Black Pallet Wrap
Black Pallet Wrap also known as Black stretch wrap or stretch film adheres to itself and can be applied by hand, by a pallet wrap dispenser or by machine wrap.
Cast of Blown?
Blown stretch film, or blown stretch wrap as it's also known, is created by blowing heated resin out vertically into a bubble. The bubble is then transformed into rolls while it is cooled by the surrounding air. Cast Stretch film or cast stretch wrap as it's also known, is created by feeding a sheet of heated resin along a rolling path with chilled rollers. The cooling solidifies the film, and it is made into large rolls. We stock both Blown and Cast pallet wrap.
Blown film is tougher and has less of a chance to puncture than cast. This occurs due to the slower cooling process, which allows the molecules in blown film to spread out as opposed to aligning in long lines like in cast. Blown film also has a higher level of cling (think Reynolds Wrap) than cast, making it stick to itself easier.
