Resin-coated aluminum seamless can body having excellent body burst resistance and flange crack resistance in distribution

摘要

The invention provides a pot body with high intensity, piercing resistance and flange crack resistance. When the invention is in the transportation process, damage resistant and flange-crack resistant resin is coated on a seamless aluminum pot body; a thermal-plastic resin layer is arranged on the inner or outer surface of the seamless pot body 10; the film thickness of the thermal-plastic resin layer and the thickness of the inner surface and the outer surface add up 2 - 50 um. The thickness of smallest aluminum plate of the pot body side wall is under 0.110 mm. The aluminum plate of the pot body side wall without the thermal-plastic resin has a tearing fracture strength under 450MPa after measured along the circumferential direction of the pot body. The thickness t(mm) of the smallest aluminum plate of the pot body side wall and the tearing strength s (MPa) measured along the height direction of the pot body side wall containing the thermal-plastic resin fulfill the following formula: t X s=30.
