<p>PROBLEM TO BE SOLVED: To provide a film having heat insulating properties due to fine air bubbles, not generating wrinkles when laminated, for example, to a metal can and excellent in glossiness, concealability, whiteness, scratch resistance or the like and a laminated metal can. SOLUTION: In a fine air bubble-containing laminated polyester film wherein a polyester B-layer with a density of 1.10 g/cm3 or more is laminated to at least one surface of a fine air bubble-containing polyester A-layer with a density of 0.50-1.00 g/cm3, the heat shrinkage factor of the film in one direction at 110 deg.C is 2.0% or more. A laminated metal can has this laminated film.</p> |
