<p><P>PROBLEM TO BE SOLVED: To provide a polyester-based film for laminating a metallic sheet which is good on aroma preservation and corrosion resistance, can be laminated on a metallic sheet at a lower temperature than that for a conventional film, independent of the kind of the metallic sheet and is fit for a container for various kinds of drink or food, and, when the film is cut at a state of a film-laminated metallic sheet, snar yarn does not generate and on a winding-fastening process of a can at relatively deeply drawing such as a deformed can or the like, any shavings of the film are not formed, and to provide a film-laminated metallic sheet and a metallic container produced by forming the metallic sheet. <P>SOLUTION: The polyester film comprises A layer of polyethylene terephthalate and B layer of a polyester composition comprising mainly butylene terephthalate, a ratio of thickness of the layers shown as the A layer: the B layer is (75 to 95):(25 to 5)%, the temperature for laminating the B layer with the metallic sheet is below 200°C, an intrinsic viscosity of the resin forming the A and B layers respectively is set in a range of 0.5-0.7, and the B layer side of the film is coated by a film comprising a water soluble polyester-polyurethane resin composition. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
