Tensioning foil must not be missing in the team

Fixing boxes and small parts on a pallet can be compared to coaching a football team. The tighter the individual members stick together, the greater the cohesion and subsequent performance of the entire team. Your role as the “head coach” in pallet wrapping is to secure the individual items in the optimal position on the pallet unit (see the article “Optimal palletisation” on our blog), thereby ensuring the stability of the entire pallet.

The simplest and most effective solution to this task is tensioning films. They protect the products from dust, dirt and moisture, and are also very versatile: from homogeneous pallets to sharp-edged loads of irregular shapes.

The tensioning process

The films, which are supplied in rolls, are stretched during unwinding. This makes the stretched films very elastic. Tension occurs when the PE material contracts to regain its starting position. A similar process can be observed, for example, when stretching ordinary rubber bands. In this process, the recoil force provides the desired longitudinal shrinkage of the film. The width of the film therefore remains constant during tensioning. You will therefore secure a larger area of the pallet load than with standard manual tensioning films and reduce the number of wraps.

Maximum performance thanks to tensioning

As already mentioned in the above text, the more the film is tensioned, the higher the back force and the more stable the pallet fixation. Pre-tensioned tensioning films are an effective aid for optimal wrapping. Some types of these films are tensionable up to 250%. Pre-tensioned films are tensioned by machine to the maximum possible limit (thus reaching a much higher tension than with conventional manual tensioning), and as a result you fix the pallet with less material consumption(approx. 50%). When applying the pre-tensioned film you also reduce the subsequent residual waste by up to half.

And the best part? You achieve this great result with minimal effort and time. As you can see, time and physical strength savings can be found not only in sports, but also in packaging materials!
