Further, a 200-diameter SOT lid was prepared from the resin-coated metal plate for a can lid according to a standard method.
- Example 13 the Zr film thickness measurement and the surface atomic ratio were measured.
- the can body is heat-treated at 220 ° C for 60 seconds to remove distortion of the resin film according to the usual method, followed by trimming of the open end, curved printing, neck-in to 206 diameter, A 350 g seamless can was made by flanging.
- a 206-diameter SOT lid was prepared from a resin-coated metal plate for a can lid according to a standard method.
- the SOT lid was double-wrapped and sealed.
- a container evaluation was performed in the same manner as in Example 13 except that the aluminum elution amount after opening the can was also measured.
- Condition discoloration can body-can
