  • Publication number: 20210031981
    Abstract: An aluminum wine container including an aluminum can body having a barrel portion, and an aluminum can lid that covers an opening of the can body. The aluminum can body has an inner surface on which a polyester resin coating is formed, the coating has a thickness of not less than 4 ?m at the barrel portion, and the aluminum can lid has an inner surface on which a coating film of a polyester/phenolic coating material having a thickness of not less than 6 ?m is formed. Also disclosed is packed wine, prepared by filling the aluminum container with wine and sealing the container.

  • Patent number: 8871351
    Abstract: An easy-open end which is excellent from the standpoint of sanitation and environmental friendliness yet satisfying both the close adhesion and the scratch resistance despite of using a bisphenol A-free primer. The easy-open end has a polyester film applied, via a primer, onto the inner surface of the end of an aluminum base sheet forming a surface-treating layer that contains a zirconium compound and/or a titanium compound and an organic compound, wherein the primer contains a polyester resin that contains not less than 30% by weight of a carboxyl group-introduced polyester resin, and a phenol resin at a weight ratio of 50:50 to 85:15.

  • Patent number: 8470447
    Abstract: An easy open end comprising a resin-coated metal plate obtained by coating a metal substrate with a polyester film via a primer, wherein the primer comprises an epoxy resin or a polyester resin and a resole-type phenol resin, and the resole-type phenol resin has 0.2 to 2.0 methylol groups per a benzene ring. The end can be lightly opened without causing defect at the time of opening the end by pushing in the end of a tab and cutting the score and, particularly, can be excellently opened at high temperatures without arousing the problem even in a state of being heated at high temperatures featuring excellent corrosion resistance, resistance against the content and retort resistance.

  • 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.
