The present invention relates to a portable electric wrapping apparatus, comprising a motor to drive a main shaft, which moves a tensioning mechanism and a sealing and cutting unit. The tensioning mechanism and the sealing and cutting unit can be designed as individual modules and put together with the main body. The tensioning mechanism may be two frictional wheels each having cutting grooves or a single wheel aiming at the frictional plates to evenly apply pressure to the packaging tape therebetween and strain it for wrapping a package tightly. With the aid of a tension control rod, the tensioning mechanism can move the sealing and cutting unit downward to weld and cut the packaging tape automatically. |
