ITW Texwipe LDPE with Rubber Adhesive Cleanroom Tape (TPR1048BL): quick-tack polyethylene tape for sealing, color coding, and cleanroom build work where moderate adhesion is preferred
TPR Series cleanroom-grade tape family (colors shown are representative; this listing is TPR1048BL blue).
1) Practical solutions in a critical environment
Tape is deceptively high-risk in controlled spaces because it is touched constantly, moved between zones, and pressed onto surfaces that must stay clean and inspectable. A tape that grabs quickly, conforms to irregular shapes, and stores cleanly can prevent a long list of small “workarounds” that create contamination events (ripping on benches, leaving rolls exposed, or substituting construction tape).
ITW Texwipe’s TPR Series is positioned for situations where you need quick tack with moderate adhesion, especially for sealing packaging materials, protecting surfaces, and managing clear visual identification in cleanroom build and maintenance work. The packaging format (press-and-seal cleanroom bags) is intended to keep rolls protected at point of use.
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. For facilities teams and quality teams alike, that matters: continuity of supply, stable documentation, and fewer surprises when you place tape under change control.
2) What it’s for
- PVC/rubber tape replacement in controlled areas where cleaner packaging and cleaner handling matter.
- Asset identification and color coding (tools, carts, bins, shadow boards, and staging locations).
- Surface protection (temporary barrier during maintenance, staging, and move/relocation activities).
- Sealing compound surfaces and packaging materials during cleanroom build-outs and controlled material transfer.
- General cleanroom construction and containment tasks where conformability helps the tape “follow” ducts, visqueen, covers, or irregular hardware.
3) Why should customers consider this tape
- Quick tack with moderate adhesion: Designed to grab quickly without forcing “over-adhesion” where clean removal or repositioning may be needed.
- High conformability: LDPE backing supports sealing around irregular shapes and compound surfaces (ducting, covers, flexible barriers).
- Cleaner introduction and storage: Packaged in reusable press-and-seal cleanroom bags to reduce roll exposure between uses.
- Material screening support: Manufacturer technical data describes the construction as low in halogens, leachable chlorides, and heavy metals (useful for facilities that screen materials).
- Standardized case packaging: Bagged sub-packs support controlled distribution to gowning benches, maintenance kits, or build teams without exposing the full case.
4) Materials and construction
- Backing: Low-density polyethylene (LDPE).
- Adhesive: Rubber (manufacturer technical data describes synthetic rubber in the TPR family).
- Core: 3" HDPE (per manufacturer technical data sheet).
- Latex status: Listed as latex-free.
- Packaging style: Press-and-seal cleanroom bags, intended to protect rolls between uses.
Operator reality check
Tape performance is only half the story. The bigger driver is handling discipline: keep rolls bagged between uses, do not set exposed tape on benches, and avoid aggressive stretch-and-rip tearing that creates jagged edges and film “whitening.” Treat tape as a controlled consumable, not a general tool.

6) Specifications in context
The 1" x 36 yd format is a practical “toolbox width” for facilities and cleanroom build teams: wide enough to create readable color bands and durable seals, but not so wide that it becomes bulky on smaller parts or requires frequent trimming.
A 5.5 mil construction with ~28 oz/in adhesion to steel is often used when you want a tape that bonds quickly yet does not behave like permanent adhesive on many common surfaces. In real operations, this helps with temporary protection, staging labels, and barrier sealing where removal/adjustment is likely during a project window.
If your process includes aggressive disinfectant wipe-downs, pressure, or temperature swings, the published temperature range (-40°F to +190°F) and mechanical properties (tensile/elongation) are the data points quality teams typically use to decide whether to qualify tape for the intended exposure window.
7) Cleanliness metrics (what’s published vs. what teams verify)
Tape is commonly evaluated on residue, edge behavior, and how well it stays protected between uses. Where extractables or particulate counts are not published for a tape family, many facilities treat the tape as a controlled consumable and verify fitness via inspection, residue checks, and procedural controls aligned to their contamination control strategy.

8) Packaging, documentation, and traceability
- Clean handling support: Packaged in press-and-seal cleanroom bags intended to protect the tape between use sessions.
- Case unit (TPR1048BL): 24 bags per case with 2 rolls per bag (48 rolls total); 36 yards per roll.
- Gamma irradiated option (family note): Manufacturer technical data indicates gamma-irradiated versions are available in case quantities by adding “G” to the end of the part number (example given: TPR1048GR-G). Do not assume gamma irradiation unless your ordered part number and paperwork confirm it.

9) Best-practice use (operator-level)
- Keep rolls protected. Open one bag at a time, then reseal between uses. Do not leave exposed rolls on benches or carts.
- Standardize where the tape lives. Assign tape to a cleanroom build kit, maintenance kit, or gowning bench station rather than allowing “free roaming” rolls.
- Use clean tearing technique. Avoid stretching the film before tearing; rip straight and controlled to reduce ragged edges and edge debris.
- Apply with intentional pressure. Press to seat the tape on the surface (especially around irregular contours) without over-rubbing, which can increase residue risk.
- Define removal expectations. If the tape is used on painted, coated, or high-value surfaces, test removal timing and residue checks during qualification before broad rollout.
- For color coding, write the rule down. A color standard is only useful if it is consistent (example: blue = “clean side,” red = “hold,” green = “released,” etc.).
Customer SOP disclaimer
SOSCleanroom provides best-practice guidance and suggested templates to support customer training and continuous improvement. Customers are responsible for developing, approving, validating, and maintaining their own SOPs and safety procedures based on their facility, surfaces, chemicals, products, regulatory obligations, and risk assessments.
10) Common failure modes
- Edge debris from aggressive tearing: Usually a technique issue; retrain tear control and do not stretch-rip.
- Residue complaints: Often tied to surface type, dwell time, pressure, or disinfectant exposure; qualify on your actual surfaces.
- Cross-contamination from shared rolls: Tape becomes a common touchpoint; keep bagged and assign to controlled zones.
- Wrong tape for the job: When abrasion resistance or long-term aisle marking is required, LDPE rubber tape may not be the right mechanism—select based on use case (wear, temperature, removability).
- Color coding drift: If teams do not follow a written standard, colors lose meaning and create confusion during investigations and audits.
11) Closest competitors
Compare cleanroom tapes by mechanism: backing film (LDPE vs. PVC), adhesive chemistry (rubber vs. acrylic), packaging discipline (bagging/traceability), and whether the tape is intended for temporary sealing vs. long-wear marking.
- Micronova Cleanroom PCX Polyethylene Tape: Often compared when teams want a polyethylene tape family for controlled environments with different performance preferences.
- UltraTape polyethylene tapes (rubber adhesive families): Commonly evaluated in controlled-environment build work when customers compare adhesion and backing conformability.
- Texwipe PVC with Rubber Adhesive (TVR Series): A different backing mechanism frequently evaluated when abrasion resistance and cleanroom build marking are central to the use case.
12) Program fit
- Facilities and engineering support: Cleanroom builds, retrofits, and controlled maintenance where the tape must conform and bond quickly.
- Materials management: Color coding and controlled packaging closures for staging, kitting, and transfer steps.
- Contamination control strategy (CCS mindset): When tape handling is written into procedures (where it is stored, how it is dispensed, and how it is removed) to reduce operator-borne contamination risk.
- Multi-site standardization: Consistent part numbering and documentation simplify procurement and reduce substitution risk.
Texwipe pairing note: When tape is used alongside cleanroom wiping and swabbing steps, match supporting consumables (low-linting wipers, cleanroom swabs, and validated cleaning chemistries) to your ISO classification and your approved cleaning/disinfection process window. Nothing is truly “lint-free,” so qualification should focus on low-linting performance that supports your contamination limits.
