PLATE MATERIAL SUCH AS RESIN-COATED ALUMINUM AND MANUFACTURE THEREOF

摘要

PURPOSE: To provide a safe Al material having no separation of a compound film from a resin-coated layer even if a severe treatment such as a retort treatment is conducted even after it is molded with high processability, excellent corrosion resistance and high processing degree and a method for manufacturing the same. CONSTITUTION: A compounded Al material provided on the front surface with a compound film containing 5 to 100mg/m<2> of Cr, 3 to 30 atomic % of Cr, 1 to 10 atomic % of Ti, 4 to 15 atomic % of P, 40 to 70 atomic % of oxygen and 6 atomic % or less of F. Cr atoms are always more than the Ti atoms. A formed Al material composed of 20 atomic % or less of Al and the residue of impurity of hydrogen is covered with a film containing polyester as a main ingredient.
