Resin coated metal sheet for using drawn and ironed cans, drawn and ironed can, and method of manufacturing drawn and ironed can

Abstract

There is provided a resin coated metal sheet for using drawn and ironed cans. The resin coated metal sheet is to be made into a can body by drawing and ironing. The resin coated metal sheet includes a metal sheet and a resin layer. The resin layer is formed on a surface of the metal sheet to be a can outer surface. The resin coated metal sheet for using drawn and ironed cans is characterized in that the resin layer having a storage elastic modulus of 500 MPa or less within a temperature range of 90-150° C. and a degree of breaking elongation of 100% or more within the temperature range of 90-150° C.

What is claimed is: 
     
         1 . A resin coated metal sheet for using drawn and ironed cans which is to be made into a can body by drawing and ironing, comprising:
 a metal sheet and   a resin layer which is formed on a surface of the metal sheet to be a can outer surface, wherein   the resin layer has a storage elastic modulus of 500 MPa or less within a temperature range of 90-150° C. and a degree of breaking elongation of 100% or more within the temperature range of 90-150° C.   
     
     
         2 . The resin coated metal sheet according to  claim 1 , wherein the resin layer has a thickness of 0.02-2 μm. 
     
     
         3 . The resin coated metal sheet according to  claim 1 , wherein the metal sheet comprises an aluminum sheet. 
     
     
         4 . A drawn and ironed can obtained through a drawing process and an ironing process for the resin coated metal sheet according to  claim 1 . 
     
     
         5 . A method of manufacturing a drawn and ironed can comprising:
 forming a resin layer on a surface of a metal sheet to be a can outer surface, the resin layer having a storage elastic modulus of 500 MPa or less within a temperature range of 90-150° C. and a degree of breaking elongation of 100% or more within the temperature range of 90-150° C.; and   processing the metal sheet formed thereon with the resin layer into a can body by performing a drawing process and an ironing process so that a body part of the can body after the processes has a specular reflectance of 15% or more.   
     
     
         6 . The method of manufacturing a drawn and ironed can according to  claim 5 , wherein the resin layer has a thickness of 0.02-2 μm. 
     
     
         7 . The method of manufacturing a drawn and ironed can according to  claim 5 , wherein the metal sheet comprises an aluminum sheet.
