摘要:
The resin-coated metal sheet is composed of: a metal sheet; a lower resin layer containing a hydrophilic copolyester, formed on at least one side of the metal sheet; and an upper resin layer containing a polyester containing a diol component composed of a diol derivative of 1 to 10% by mole of alicyclic compound and 99 to 90% by mole of ethylene glycol, and a dicarboxylic acid component consisting of terephthalic acid, formed on the lower resin layer. The sum of cyclic trimer of alkylene terephthalate existing in the upper resin layer and the lower resin layer is 0.9% or less by mass. Since the manufacture of food cans using the resin-coated metal sheet does not induce white haze phenomenon and retort blushing phenomenon on outer surface of the can even after retorting, the decorative appearance on outer surface of the can is not deteriorated.

摘要:
The resin-coated metal sheet has: a metal sheet; a lower polyester resin layer having 0.03 or smaller plane orientation factor and 5 to 20 μm of thickness, being formed on at least one side of the metal sheet; and an upper polyester resin layer containing 0.1 to 5% by mass of olefin wax, having larger than 0.06 and not larger than 0.15 of plane orientation factor and 0.5 to 10 μm of thickness, being formed on the lower polyester resin layer. The metal sheet assures excellent taking-out performance of the contents also those of low fat and high protein foods, and provides formability and adhesion requested for the container working.
摘要:
A resin-coated metal sheet includes resin layers formed on both surfaces thereof and composed of a polyester as a main component, wherein the resin layer covering the inner surface of a container after the formation thereof has an interfacial free energy with water of 30 mN/m or more. The container formed from the resin-coated metal sheet exhibits an excellent content release property for contents with a high protein content.

摘要:
A colored laminated metal plate for containers includes a metal plate having one or both surfaces coated with a film for lamination in which a colored adhesive layer is coated to a polyester resin film. The colored adhesive layer contains a polyester resin as a main component and further contains an etherified amino resin, an epoxy resin, a strong acid compound, and a coloring agent. The colored laminated steel sheet is excellent in deep drawability, adhesion after forming, rust resistance of a damaged portion, and so on. When the steel sheet is applied to manufacturing of a container such as a can, retort whitening of the laminate film hardly occurs, and the design properties of appearance can be maintained.

摘要:
The present invention relates to a resin film laminated metal sheet for can, in which both faces of the metal sheet have resin film laminated layers, and a surface free energy γ s of a face of the resin film is 10 dyn/cm or more to less than 30 dyn/cm, the face becoming an inside of can after can-making and being contacted with stuffed food contents. As the resin film, applicable is a polypropylene film or a propylene ethylene based random copolymer film of polypropylene being a main component. Further, a resin film of polyester being a main component and containing a wax component of 0.1 to 2.0% is used in a resin film to be an inside of can after can-making. The resin film laminated metal sheet for can according to the invention has excellent formability and adhesion while can-making and superior taking-out property of stuffed food contents.
