Two-piece can, also known as stamped can, is a metal container consisting of a lid and a seamless body. The main materials include aluminum, tinplate, and chromeplate, and it is widely used in the packaging of carbonated beverages and food.
According to different forming processes, two-piece stamped cans can be divided into:
The most important feature of a two-piece stamped can is that the side wall and bottom of the can body form an integral structure without any seams, which confers numerous advantages in durability and leak prevention.
The two-piece stamped can is formed by using appropriate stamping processes to shape a circular blank after several stamping steps. The cup-shaped or other shaped can body after stamping is complete, smooth, and seamless on the side wall. The bottom and side wall are integrated, without the curling and unsealing issues of the side wall and bottom found in traditional three-piece composite cans.
Due to these structural characteristics, two-piece stamped cans are easily processed into various circular or shaped containers. Even for cylindrical two-piece cans, appropriate processing can be carried out on the upper and lower edges to improve structural strength and enhance aesthetic appearance.
