Aluminum closure sheet is one of the rolled products produced by MC Aluminum. It is used for tamper-proof sealing of pressurized and non-pressurized liquids in containers because of its advantages such as light shielding, good sealing, easy processing and decoration. It is widely used in bottle caps, pull-off caps, Ropp caps, etc.
Rolled aluminum sheet is a process of making aluminum billets into plate-shaped aluminum products through plastic processing methods such as rolling, extrusion, stretching and forging. This process not only includes physical processing of aluminum billets, but also annealing, solution treatment, quenching, natural aging and artificial aging treatment of the finished products to ensure the final performance of the plate.
