METAL PLATE COATED WITH POLYESTER RESIN, AND CAN USING THE SAME

摘要

A metal plate coated with polyester which comprises a metal plate and, coating at least one surface thereof, a single polyester resin layer having an intrinsic viscosity of 0.6 to 1.4 and a half-crystallization time of 50 seconds or more, or two polyester resin layers wherein an upper polyester resin layer has a half-crystallization time less than 80 seconds and a lower polyester resin layer has that of 50 seconds or more, and both layers have an intrinsic viscosity of of 0.6 to 1.4; and a can using the metal plate. The metal plate coated with a polyester is free from cracking or breaking even when it is subjected to severe forming or processing such as wall-thinning and deep drawing and is excellent in processability and corrosion resistance, and the can is excellent in preservation of flavoring properties of the contents thereof.
