The combo serie are machines for the packing on 6 sides, with two winding stages. The first stage wraps the bundle pushing it against a stretched polyethylene film and then welding the film at the end of the bundle. The second one wrap the bundle in the other direction by a rotating unit holding the film roll.
These machines allow to wrap small and big size bundles, both on 4 or 6 sides, ensuring perfect stability of the wrapped product for every size. Furthermore, the missing of the shrinking tunnel drastically reduces the energy consumption compared with bag systems.
