POLYESTER FILM FOR METAL LAMINATION AND THE USE THEREOF

摘要

A laminate polyester film to be laminated onto metal plate and molded comprises the first layer made from copoly(ethylene-terephthalate/isophthalate) having a melting point of 205 to 250 DEG C and a second layer made from a polyester (i) comprising ester units of an aromatic dicarboxylic acid component, an aliphatic dicarboxylic acid component and aliphatic diol components, (ii) containing a titanium compound soluble in the polyester in an amount of 30 to 200 ppm in terms of elemental titanium and (iii) having one or two melting point(s) in the range of 170 to 245 DEG C, and has the maximum peak temperature of loss elastic modulus of higher than 47 DEG C and 85 DEG C or lower. This laminate polyester film is suitably used for application such as metal cans for juice and other refreshing drinks that are handled in a cooled state.
