TX5816 (TexWrite® 22) — blue 8.5" x 11" loose sheets with 3-hole punch for controlled-document binders.
Practical solutions in a critical environment
If your line relies on travelers, batch records, equipment logs, and controlled binders at point-of-use, “regular office paper” becomes a contamination source:
fibers, dusting at cut edges, toner flake, and ionic contributors that show up later as corrosion risk or surface residues. TX5816 is designed as a cleanroom
documentation sheet for situations where you want binder-ready pages without punching in-house (and without introducing loose chads into gowning areas,
pass-throughs, or workstations).
This is especially relevant for document sets that live on stainless carts, inside laminar flow hoods, or in tool cribs where pages are frequently turned,
removed, and reinserted.
What this product is used for
- Controlled binders for SOPs, maintenance logs, calibration records, and equipment history kept near the process.
- Traveler packets and batch record inserts where 3-hole punch alignment matters for clean, repeatable binder handling.
- Cleanroom manuals, work instructions, and shift handoff documentation where color-coding helps segregate projects/areas.
- Printing and copying in standard-duty and high-speed laser printers and photocopiers (per manufacturer guidance).
- Offset printing and note taking for controlled environments where paper cleanliness consistency is part of the contamination-control plan.
Why customers consider this product
- Binder-ready without in-house punching. Eliminates paper chads and edge damage that often show up as “mystery debris” during line clearance.
- Designed to reduce paper shedding versus conventional bond. TexWrite® 22 is engineered for controlled documentation use.
- Printer/copier compatibility. Strong heat resistance and toner adhesion for laser printing and photocopying (manufacturer-stated).
- Color discipline for document control. Blue sheets help clearly flag cleanroom-controlled documents or separate areas/shifts/projects.
- Continuity and documentation discipline. For over 35 years, SOS and Texwipe have been close partners, and SOSCleanroom is the authorized Master Distributor of ITW Texwipe for the United States market.
- Made in USA (per Texwipe TDS).
Materials, composition, and build
TX5816 is a cellulose paper with a polymer reinforcement (manufacturer description). Formulated without inorganic fillers such as calcium carbonate, titanium dioxide, or aluminum silicate (manufacturer-stated). The polymer reinforcement is latex-free with “no natural latex binders” for the TexWrite® 22 line.
These sheets are intended to behave more consistently under typical documentation handling—page turning, binder insertion/removal, printing/copying—while
reducing dusting at edges and minimizing the “powdery” feel that office bond can develop after repeated handling in low-humidity rooms.

What it means on the floor |
| Particles (>0.5 µm) | 4.8 million particles/m² | Benchmark for paper shedding under minimal stress; helps compare document materials in qualification. |
| Sodium (ions) | 85 ppm | Useful when tracking ionic contributors tied to corrosion risk or sensitive assemblies. |

Note: Texwipe states these are typical analyses and not product specifications.
Ink/toner behavior: solvent resistance of inks (IPA, ethanol, quats) depends on the writing instrument or printed ink/toner system. If solvent wipe-down of paperwork is part of your practice, qualify the full system: paper + ink + dry time + solvent + handling pattern.
Packaging, sterility, traceability, and country of origin
- Packaging: 250 sheets per inner pack; 10 packs per case (2,500 sheets total).
- Cleanroom packaging: stated by the manufacturer.
- Sterility: not stated. “Autoclavable” is stated by Texwipe; qualify the post-autoclave handling method in your quality system if autoclaving is planned.
- Country of origin: Made in USA (per Texwipe TDS).
- Traceability / documentation: COA/COC statements not published on the SOS listing; confirm requirements at time of order.
Best-practice use
- Receiving/QA cue: check hole alignment, edge finish, and dusting at punch points. Paper chad residue in a pack is a red flag.
- Binder discipline: use clean, dedicated binders; treat them like any reusable tool—wipe exterior surfaces and control where they sit.
- Printing workflow: print in a controlled print area and allow toner to cool/set before stacking.
- Ink selection: qualify the specific pen/marker and dry time on TX5816 under your actual solvent and glove conditions.
- Line clearance habit: verify no torn hole edges, no loose inserts, and no loose pages in cart trays before closeout.
- Autoclaving: follow Texwipe’s paper autoclave TechNote and qualify post-cycle handling, cooling, and storage.
Common failure modes
- Hole tear-out and edge fray: overfilled binders and rough ring edges can tear punched holes and create blue paper debris.
- Toner offset/flake: printing then immediately stacking or folding can transfer toner.
- Smearing after solvent contact: driven by pen/marker choice, inadequate dry time, or aggressive wipe technique.
- Uncontrolled binder migration: a cleanroom-qualified sheet can still become contaminated if the binder is not controlled.
- Autoclave warping/curling: qualify your cycle and storage method.
Closest competitors

Critical environment fit for this product
Texwipe states TX5816 is appropriate for ISO Class 3–8 (also Class 1–100,000 and EU Grade A–D). The most important fit question is not “can it enter the room,” but “how will it be handled.” Build your qualification around real failure modes: punch-edge stress for frequently handled binders, toner set time for high-volume printing.
SOSCleanroom note about SOPs
The Technical Vault is written to help customers make informed contamination-control decisions and improve day-to-day handling technique.
It is not your facility’s Standard Operating Procedure (SOP), batch record, or validation protocol.
Customers are responsible for establishing, training, and enforcing SOPs that fit their specific risks, products, equipment, cleanroom classification, and regulatory obligations.
Always confirm material compatibility, cleanliness suitability, sterility requirements, and acceptance criteria using your internal quality system and documented methods.
If you adapt any technique guidance from this entry, treat it as a starting template. Your team should review and approve the final method, then qualify it for your specific surfaces, solvents, cleanliness limits, inspection methods, and risk profile.
