Hot shrinkable wrap, also referred to as shrink film or shrink wrap, is a versatile polymer material used for the packaging of finished goods. Heat is applied to the film – by either a conveyor heat tunnel or an electric or gas heat gun – which catalyzes the film to shrink tightly around the item placed within.
To protect and secure products for retail and shipping environments, there are three main types of films used in shrink wrapping: PVC, polyolefin and polyethylene. Each of these materials features has different capabilities and characteristics that make them suitable for specific applications.
