How much does stretch wrap stretch? Is more better?

March 27, 2020

Sometimes you'll hear people refer to the plastic that they wrap around pallets as shrink film. You know what they mean of course, but the proper name is stretch film for a reason.

Modern stretch film formulations are made to stretch - but maybe not for the reason, or to the extent that you imagine.

When Pat Lancaster invented the first stretch wrapper in 1972 he used a 60” roll of plastic film designed for use in dry cleaning facilities. The idea was to lay the film against the rotating pallet and rely on a core brake to slow the film enough that it stretch a bit and compressed the load as a result. That invention rapidly evolved to the spiral wrap so popular today. The polyethylene stretch film we rely on now rapidly followed.

That's essentially the same process repeated thousands of times each day as workers hand wrap loads with 12 & 18" wide rolls of hand stretch film.

And most importantly, load security is determined by containment force - or wrap force X film layers. It turns out that stretching isn't a factor.
