What is shrink wrap?
Shrink wrap, also shrink wrap or shrink film, is a material made up of polymer plastic film. When heat is applied, it shrinks tightly over whatever it is covering. Heat can be applied with a hand held heat gun (electric or gas) or the product and film can pass through a heat tunnel on a conveyor.



Why use shrink wrap?
Shrink wrap encloses an item and presents a professional, clean finish. It also provides a durable barrier to dirt, dust, and water and on some products adds a tamper-proof seal.



How is shrink wrap packaging accomplished?
There are three distinct steps to shrink wrap packaging:
  1. Over-wrapping the product in the shrink film.
  2. Sealing the shrink film.
  3. Exposing the Film to heat causing it to shrink and 'fit' the product.
True production shrink wrap packaging is accomplished with an "L" heat sealer and a conveyor shrink tunnel, for lower production a single arm "bar" sealer and a shrink gun can be utilized to produce identical results yet at slower production rates. The quality of both systems is the same.



What type of film is used?
Centerfold shrink film is the most common in use. When shrink wrap is manufactured basically it is stretched like an elastic band, when heat is applied the film returns to its original size. "Centerfold" refers to the fact that the film when made is folded in half so that there are two sheets with a folded edge along the back of the roll. This type of film is readily available throughout the world and the type most shrink machines utilize.
