TechnoWrapp A800 and A800 4E pallet stretch wrapping machines

TechnoWrapp has upgraded its A800 and A800 4E automatic ring wrapping machines with an integrated top sheet applicator. The high-speed machines are for wrapping palletised loads with stretch film and a waterproof top sheet.

These highly productive wrapping machines are designed to keep film usage to a minimum, with up to 350% material savings claimed, and yet ensure complete hermetic sealing of the pallet stack. The ring technology rotates the film cartridge around the palletised load, combining smooth horizontal and vertical movements to cover the load, while still maintaining the integrity of the load corners.

The top sheet applicator places a sheet of polyethylene on the top of the load which, together with the lateral wraps, creates a waterproof covering of the product.

The electronic prestretch system with a tacho generator enables smooth dispensing of the film and a high degree of prestretch. The wrapping machines use as little as 96 g of film, which is achieved by prestretching the film to more than 400%. On a pallet measuring 800 x 1200 x 1500 mm high, using nine layers of film and a standard film reel of 500 mm wide x 23 µm, only 96 g of film is used.

The automatic pallet stretch wrapping machines can wrap up to 130 pallets/h and hermetically seal the top and sides of the load. Optional extras include an auto reel changeover, stretch film splicer and pallet lift in wrapping area.
