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.

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.

Abstract: The present invention provides a resin coated seamless aluminum can and a resin coated aluminum can lid having adhesiveness and corrosion resistance by applying a non-chromium chemical conversion coated film to an aluminum alloy sheet and by applying an organic resin layer to the non-chromium chemical conversion coated film. For this end, an organic-inorganic composite surface treated layer containing 2 to 20 mg/m2 of zirconium compound expressed in terms of zirconium atoms, 1 to 10 mg/m2 of phosphorus compound expressed in terms of phosphorus atoms, and 5 to 60 mg/m2 of organic compound expressed in terms of carbon atoms is formed on at least one-side surface of an aluminum alloy sheet, and an organic resin coated layer is formed on the organic-inorganic composite surface treated layer.

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.

Abstract: A laminate for can-making is disclosed, comprising a metal sheet and a thermoplastic resin layer provided on the surface of the metal sheet. The thermoplastic resin layer comprises a laminate film layer comprising a polyester-base resin intermediate layer (A) containing 10 wt % or more of coloring agent particles, a polyester-base resin outer surface layer (B) and a polyester-base resin backing layer (C). The outer surface layer (B) and the backing layer (C) each contains the coloring agent particles in an amount of 20 wt % or less and at the same time, in an amount less than that contained in the intermediate layer (A). Also disclosed is a process for making a can using the laminate.

Abstract: A laminated draw-formed container that is obtained by draw-forming a laminated material of a metal plate on which a resin film is laminated into a cup having bottom, wherein said resin film comprises a surface layer of a high molecular oriented copolymerized polyester derived from acid components of 85 to 97% of terephthalic acid and 3 to 15% of isophthalic acid, and a diol component, and a lower layer of a low molecular oriented copolymerized polyester (B) derived from acid components of 84.5 to 96.5% of terephthalic acid and 3.5 to 15.5% of isophthalic acid, the amount of the isophthalic acid being larger than that of the copolymerized polyester (A) of the surface layer, and a diol component, and said surface layer having a double refraction method orientation degree (.DELTA. n) as represented by the following relation,.DELTA. n=n.sub.1 -n.sub.2wherein n.sub.1 is a refractive index in the direction of a maximum orientation of the film, and n.sub.
