Abstract: A metal sheet for containers includes a metal sheet and a polyester film which is laminated on a surface of the metal sheet to be an inner surface side of containers. The polyester film contains a wax in an amount of 0.010 to 2.000 mass %, and has a dipole-dipole force of 40 mN/m or less.

Abstract: A film-laminated metal plate having excellent retort adhesiveness includes: a metal plate; a resin film thermally fusion-bonded to a surface of the metal plate; and a bubble contained between the metal plate and the resin film. An average bubble height of three bubbles with higher heights among the bubbles measured by using a 3D analysis image of a laser microscope is 0 ?m or more and 5.0 ?m or less. The test piece is obtained by cutting a portion of one end side of the metal plate in a longitudinal direction while leaving the resin film on a side which becomes an inner surface side of the container when the film-laminated metal plate is processed into a container. When a retort treatment is carried out on the test piece at a temperature of 125° C.

Abstract: When laminating two types of film (1, 2) with different melting points on the two sides of a metal sheet (3), the thickness of the low melting point side film (2) is adjusted. Specifically, the thickness d2 of the low melting point side film (2) at the part sandwiched between the lamination roll (10) and metal sheet (3) is made a range defined by d2?k(?MP??T)/V. Here, ?MP is the difference of melting points of the two types of film, k is k?2, 0<?T=MP1??Ti?50(° C.) (Ti is the metal sheet temperature at the inlet side of the rolls, V is the sheet running speed, ? is a constant determined by the heat removal conditions at the time of lamination, where 0.75??<1). Due to this, sticking of the low melting point side film (2) to the lamination roll (10) can be prevented.
