ABSTRACT:
A polyester film-heat-bonded metal sheet is provided, which comprises a biaxially oriented polyester film or films, heat-bonded to a metal sheet by means of an adhesive layer interposed therebetween. The adhesive layer is made of a polyblend comprised of, based on the weight of the polyblend, 5 to 80 wt. % of at least one high melting point polyester having a melting point of at least 200.degree. C. and 20 to 95 wt. % of at least one low melting point polyester having a melting point of at least 100.degree. C., but not higher than a temperature which is 5.degree. C. lower than the melting point of the high melting point polyester. The polyblend may contain a minor amount of a polyolefin resin. The polyester film-heat-bonded metal sheet has good formability and is suitable for cans and other containers. The containers exhibit enhanced impact resistance, adaptability to retort treatment and corrosion resistance.
