COMPOSITE Al MATERIAL FOR DRAWN AND IRONED CAN
Document Type and Number:
WIPO Patent Application WO/2010/146755
Kind Code:
A1
Abstract:
Provided is a composite Al material for a drawn and ironed can from which a drawn and ironed can having a bright appearance can be formed. In a resin coated metal plate used for forming a drawn and ironed can, a first resin layer (20) having a thickness of 0.02 to 2 μm is formed on a surface of an Al plate (10) which defines an outer surface of a can, and a second resin layer (30) having a thickness of 1 to 40 μm is formed on a surface of the Al plate (10) which defines an inner surface of the can. In a penetration test of the first resin layer using a TMA device, the depth that a quartz pin is inserted when a load of 5 g is applied at 100°C is equal to or lower than 20% of the layer thickness. Further, the first resin layer has a hardness of at least 10 N/mm2 at room temperature.
