent are both 90 mol% or greater, the total thickness is 3-25 μm, and the ratio (I011/I100) of the peak intensity (I011) observed by X-ray diffraction within the range 2θ=15.5-17.0° to the peak intensity (I100) observed by X-ray diffraction within the range 2θ=22.5-24.0° is within the range 0.2-5.0.
