<p>PROBLEM TO BE SOLVED: To provide an aluminum can which is easily recyclable, and provide a can lid which is hard to break, and has a favorable unsealing property. SOLUTION: This aluminum can lid comprises a laminated metal plate wherein a thermoplastic resin film 13 is integrally laminated on at least one surface of a metal plate 14. Then, a score 6 is engraved on the metal plate 14. The can lid is unsealed by breaking the score 6. In such a can lid, the metal plate 14 comprises a 3000 series aluminum alloy. In this case, the machining rate of the score on the metal plate 14 is 55 to 65% for the aluminum can lid, and this aluminum can be equipped with the aluminum can lid.</p> |
