When product passes through the infeed conveyor and reach to sealing area, sensors senses the product and passes the signals to the pneumatically operated sealing bar which retracts the cylinders of sealing jaw causes sealing and cutting of the shrink film. After the seal is made, cylinder again retracts to its original position. Cool air is thrown on the seal to achieve a strong seal. Once the sealing is over, the outfeed conveyor takes the product inside the Shrink Tunnel.
This will transfer the first set of loosely wrapped packs into the tunnel, where the shrinking process will take place and the cycle continues.
