Structural features of packaging cans:

There are several unique sealing points between the packaging can body and the packaging lid to ensure no leakage of liquid.

The inner edge of the cover ias equipped with a ring of reinforcement to ensure that the accumulated load is transferred to the reinforcement.

The use ratio of raw materials increased by 7% compared with the traditional process. Reduces multi-process, saves cost and improves production efficiency by stamping the whole roll of laminated steel.

It can extend the service life of the bottom and lid, and the surface of the bottom and lids not easy to be damaged, reduce return rate and improve product satisfaction.
