The top and bottom grip portions define a film roll engagement mouth which is openable and closable by moving the bottom handle portion against the top handle portion. At least one of the top and bottom grip portions include lateral guide faces for laterally retaining the spool in the film roll engagement mouth. A biasing spring may be positioned between the top and bottom handle portions for urging the top and bottom grip portions toward each other to firmly retain a roll of film within the film roll engagement mouth. A tensioning lever or knob may be provided which may be engaged with the spool when the roll of film and spool are engaged in the film engagement mouth, for rotating the spool and tightening the film thereon. A device for taping the end of the roll of film may be mounted on the top tong arm for dispensing tape in the vicinity of the film engagement mouth which can be utilized to seal the roll of film closed.
