EDI starts up new lab line for film, coating, and lamination

 The latest addition to an extensive process laboratory at the world headquarters of Extrusion Dies Industries, LLC (EDI) provides new opportunities for customers looking to do product development or trial runs without tying up their own commercial-scale production lines. The expansion at EDI’s Technology Center consists of a 1.6 metre extrusion line that can be used for cast film, coating, or laminat ion and is ful ly equipped for laboratory-scale single- or multilayer production and web converting. The centre also includes a slot die or fluid coating line, a sheet line with six extruders, and other product / process development capabilities. Besides making these facilities available to customers, EDI uses these facilities for its own product and process development research. The new multi-process line can be used for work on product structures ranging from the very simple to the incredibly complex.

 The new line has five extruders and can produce single- or multilayer cast film up to 1,600 mm (63-in.) wide at thicknesses from 8 to 125 microns (0.3 to 5 mils). Speeds for 8-micron LLDPE / LDPE film average 229 m (750 feet) per minute. Multi-layer film can range from standard coextrusions to innovative structures, produced with EDI’s layer multiplier tooling, that can range from a few dozen to over a thousand microlayers. The line also includes two unwind stations for converting film made on the process line itself as well as rollstock purchased from other sources.
