Abstract: Provided is a composite Al material for a drawn and ironed can from which a drawn and ironed can having brightness can be formed. In a resin coated metal plate used for forming a drawn and ironed can, a first resin layer (20) having a thickness of 0.02 to 2 ?m is formed on a surface of an Al plate 10 which forms an outer surface of the can, and a second resin layer 30 having a thickness of 1 to 40 ?m is formed on a surface of the Al plate 10 which forms an inner surface of the can. In a penetration test using a TMA device, an insertion amount of a quartz pin when a load of 5 g is applied to the first resin layer at a temperature of 100° C. is 20% or less of a film thickness of the first resin layer. Further, the first resin layer has a room temperature of 10 N/mm2 or more.

Abstract: Disclosed is a resin-coated Al sheet with which a drawn and ironed can having a lustrous appearance can be formed. An upper limit of a thickness of an outer surface resin layer which covers an Al surface which becomes an outer surface of the can and has an arithmetical mean roughness (Ra) of 0.5 ?m or less with a thickness which falls within a range of 0.02 ?m to 6 ?m is determined based on an arithmetical mean roughness (Ra) of the Al surface, wherein the upper limit of the thickness of a coating outer-surface resin layer is decreased when the arithmetical mean roughness (Ra) is increased.

Abstract: A composite resin film enabling a severe forming processing, in which a drum portion or a can is made thinner than a conventional one when the resin film coats a metallic sheet to be formed into a can, maintaining a favorable flavor even when time elapses after contents are filled in the resulting can, and having a high impact resistance which makes the film free from crack even if the resin film is acted on by an impact from outside before and after the filling of contents, and a metallic sheet coated with the resin and having a laminated structure of the composite resin film. The metallic sheet coated with the composite resin film is such that a resin having three layers, an upper layer composed of a resin entirely composed of polyester resin, an intermediate layer composed of a blended resin containing polyester resin and polycarbonate resin, and a lower layer composed of a blended resin containing polyester resin and polycarbonate resin, is laminated on a metallic sheet.

Abstract: A polyester resin film laminated metal sheet having a metal sheet and a polyester resin film on at least one surface. The polyester resin film is 41 to 58 weight percent polybutyelene terephthalate and 42 to 59 weight percent polyethylene terephthalate. This composition provides the polyester resin film laminated metal sheet with an improved resistance to milky discoloration during retort treatment.

Abstract: A triple layered thermoplastic resin laminated metal sheet for a can stock having excellent flavor retention of packed foods and drinks, excellent formability, excellent adhesion of the thus laminated resin layer to a metal sheet and excellent denting resistance, particularly excellent denting resistance at a low temperature, which comprises formation of a triple layered thermoplastic resin layer wherein a polycarbonate resin layer is sandwiched between polyester resin outer and inner layers on one or both sides of a metal sheet covered with a single layer of hydrated chromium oxide or a double layer consisting of an upper layer of hydrated chromium oxide and a lower layer of metallic chromium by using conventional film laminating, extrusion coating or the combination of these techniques.

Abstract: A polyethylene film is heat bonded to a metal sheet provided with a layer of hydrated chromium oxide, and possibly a layer of metallic chromium under the oxide layer. The laminated metal sheet is then rapidly quenched, and the polyethylene laminate is irradiated with an electron beam, gamma rays, or X-rays. Alternatively, the polyethylene film may be irradiated prior to lamination. The laminated metal sheet exhibits excellent resistance to steam and hot water and does not delaminate during forming operations such as can-making.

Abstract: A method for the production of a metal sheet covered with polyester resin film which comprises laminating a polyester resin film which is preferably crystalline and oriented onto a metal sheet having a lower layer of metallic chromium and an upper layer of hydrated chromium oxide, which sheet has been heated to a temperature above the melting point of polyester resin film and then immediately quenching. This metal sheet covered with polyester resin film is excellent in corrosion resistance and formability.

Abstract: Process of producing metal-resin composite, and the composite resulting therefrom, are provided. The process comprises providing a solution or dispersion of a resin, for example, an epoxy resin, said solution or dispersion having dispersed therein at least one particulate metal compound, for example, an oxide, of the Group I A and II A metals of the Periodic Table, the amount of metal compound being 1-500 parts by weight per 100 parts by weight of resin, then coating the solution or dispersion on a metal substrate and heating the coated substrate to evaporate the solvent for the resin and cure the resin. The resultant metal-resin composite is corrosion resistant, especially under acidic conditions, since the resin layer having the Group I A or II A metal compound dispersed therein serves to control the pH on the surface of the metal substrate to within the range of from 4 to 12 under acidic conditions in the atmosphere surrounding the metal-resin composite.
