(Poly·ole·fin) is a plastic polymer, the root word olefin refers to any member of the alkene series. An alkene is any unsaturated chemical compound containing at least one carbon double bond. Ethylene is one of the most common olefins. Polyolefins are used in a variety of industries including: automotive, cosmetics, adhesives, packaging and more. Poyolefin shrink film is the most common form of polyolefin used in the packaging industry. Polyolefin shrink wrap offers many advantages over PVC shrink wrap. In recent years, polyolefin has become the preferred shrink material for most shrink packaging applications. Polyolefin- is a polymer that has become a chosen polymer in the packaging industry because of its shrinking properties, clarity, and absence of chloride. Polyolefin is a generic term that refers to a variety of polymers. Polyolefin is considered a thermoplastic material that contracts when heated. It remains odorless when heated and cooled. This is an important advantage over PVC shrink wrap. POF shrink film is the only shrink film we offer that is FDA approved and can come into direct contact with consumable products.
