wave resistance at the time Distribution and flange cracking resistance is excellent resin-coated aluminum and the seamless can body

摘要

naedol magnetic penetration strength is high at the same time, a challenge that is excellent and provides a good can body flange crack resistance The. ; wave resistance and crack resistance is excellent resin-coated aluminum flange at the distribution of the present invention and the seamless aluminum can body is seamless and can body (10) inner surface and / or thermoplastic resin layer on the outer surface of the can is formed, the thickness of the inner thermoplastic resin layer and an outer surface 2 ~ 50 The total thickness of the can body side wall of at least the aluminum plate is below 0.110 , removal of the can body side wall of the thermoplastic resin to the aluminum plate in the circumferential direction of the can The measured tension ( ) a breaking strength of more than 450MPa, the thermoplastic can body side wall portion at least part board comprises a resin layer thickness t ( ) and, as measured thermoplastic resin layer with the can height direction portion can having a side wall including a tensile strength s (MPa) with the product of the t s 30.
