Stretch Wrap - Is Pre-Stretch Wrap Better?
Pre-stretched vs non-pre-stretched wrap offer a variety of benefits and drawbacks when compared to one another. One of the biggest differences between the two is the amount of give when using the wrap. Pre-stretched film has already been stretched close to its breaking point before it was wound onto the rolls. As a result, it doesn’t require near as much energy or manual manipulation as traditional stretch film. This allows hand application to be as efficient in terms of load stability as machine applications.
Traditional film needs to be stretched out to about 150% to be fully effective, yet the average person only gets about 115% stretch, resulting in less stable loads and more product loss over time. Pre-stretched film eliminates this part of the packaging process.
Due to the lack of stretch that can be applied by a worker, shipments often are not as stable as they would be with pre-stretched wrap. When using pre-stretched wrap, you achieve greater film memory than you would with tradition hand wraps, thus the stability that pre-stretched wrap provides will help ensure that products get to their destination still wrapped nicely, but more importantly, without as much damage as they would with traditional hand film.
Pre-stretched wrap also allows for more productivity from an employee standpoint. Because of the significant less amount of physical exertion required to stretch the film in traditional hand rolls, fatigue is less of a factor for works, resulting in quicker wrapping and more volume being able to be handled during a single shift. Pre-stretched film can also be used walking forward, allowing workers to navigate the pallet quicker. The pre-stretched rolls are also lighter than traditional films, making it a more accessible task to all works. Pre-stretch film has another cost-saving benefit associated with employee health. With all these properties, pre-stretch film reduces unnecessary torque on the body and vastly reduces the slip and fall incidents that have been known to go along with stretch film application.
As far as cost benefits are concerned, pre-stretched film can produce a decrease in overall shipping cost because of the lesser amount of wrap used compared to traditional stretch film. Usually, only about half as much pre-stretch film is needed compared to traditional, setting up a cost savings of about 25-40%. Pre-stretched film also provides a consistent, uniform covering, eliminating the guesswork associated with inconsistent traditional wrap. This film also has reinforced edges due to the stretching process, eliminating film lost like you have with traditional film if the film is dropped.
Pre-stretch wrap provides some environmental advantages as well. The film has great clarity, allowing for inspection without any waste or re-wrapping to occur. In addition, since you are using less than traditional wrap to begin with, there is less waste to dispose of after delivery.
To summarize, if you are looking for a product that is more efficient than traditional stretch film, will increase user productivity while eliminated needless risk, and be more cost efficient on both the product and HR fronts, then it might be time to switch from traditional stretch wrap to pre-stretched wrap.
