Shrink wrap, also shrink film, is a material made of polymer plastic film and used all around the world to ship full and partial pallet loads and keeps them intact from point A to point B. Heat can be applied with a handheld heat gun(electric or gas), or the product of film can pass through a heat tunnel or conveyor.

How is shrink film(shrink wrap) manufactured or made of?

Films are stretched when they are warm to orientate molecules to form there initial random pattern. Cooling the film sets the film’s characteristics until it is reheated: this causes it to shrink back towards its initial dimensions.

Polyolefin is the most commonly used shrink wrap.
