Detailed Description for Stretch Wrapper

Stretch wrapper is a highly stretchable plastic film that is used for wrapping. The elastic recovery keeps the items tightly in contrast. shrink wrap is  loosely applied around an item and shrinks tightly with heat.

It is used to unitize pallet loads and also used for bundling smaller items. The film around products useful to stabilise, protect and secure the cargo from theft or tampering . There are two main methods in the Pallet wrapping, vertical development and horizontal development. The film is highly stretchable and wrapped around the item that provides secondary protection. It is thus important that the product packaging is stabilized and maintained before and during the wrapping process.


The most commonly used stretch wrap material LDLPE (linear low density polyethylene) , is produced by co-polymerization of alpha-olefins with ethylene,the most common of which are butane, hexane and octane. The use of higher alpha-olefins (hexane or octane) gives rise to enhance stretch film characteristics, particularly in respect of elongation. Other types of polyethylene and PVC can also be used. Many films can be stretched up to 500% ,but are only stretched to about 100 – 300% in use. The two methods of producing stretch wrap are  1) Blown: the resin is melted and extruded through an annular die it is air-cooled and is slower process but provides higher quality.The cost of production is also higher due to the quantity produced per hour is less. 2) Cast: the film is extruded through a die, then passed over cooling rollers. The quality is not as good as blown but more can be produced in an hour with lower costs.

Other properties such as strength, clarity, cling, Static discharge,tear resistance,  etc. are also important.
