Why Use Cleanroom-Grade Paper?
Standard office paper is manufactured without particle-generation controls and sheds fibers, dust, and particles that can contaminate ISO-classified environments, ESD-sensitive assemblies, and pharmaceutical or medical device production areas. Cleanroom-grade paper like the Columbia PA22LF-CRE11 is produced in controlled conditions, cut with low-particle edges, and packaged to minimize contamination before use. It is required or strongly recommended wherever standard paper would compromise environmental cleanliness standards.
Industries & Applications
- ISO-classified cleanroom documentation and batch record keeping
- Pharmaceutical and biopharmaceutical manufacturing
- Medical device manufacturing and assembly

Frequently Asked Questions
What is the difference between the 20lb, 22lb, and 28lb Columbia cleanroom papers?
The weight designation refers to the paper basis weight — heavier paper is thicker and more opaque. The 20lb (PA20LF-CRE11) is a lighter sheet suitable for high-volume printing; the 22lb (PA22LF-CRE11) is the standard weight for general cleanroom documentation; the 28lb (PA28LF-CRE11) is heavier and more durable for documents that will be handled frequently. All three are low-lint cleanroom grade.
Can I use this paper in a standard laser or inkjet printer inside a cleanroom?
Yes — cleanroom paper is designed to be compatible with standard office printers. Printers used inside cleanrooms should themselves be qualified for cleanroom use, as standard printers can be significant particle generators. Many facilities place the printer outside the cleanroom and bring printed documents in through a pass-through.
What ISO classification is this paper suitable for?
Columbia cleanroom papers are appropriate for a range of ISO classifications depending on your facility's qualification process. Consult your cleanroom validation documentation and paper qualification data for your specific ISO class requirements.
Why is the paper cream-colored rather than white?
The cream color is characteristic of Columbia's cleanroom bond paper line and helps distinguish cleanroom-grade paper from standard white office paper, reducing the risk of accidentally introducing standard paper into a controlled environment.
How is the paper packaged?
Each case contains 2500 sheets. Columbia cleanroom paper is packaged to minimize particle exposure before use — keep sealed until ready to introduce into the cleanroom environment.
