Pallet Wrap or stretch film adheres to itself and can be applied by hand, or by machine. We stock both blown and cast in hand wraps and cast in machine rolls.
Cast or Blown?
Blown stretch wrap, is created by blowing heated resin out vertically into a bubble. The bubble is then transformed into rolls when it has cooled by the surrounding air.
Cast stretch wrap is created by feeding a sheet of heated resin along a series of rollers, continually squeezing the film into wide rolls (same principle as rolling pastry)
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, making it stick to itself.
So, why would anyone use cast film? Cast stretch wrap has a clear, glossy finish allowing scanning technology to be used with it while blown is hazy and dull. Cast stretch film unwinds much quieter than blown. It is also easier to stretch and control the gauge with cast film.
We stock a range of sizes, lengths and strengths in both the cast and blown. Some are available with extended cores making application by hand much easier. Our machine wrap is 23 micron for clear & 25 micron for the black, our hand wraps are from 16 micron to 34 micron.
Mini wrap is very popular and is supplied 40 rolls per box, 100mm x 100 metres x 20 micron. These mini handy rolls of stretch wrap are ideal for bundling lightweight loads which do not need the same ultra-strong packaging as heavier items. Use with a handy wrap dispenser for easy and fast application. Ideal for bundling lengths of timber, plastic and metal.
