advantages of two-piece can

Compared with the three-piece can, the two-piece can has the following advantages:

①Good airtightness. The can body is directly formed by the punching process, no leakage, and the leak detection process can be avoided.

②Ensure product quality. The two-piece cans do not need to be welded and sealed to avoid lead contamination of the solder cans, and are resistant to high temperature sterilization, which can ensure product hygiene.

③Beautiful and generous. The can body has no seams and beautiful appearance, and the can body can be continuously decorated and printed with good effect.

④ High production efficiency. The two-piece can has only two parts, and the can body manufacturing process is simple, which is of great benefit to simplifying the process and improving the production capacity.

⑤Save raw materials. The body of the two-piece can is stretched and deformed when it is formed, and the wall thickness is thinner than that of the three-piece can; in addition, the body of the two-piece can is integrally formed without the longitudinal seam of the can body and the seam with the can bottom, which also saves material .

However, two-piece cans have higher requirements for material performance, canning technology, canning equipment, etc., and there are fewer types of filling materials.
