Extended Core Stretch Wrapper

	Extended Core Stretch Wrapper Extended core stretch wrappers are rolls of stretch film that have their internal core extended beyond their film roll creating a handle by which film can be wrapped. ''Extended core'' wrapping is the lowest initial investment stretch wrapping system as no machinery is purchased. This system provides little control over stretch and is hard on workers' hands. Because of this, many stretch wrap Stretch wrap or stretch film is a highly stretchable plastic film that is wrapped around items. The elastic recovery keeps the items tightly bound. In contrast, shrink wrap is applied loosely around an item and shrinks tightly with heat. While i ... users opt for low cost hand wrappers such as "hand savers" or '' mechanical brake'' systems.

	Stretch Film Stretch wrap or stretch film is a highly stretchable plastic film that is wrapped around items. The elastic recovery keeps the items tightly bound. In contrast, shrink wrap is applied loosely around an item and shrinks tightly with heat. While it is visually similar to plastic food wrap, it is not usually made of material rated as safe for food contact. It is frequently used to secure pallet loads to one another but also may be used for bundling smaller items. Types of stretch film include bundling stretch film, hand stretch film, extended core stretch film, machine stretch film and static dissipative film. Materials 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 pun ...

While i ...ping systems which consist of a simple structure supporting a roll of film to be stretched and a mechanical brake which acts on the film roll, creating resistance to turning and stretching the film as it is fed out. The amount of braking is often variable by means of either a knob or a lever system. The support structure is most commonly a base paired with a handle, but recently ''pole wrappers'' have been introduced providing a more ergonomic design. References Books * Yam, K.
