Stretch film is the most common stretch packaging material of linear low-density polyethylene or LLDPE, which is produced by copolymerizing ethylene with α-olefins, the most common being butene, hexene and octene. The use of high-grade α-olefins (hexene or octene) can enhance the properties of stretch films, especially in terms of elongation at break and puncture resistance. Other types of polyethylene and PVC can also be used. Many films have an elongation at break of about 500%, but can only stretch to 100-300% in use. After stretching, elastic recovery is used to keep the load compact.
