Stretch wrap

It is frequently used to secure pallet loads to one another but also may be used for bundling smaller items.

The most common stretch wrap material is linear low-density polyethylene (LLDPE), which is produced by copolymerization of ethylene with alpha-olefins, the most common of which are butene, hexene and octene.

The use of higher alpha-olefins (hexene or octene) gives rise to enhanced stretch film characteristics, particularly in respect of elongation at break and puncture resistance.

There are two methods of producing stretch wrap: Other properties such as break strength, cling, clarity, tear resistance, static discharge, etc.

In pallet unitizing, stretch wrap can have several functions: Making sure boxes stay on the pallet and properly aligned is an important consideration in warehouse distribution, especially as the demands for increased throughput continues to rise.
