Precision Clean-Tear® Precision Clean-Tear® bags are clear and are made from ultrapure resin; the bags are specially contructed to snap open when pulled sharply. This allows quick easy access to cleanroom gloves, medical devices, cleanroom supplies, garments, gowns or other products without having to use scissors or a razor blade. Precision Clean-Tear® bags are available in gauges from .00015" to .004", and in custom sizes from 4" x4" to 38" x 48". A number of variations are available; please refer to the sheet labeled "Available Variations" for a complete list. Precision Clean-Tear® 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.
