High Quality Hand Stretch Film Shrink Wrap Clear Plastic

Stretch film is the most common stretch packaging material of linear low density polyethylene or LLDPE, which is produced by the copolymerization of ethylene with alpha-olefins, most commonly butene, hexene and octene. The use of higher alpha-olefins (hexene or octene) can enhance the performance of stretched 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 be stretched to 100-300% in use. After stretching, elastic recovery is used to keep the load firm.
