Title: FILM LAMINATE METAL PLATE HAVING EXCEPTIONAL RETORT ADHESION, AND METHOD FOR MANUFACTURING SAME
Abstract:
This film laminate metal plate having exceptional retort adhesion is provided with a metal plate, a resin film thermally fused to the surface of the metal plate, and air bubbles included between the metal plate and the resin film. When a 3D analysis image from a laser microscope is used to measure the height of the air bubbles, the average of the three highest air bubble heights is 0-5.0 μm. In a state where a test piece is used that has part of one longitudinal-direction end of the metal plate cut away so as to leave the resin film that is on the side forming the inner-surface side of a container when the film laminate metal plate is machined into at least the container, a 100 g weight is suspended on the one end of the test piece, and the other longitudinal-direction end of the test piece is turned back 180°, when the test piece is subjected to a retort process for 30 minutes at a temperature of 125°C, the length of the resin film that peels away from the metal plate is 15 mm or less.
