The mostly used shrink film is polyolefin. It is available in a variety of clarities, thicknesses , strengths and shrink ratios. 

A shrink film can be made to shrink in one direction like unidirectional or mono-directional, it can also made in both directions like bidirectional.

Films are stretched when users are warm to orient the molecules from their initial random pattern. Cooling the film sets the film's characteristics, this causes it to shrink back toward its initial dimensions.
