One Chinese company wanted to pack tea leaf into flat nylon bags and also envelope bag, it is different for us, because we have only pyramid nylon bags. In order to meet this packaging demand, we specially designed new DXD01YS80 machine for this customer. The machine DXD01YS80 successfully integrated the pyramid machine and the envelope bag machine. Through integration control, the packaging of flat bags and envelope bags can be realized on DXD01YS80 with high speed and good stability.
