        There are two main body  seam sealing form: soldering and welding, the former used earlier, but due to the presence of lead solder, has been eliminated the potential; the latter can avoid lead pollution, low energy consumption, less material consumption, but the production of complex equipment. Three piece cans have good rigidity, can produce various shapes of cans, material utilization rate is high, easy to change size, mature production process, packaging products of a wide range of characteristics.
