Stretch wrap 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.It is frequently used to unitize pallet loads 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. stretch wrap can have several functions: • improved stability of products or packages • more efficient handling and storage of unit loads • some degree of dust and moisture protection • some degree of tamper resistance and resistance to package pilferage

Poly shrink film

Poly shrink film, is a material made up of polymer plastic film. When heat is applied, it shrinks tightly over whatever it is covering.  Heat can be applied with a hand held heat gun (electric or gas) or the product and film can pass through a heat tunnel on a conveyor.

A shrink film can be made to shrink in one direction (unidirectional or mono-directional) or in both directions (bidirectional). Films are stretched when they are warm to orient the molecules from their initial random pattern. Cooling the film sets the film's characteristics until it is reheated. This causes it to shrink back toward its initial dimensions.

Shrink wrap can be used to wrap buildings. It can wrap roofs after hurricanes, earthquakes, tornadoes and other disasters. Shrink wrap can be used for environmental containments to facilitate safe removal of asbestos, lead and other hazards.

Advantages of poly shrink film are Economical Packing, Tamper evident, Prolonging Shelf Life, Neat and Presentable with Sales Appeal, Total Protection –Water Proof, Protection against Rain, Dust, Moisture, Humidity etc., it should be Usage of Shrink Machine/Shrink gun Poly.
