Product Description
Unitek CRP0760-3 Clean-Write® 22 lb Cleanroom Paper — 8.5" x 11" Loose Sheets (250 sheets/pack; 10 packs/case)
CRP0760-3 is saturated-cellulose cleanroom paper for technician documentation inside controlled environments where office-grade paper creates avoidable paper dusting, residue, and particle-shedding risk. It is intended for batch/lot travelers, equipment logs, inspection checklists, maintenance notes, QA/QC sign-offs, and process documentation that must stay legible and contamination-aware at the bench. The Clean-Write® construction is manufactured with a cellulose base sheet saturated with synthetic latex to substantially reduce particle generation associated with standard papers while supporting practical printer/copy workflows.
Use this product when you want to standardize documentation flow into and within cleanrooms: cleanroom-packaged stationery helps reduce uncontrolled fibers, debris, and handling variability that can show up as rework, smears, or foreign material during reviews.

Low particle generation — and the reality check
This paper is designed to substantially reduce particle generation versus standard papers for cleaner documentation in controlled environments. Even so, no paper product is truly zero-shedding in real operations. Treat cleanroom stationery like a contamination-controlled component: control how it is introduced, how long it stays exposed, and what touches the sheet during use.
Practical cleanroom use guidance (technicians and engineers)
- Open-stack control: Do not fan sheets. Fanning and edge-tapping are common causes of paper dusting and particle mobilization.
- Documentation-only zone: Keep paper off critical product surfaces. Use a dedicated clipboard/binder station so sheets do not pick up residues from benches.
- Glove discipline: Keep gloves dry. Solvent-wet or DI-wet gloves are a primary driver of smearing, ink transfer, and edge softening.
- Controlled handling: Lift sheets cleanly; avoid sliding across rough benches or garments, which can shed fines and abrade edges.
- Printer/toner qualification: If printing inside controlled areas, qualify the printer and consumables to avoid toner dust and uncontrolled residues that can defeat the purpose of cleanroom paper.
Compatibility and wipe-down notes
- IPA exposure: Typical non-volatile residue (NVR) is published for isopropyl alcohol; practical wipe-down tolerance of loose sheets is not published. If your SOP requires IPA contact, qualify for legibility and smearing under your dwell time and handling method.
- DI water / aqueous exposure: Typical NVR is published for deionized water; practical wipe-down tolerance is not published. Validate for swelling, wicking, and residue/transfer risk before standardizing aqueous handling.
- Wipe-down technique (if permitted by your SOP): Avoid saturating sheet edges and corners. Edge-wicking can soften fibers and increase paper dusting during handling.
Typical performance characteristics
Features- Smearing / ink transfer: Usually driven by wet gloves, solvent contact, or stacking sheets before ink fully dries. Prevent with dry-glove discipline and controlled dry time before bundling.
- Paper dusting / edge abrasion: Common with fanning, edge-tapping, and sliding sheets across benches. Prevent with stack control and lift-and-place handling.
- Particle shedding from rough handling: Aggressive flipping, dragging corners, or rubbing against garments can mobilize fines. Prevent with controlled movements and dedicated staging surfaces.
- Residue carryover: Transfer from benches, sleeves, or contaminated gloves. Prevent by keeping sheets out of process-contact zones and maintaining documentation-only handling.
- Static attraction: In low humidity, paper can attract fines. Prevent by following site ESD controls and avoiding rubbing sheets against packaging or garments.
