Knife cut edges provide a very soft edge which is also non-abrasive. The cutting process, generally conducted with a steel blade, generates the most extraneous fibers or loose ends for cleanroom wipe cuts. This is the most economical option for less critical cleanroom application but also the most prone to linting or particle shed.

Laser sealed edges provide extremely precise edges with minimal disruption of surrounding material. The process ensures zero loose particles or split end for ultra-clean, heavy duty cleaning. The laser process does entail trace amounts of carbon deposit.

Ultrasonically sealed wipes impart an ultrasonic heat process which melds fibers without the need for cutting by knife or the carbon deposit of laser cuts. The result is a cleanroom wipe with lower carbon levels, and a precisely formed, stable edge. Ultrasonically sealed wipes provide the highest grade of particle retention and the most cleanliness.This is the most economical option for less critical cleanroom application but also the most prone to linting or particle shed.
