LAMINATED STEEL SHEET FOR CAN

摘要

PURPOSE:To obtain a precoated steel sheet for a can wherein it is easy to weld and adhesion of a resin film is not deteriorated by retort treatment. CONSTITUTION:The steel sheet is obtained by laminating biaxially oriented polyethylene terephthalate resin to metallic chromium layer or a limited chromium plated layer of a chromium hydrated oxide layer or a plated steel sheet which possesse an Sn plated layer and a chromate layer on a chromium plated layer and has appropriate surface roughness by making use of an adhesive agent having limited favorable short time curing properties in a beltlike state by leaving a varnish guard part behind and hot-press-bonding polyethylene terephthalate resin containing appropriate quantity of isophthalic acid similarly to the laminated steel sheet and plated steel sheet. Thereby, since thermal shrinkage of a resin film is not generated even though weldability is secured, adhesion of the film is favorable and a problem of neither elution nor whitening is generated by retort treatment.
