摘要:
A resin-coated metal sheet includes resin layers formed on both surfaces thereof and composed of a polyester as a main component, wherein the resin layer covering the inner surface of a container after the formation thereof has an interfacial free energy with water of 30 mN/m or more. The container formed from the resin-coated metal sheet exhibits an excellent content release property for contents with a high protein content.

摘要:
The mold apparatus has a pair of upper and lower molds being used for forming a score on one side surface of an easy-opening can end fabricated by a laminated metal sheet. The upper mold has a convex part for forming the score, and the cross sectional shape of the convex part at the portion contacting the laminated metal sheet is composed of a curve having a change rate of inclination of 0.08 or smaller to the upper surface of the facing lower mold, or having the curve and a straight line. The formed score has a maximum width of 0.80 mm or smaller.
