Our cast pallet stretch film is good quality heavy duty pallet wrap. If you want cheap you will get nasty and that does not work in a commercial environment. With all pallet wrap you have to stretch the pallet wrap, in stretching it will want to return to its original length.
So the more stretch you apply the more it will try and contract around the product on the pallet. Therefore you have to be careful, if the product is fragile do not stretch to much because as is tries to contract to its original length it will crush your product.
