Abstract: A method and system for perforating stretch film. The stretch film may be extruded using a cast film or blown film extrusion process. The stretch film may be passed over a first idler roller and moved in a first direction toward a perforation roller. The perforation roller may have a center axle and a plurality of perforation rings, each of which has an outer ring, a plurality of pins extending through the outer ring, and an inner ring configured to hold the plurality of pins in an extended position through the outer ring. The stretch film may be perforated with the perforation roller as the stretch film passes over the perforation roller. The perforated stretch film may be moved in a second direction away from the perforation roller, passed over a second idler roller, and wrapped about a core to form a roll of perforated stretch film.

Abstract: A method for wrapping a palletized load. A first spool with first, second, and third rolls of stretch film and a second spool with a roll of perforated stretch film may be provided. A top edge and bottom edge of the stretch film from the first, second, and third rolls of stretch film may be banded. The first, second, and third banded stretch films may be layered onto the perforated stretch film to form a layered stretch film. The first banded stretch film may extend along a top edge, the second banded stretch film may extend along a center, and the third banded stretch film may extend along a bottom edge of the perforated stretch film. The perforations in the layered stretch film may be expanded into a plurality of voids. The layered stretch film may then be wrapped around the palletized load.

Abstract: Perforated stretch film tube for forming a perforated stretch film hood. A length of flattened stretch film with a thickness of between 0.0025 and 0.0055 or larger is perforated after extrution and wound around a core to form a roll of perforated stretch film tube with a plurality of perforations spaced spaced by at least an inch and having a diameter of less than ½ inch. The roll is loaded into a palletized load hooder machine, opened with gripping arms, sealed and cut at one end to form a pallet hood, and drawn down over the palletized load and released to secure the load to the pallet.

The pre-stretch carriage is configured to pre-stretch stretch film and has at least two stretch rollers and a hinged door. The at least two stretch rollers includes a first stretch roller with an outer surface that moves at a first speed and a second stretch roller with an outer surface that moves at a second speed higher than the first speed.

The encoders are mounted on the door. Each of the encoders is configured to contact the stretch film on the outer surface of one of the stretch rollers and measure a length of stretch film passing over that stretch roller.
