Abstract: The specification discloses a wrapping film handling mechanism (4) for use with loaded pallet wrapping machinery (10) including a rotatable turntable (11) on which a loaded pallet is placed for wrapping, plastic wrapping film being dispensed onto the loaded pallet with a wrapping direction opposite to a rotation direction of the turntable (11), the film handling mechanism (4) having a pair of gripping jaws (24, 25) pivotally mounted to move between a first inactive and lowered position and a second elevated active position, each said gripping jaw (24, 25) having a gripping portion (84, 85) along one zone that engages wrapping film when the gripping jaws (24, 25) are in the second elevated active position, the handling mechanism including actuation means (114, 115, 31, 90, 91, 93, 94, 96, 97, 120) to move said gripping jaws (24, 25) selectably from said first lowered inactive position to said second elevated active position, said pair of gripping jaws (24, 25) being urged by spring means (42) towards one of sa

Abstract: The invention disclosed herein relates to a method of treating plastics material fibers, filaments or film to improve their resistance to degradation by UV radiation and/or increase their resistance to gas (oxygen) transmissivity and an improved plastics material so treated, the method including stretching the fiber, filament or film beyond its yield point and allowing the film to at least partially relax.
