Stretch cover system

Another method for pallet stabilisation is the use of stretch covers. The use of stretch tubular wrap in combination with the application of a floor sheet - for stacking - also provides a waterproof result. A stretch cover provides tension, in both a horizontal and a vertical direction, and this tension is significantly higher than with shrink covers or cling wrap. Goods are thus very well stabilised. The stretch cover shapes itself according to the form of the pallet load.No oven is necessary, thus energy expenses are lower. Stretch covers do not cling to the load and can be processed quickly and the presentation value is high. This process is safer with regard to fire hazard, saves on energy and it is cheaper than the shrinking process. It is however not true that stretch covers are suitable for every application. When the load is extremely light or easily deformable, a stretch cover can not be used.

The application process is substantially different from that of shrink covers. Where in the application of shrink covers, the cover is placed loose around the pallet load, to then be shrunk, with a stretch cover the cover is prepared to be stretched over, to then be pulled around the pallet load under tension. The stretch cover returns to its original form and seals perfectly around the load.

Once the machine is given all necessary parameters (this can often be determined by sensors) the machine determines the height of the stretch tube and this is rolled off. The machine makes a seam in the top and cuts off the material. The stretch tube is unwound using 4 drawing arms. The neat unrolling of the foil also provides a neat final result. After stretching, the foil is pulled over the load. The wrap returns to its original size and shapes itself like a smooth skin around the load (see photo collection).
