ABSTRACT:
A film-laminated metal sheet for container comprises resin films each containing polyester as a main component in two surfaces. A polarity force component γshof an surface free energy of a surface where the resin film to be positioned on an inner surface side of the container after formation of the container is to be in contact with a content is 4×10−3N/m or less.
