Can body having improved impact

摘要

A metal can body of improved impact resistance of the body wall is formed by drawing and/or pressing subsequent to preliminary coating of an organic resin on at least one side of the metal surface that becomes the inner surface of the can body. The main component of the organic resin coating is a polyester resin containing oriented crystals. The intrinsic viscosity (IV) of the polyester layer is 0.60 or higher. Parameter A representing the ratio of axial orientation in the direction of the can height is A>/=0.40. and Parameter B representing the degree of plane orientation of axially oriented crystals in the direction of the can height is B>/=0.00.
