LAMINATED METAL SHEET FOR CONTAINERS, METHOD FOR PRODUCING METAL CAN, AND METHOD FOR EVALUATING FORMABILITY OF METAL SHEET

摘要

PROVIDED ARE A LAMINATED METAL SHEET FOR CONTAINERS THAT HAS EXCELLENT FORMABILITY AFTER HEAT TREATMENT PERFORMED AFTER COATING, PRINTING, ETC. AND IS SUITABLE FOR DR CANS, A METHOD FOR PRODUCING A METAL CAN USING THE ABOVE METAL SHEET AND A METHOD FOR EVALUATING THE FORMABILITY OF A METAL SHEET.THE CRYSTAL STRUCTURE OF A TOP LAYER OF A LAMINATE LAYER OF THE LAMINATED METAL SHEET FOR CONTAINERS AND THE CRYSTAL STRUCTURE INSIDE THE LAMINATE LAYER ARE CONTROLLED IN A SOPHISTICATED MANNER. SPECIFICALLY, THE INTENSITY RATIO I2968/I3085 OF THE RAMAN BAND INTENSITY (I2968) AT A PEAK POSITION AROUND 2,968 CM-1 TO THE RAMAN BAND INTENSITY (I3085) AT A PEAK POSITION AROUND 3,085 CM-1 THAT ARE OBTAINED BY LASER RAMAN SPECTROSCOPY IS USED. THIS INTENSITY RATIO IS CONTROLLED WITHIN A SPECIFIC RANGE.
