A type of shrink wrap that has become the preferred choice for packaging products both edible and non-edible. Polyolefin Shrink wrap is preferred for a variety of reasons including: fewer odors when sealed, stronger seal, and more flexible storage. Polyolefin shrink films do not have any chlorine; therefore they do not produce hydrogen chloride gas. Polyolefin shrink wrap does not have any plasticizers, so temperature is not an issue. Polyolefin can be stored in a wide range of temperatures and does not harden and soften in different environments like PVC shrink film.
