Extrusion Dies Industries LLC (EDI) has announced the availability of a new slot die for coating continuous-web substrates that provides consistent, streak-free application of pressure-sensitive adhesives (PSAs), achieving higher line speeds and greater accuracy than conventional roll coating, with less environmental impact.
EDI developed the die specifically for PSAs. While roll-coating speeds for hot-melt applications usually do not exceed 1200 feet/min. (365 meters/min.), the new die developed by EDI accommodates line speeds up to 2,000 feet/min. (610 meters/min.) and achieves coat weights as low as 0.5 mil (0.0127 mm) - well below the conventional lower limit for hot melts of 1.0 mil (0.025 mm).
In addition to availability as a stand-alone system, the new EDI die can be supplied as part of a completely integrated, computer-controlled coating station incorporating melt delivery systems from ITW Dynatec and slot die equipment from EDI.
