Precision Clean ® II Precision Clean® II bags have excellent clarity, and are made from ultrapure resin. They are intended for packaging semiconductor wafer boxes, medical devices, cleanroom gowns, gloves or wipes or for any other product requiring a similar level of surface cleaniness. These bags are available in gauges from .0015" to .010", and in custom sizes from 2" x 3" to 47" x 48" (for flat bags; we also offer gusseted bags). A number of variations of Precision Clean® II film and bags are available, including rollstock in tubing and center form; please see the "Available Variations" table for further information. Precision Clean® II bags are manufactured and packaged in our Class 10 (M2.5) cleanroom; they are available printed or unprinted, and are suitable for sterilization by gamma radiation or ethylene oxide.
