Paper that is not cleanroom compatible typically generates a high level of particulate due to its high fiber content. We stock a variety of cleanroom paper options that offer the following features and benefits: Low levels of particles, nonvolitle residue (NVR), and ion extractables - Class 10 Cleanroom compatible and higher - Double Bagged.
