The Main Benefits Of Stretch Films

Stretch films is expanded close to its ultimate break point prior to being wound onto rolls for final use. This means the film doesn't require as much user energy as a standard film to achieve the same wrapping force. This is a key reason why pre-stretched films are popular for hand wrap. In fact, with pre-stretched wrap, hand applications can create the same load stability as machine applications. The benefits of this are obvious.

In terms of material costs, Stretch films are much thinner than traditional films. Ultimately, this produces less environmental waste since the operator uses less material during application.Manufacturers create pre-stretched film by elongating it mechanically between 2 film carriage rollers. Since the surface of the secondary (larger) roller rotates faster than the primary roller, the film gets pulled between them and expands. The resulting rolls are generally light and easy to handle, reducing operator fatigue. Since there's very little torque involved, users also benefit by being able to use a walk-forward wrapping technique, which can help prevent slip and fall incidents.

Major Benefits of Stretch films Include:Basically, users get the same (or better) load stability with less product, less physical energy, and greater control.Consumption can be less to one half that of traditional film. This creates a cost savings of anywhere from 25% - 40%.No Edge Damage (no wasted rolls)It has rolled edges and has air blown into the roll to support the middle of the roll from telescoping down. These two processes together make it almost impossible to damage the roll edge when dropping it. Traditional film rolls often are thrown away because the user drops them and damages the edge.

Easier to Apply ,Lower torque requirements allow users to walk forward instead of backward during application - making for safer and easier control. Also, little or no expansion is required, so it much easier to wrap with less physical strength. The roll is lighter (about 2/3 less than traditional film) and easier to manage. It's about half the thickness and double the strength.Film Memory ,Since the film is applied to the load with little force, it will naturally tighten after application. This unique film memory and its tendency to tighten after application is the single most important reason for Stretch films.Consistency ,Traditional film does not provide uniform expansion, so its performance is unpredictable; this leads to intermittent load failures. The performance of pre-stretched film is much more controllable.
