Machine Stretch Wrap
The pre-Stretched film is stretched close to its ultimate break point before being wound onto rolls for final use. This means the film doesn’t require as much stretching energy as a standard stretch film to achieve the same wrapping force.
Major Benefits Include
There are many benefits to using pre-stretched film. Basically, users get the same (or better) Load stability with less product, less physical energy, and greater control.
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 stretching is required, so it’s 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 doubles the strength.
Stretch Consistency
The traditional stretch film does not provide uniform stretch, so its performance is unpredictable; this leads to intermittent load failures. The performance of the pre-stretched film is much more controllable.
Price
Pre-stretched film consumption can be less than one-half that of traditional stretch film. This creates a cost savings of anywhere from 25% – 40%.
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 most critical reason for the pre-stretching film.
Other Benefits
No width reduction during tensioning reduces the number of film wraps required and improves productivity.
* Excellent film cling ensures that film tails will stay in place.
* Good film clarity allows easier inspection of packaged products.
* Superior load retention provides better load stability.
* It performs well in extreme cold.
* It facilitates compliance with packaging waste regulations –
using less means less to dispose of.
