Shrink tunnel light-duty shrink wrapping machines manufactured by vikaash packaging are used for packing various products in singles and multiples using shrinkable ldpe, pvc or polyolefin film in sleeves, pouches or folded form. In these systems the shrinkable film is wrapped over the products and sealed. This pack is sent to the shrink tunnel where the special heating system shrinks the film which holds the product tightly. The pack is then cooled to have a tight shrink wrapping.
