The biggest advantage of Polpack is that it is easy to inject air. When using a third-party product, it was often necessary to pump the packaging material by hand more than 10 times. This took considerable effort and time.
However, in Polpack, air is automatically injected by simply stepping on the foot-switch. One person with Polpack is enough for the packaging work that 3-4 people would do. Operational efficiency is greatly increased.
