Cleanroom office supplies are specially designed for use in controlled environments where minimal particle release is required. Cleanroom paper ring binders are made of low-emission materials and are suitable for secure documentation within cleanrooms. They are available in common formats such as DIN A4 and A5 and, depending on the version, are qualified for cleanroom classes up to ISO 5 or ISO 6. Typical areas of application include logging, labeling and creating work instructions in sensitive production environments
