A method of stretch wrapping goods with stretch wrap film, the method comprising the steps of:
- dispensing at least one band of film from a single stretch film core;
- roping the at least one band of film by edging at least one lateral side edge of the film;
- pre-stretching the film by passing the roped film through a pre-stretcher;
- wrapping the roped pre-stretched film around the goods, wherein the method is characterized in that the step of roping is performed prior to the step of pre-stretching and the single core comprises a plurality of bands of film accommodated on the single core, which plurality of bands of film are formed on the single core by precutting a unitary width of stretch wrap film disposed on the single core.
Apparatus for applying stretch wrap film to unitize a pallet load of goods, the apparatus comprising:
- a film roll carriage adapted to accommodate at least one stretch wrap film roll and dispense a plurality of individual bands of stretch wrap film from a single film roll;
- a roping mechanism comprising roping fingers to rope the dispensed individual bands of film;
- and a pre-stretcher for pre-stretching the dispensed individual bands of film, characterized in that:
- the film roll carriage is operatively connected to a slitter rewinder adapted for receiving stretch wrap film from the film roll carriage, slitting the stretch wrap film into the plurality of individual bands of stretch wrap film and rewinding the plurality of individual bands of stretch wrap film onto the film roll carriage;
- and,
- wherein the plurality of individual bands of stretch wrap film are passed through the roping mechanism prior to the pre-stretcher.
