COATING LINES-1

100 % e y trusion COATING LINES ^Hy HIGH-SPEED EXTRUSION COATING LINES ► SML - customised every product Extrusion coated and laminated products are used in a large number of differing market segments and can range from simple PE coated substrates to fast running coated nonwovens for hygiene applications and to complex multilayer barrier structures for flexible packaging. Dedicated line concepts are therefore essential to the fulfilment of specific customer requirements with regard to both products and output. SML designs reach from simple extrusion coating lines to sophisticated tandem coextrusion lamination lines. SML coating lines are fitted with high-output extruders for materials as diverse as polyolefins, EAA, EVA, EVOH and ionomers. Coextrusion involving up to 9 layers and production speeds of up to 600 m/min are both possible, while unwinds can be of shafted or shaft-less design and are able to handle a variety of substrates that includes paper, BOPP, PET and BOPET films, PA, aluminium foil and metallised films. In this context we would like to mention SML’s turret unwinds EcoFlex and PowerFlex.
