A popular method of unitizing and palletizing products is stretch wrapping. The film is stretchable and can prevent products from being damaged during the shipping process. Products wrapped in stretch film are more secure. Stretch film is normally used to secure goods on a pallet. Film is rolled around the cargo and stretched. Once stretched, the film returns to its original size. As a result, the load remains tight. It also keeps products dust-free, moisture-free and dirt-free. There are other advantages of using it, which include enhanced packaging efficiency, better control of inventory and improved worker productivity.
