thickness and elongation are decreased. One of the main features of the MDO unit is the
process-optimised roller arrangement. Adjustment of the stretching gap takes place in a motorised fashion, making product changes simpler. As the stretching rollers have a diameter of 220mm, the stretching gap can be kept in a range of 50-200mm. The distance between stretching rollers can be reduced to a few millimetres. The position of the nip rollers in the stretching area is also adjustable. This ensures an ideal stretching process of the film, independent of the defined stretching gap. All the process parameters of the MDO unit are
digitally recorded and can be comfortably set and adjusted with SML’s new HMI.
Stretching effect At Chinaplas earlier this year, Reifenhäuser also presented MDO technologies for making mono- material films that are more easily recyclable. “In flexible packaging, we are seeing a huge
trend towards recyclable mono-material compos- ites, both for blown and cast films,” said Marcel Perrevort, CSO of Reifenhäuser. “Our MDO stretching units enable enhanced mechanical prop-
erties for all-PE or all-PP films, allowing PET films to be replaced.” With the Evo Ultra Stretch MDO unit for its blown film lines, manufacturers can make all-PE mono films for applications such as high- barrier food pouches. Integrating the MDO unit directly into the haul-off, the film is stretched using the ‘first heat’ of the process, for maximum efficiency and film stability. In addition, the all-PE film achieves the required barrier effect with a 5% EVOH content, which meets the criteria for recyclability. At the same time, Ultra Stretch enhances the performance of the EVOH barrier layer while reducing material usage, delivering cost and sustainability benefits.
