  • Patent number: 8221872
    Abstract: An easy-open end comprising a resin-coated metal plate obtained by coating a metal substrate with a anti-blocking agent-containing biaxially drawn film via a primer, wherein an important feature resides in that the anti-blocking agent in the biaxially drawn film is of a spherical shape having an average particle size of 0.5 to 2.5 ?m and an average particle size ratio (long diameter/short diameter) in a range of 1.0 to 1.2, and is contained at a ratio of 0.05 to 0.5% by weight in the biaxially drawn film. Even without forming a top-coat layer, therefore, the film is not scratched or the forming-tool is not damaged by the anti-blocking agent that adheres and deposits on the forming tool. Besides, the resin coating favorably adheres to the metal plate offering excellent advantage in production and in economy.
