That’s why it’s important to select the right wrap for the job. Many conventional films are made up of 5-7 layers squeezed together, giving it more strength and elasticity. More elasticity not only translates into a tighter fit around the load, it also provides a greater yield from a roll of film.
Stretch to secure
Clearwrap is a popular upgrade from standard plastic film because it guarantees up to 200% yield per roll. That can only be achieved when using a stretch wrap machine of course. When wrapping by hand plastic film can only be pre-stretched by around 20-60%.
But for those hand wrappers there are options for wrap that’s easy to apply tightly with minimum effort. A film like Quickwrap offers superior puncture resistance and also comes pre-stretched. The extra air in the roll created by the pre-stretching process makes it lighter and easier to apply and because it’s already pre-stretched, securing the load requires less wrap.
Looking at the latest film technologies is where things get really exciting. Thinner, stronger and more elastic, NanoWrap is the most recent addition to our range. This film provides unprecedented level of stretch thanks to specialist resins and production machinery that combines 33 layers to create an ultra-thin, super-tough film – one that can reduce wrap use by 35-50%.
So to answer the original question, how much should you stretch, it all depends. But whether hand-wrapping or letting a machine do the work, knowing your load containment metrics is a good place to start. Get in touch for our help with this.
