Cleanroom labels engineered for your application.
From material cleanliness and print compatibility to adhesion and durability requirements, we’ll help you identify the right label construction and provide what you need to evaluate it.
Common starting points for cleanroom label projects.
What are cleanroom labels?
Cleanroom labels are identification labels made for cleanrooms and other controlled environments, where ordinary paper labels can shed particles, outgas, or leave adhesive residue.
They use non-shedding, low-particulate synthetic materials, low-outgassing adhesives, and low-residue constructions. They are wound on plastic cores instead of cardboard and can be double-bagged for transfer into the cleanroom.
Common applications
- Semiconductor wafer carriers and FOUPs
- Pharmaceutical vials and sample containers
- Cell culture and media containers
- Cleanroom transfer containers
- Laboratory equipment and instruments
- Bioprocess bags and single-use assemblies
Your application shouldn’t have to fit the label.
The label should be built around your application.
Off-the-shelf labels can work well when requirements are straightforward. But when your surfaces, printing equipment, operating conditions, or cleanroom procedures introduce additional demands, a standard construction may not be enough. That’s where CleanMark’s application engineering and converting expertise make the difference.
Adhesion matched to your surface
We consider surface material, texture, shape, and application conditions to identify adhesive and facestock combinations suited to your requirements.
Compatibility with your printing process
We configure label materials, dimensions, and roll construction around your printing equipment, variable data, and identification requirements.
Performance under your conditions
We select materials for evaluation against the cleaning agents, temperatures, handling, and other exposures your labels will encounter.
Supply configured for your operation
We tailor roll formats, packaging, and documentation requirements to support how labels are received, transferred, and used in your controlled environment.
Labels that fit your equipment and process.
From roll labels to sheets and tags, we configure dimensions, materials, and packaging to work with your existing printers, applicators, and cleanroom procedures.
Roll labelsDie-cut for printing, dispensing, or application.
Continuous rollsContinuous media for your printing workflow.
SheetsSheeted labels for manual application.
TagsIdentification without an adhesive label.
FanfoldedFolded media for compatible equipment.Talk through your application with our engineers.
Discuss your requirements, ask questions, and explore possible approaches. We’ll help you determine the next step for your materials, environment, and process.
One label. From cleanroom handling to liquid nitrogen storage.
A cell therapy application required cryovial identification designed to withstand IPA cleaning and storage at −196 °C without compromising adhesion or readability.
Identification through multiple conditions.
Labels needed to remain attached and readable through cleanroom handling, IPA cleaning, and liquid nitrogen storage. Edge lifting or unreadable barcodes could compromise identification.
Engineer for the complete process.
We consider the vial surface, adhesive bonding, chemical exposure, low-temperature storage, and printer compatibility together—not as separate requirements.
Test under actual conditions.
Evaluate the proposed construction through application, IPA cleaning, freezing, and retrieval, checking adhesion, legibility, and barcode scanning against defined criteria.
Reliable identification through retrieval.
The goal is a label that stays attached, remains readable, and scans reliably after retrieval—with performance confirmed before production approval.
From application requirements to reliable supply.
We help you define the right label, evaluate its performance, and move into production with a specification built around your process.
Understand your application.
We review your surfaces, operating conditions, and performance requirements to identify a suitable label construction and the next steps for evaluation.
Test and verify performance.
Evaluate samples through your actual cleaning, handling, and storage conditions. We provide technical data and engineering support to help you assess performance against your requirements.
Finalize and manufacture.
Once the construction is approved, we confirm specifications, pricing, quantities, packaging, and lead times before manufacturing your labels.
Maintain consistent performance.
We maintain your approved specification for repeat orders and help evaluate changes to your materials, equipment, or process that could affect label performance.

Questions about cleanroom labels.
Can I get samples before committing to production?
Yes, samples are available to test on your own surfaces before you commit to production. Describe your application and an engineer will recommend a construction and send samples suited to your cleaning, storage, and handling process.
What do you need to quote pricing?
Pricing is based on label size, quantity, printing, supply format, and packaging. Send whatever you know. An engineer will confirm the remaining details and prepare the quotation.
What are your minimum order quantities and lead times?
Minimums and lead times depend on the construction, printing, and packaging your application needs. Both are confirmed with your quotation, and stocked constructions typically ship faster than fully custom ones.
How are cleanroom labels different from standard labels?
Standard labels are usually paper on cardboard cores, which can shed particles, outgas, and leave adhesive residue. Cleanroom labels use non-shedding synthetic materials, low-outgassing and low-residue adhesives, and plastic cores, and they can be double-bagged for transfer into a controlled environment.
Can cleanroom labels withstand IPA and other cleaning agents?
Yes, cleanroom labels can be built to stay attached and readable through repeated wiping with IPA, bleach, hydrogen peroxide, and other common disinfectants. The right construction depends on the agent, its concentration, and how often the label is cleaned, and we match the label to that combination.
What adhesive options are available?
Cleanroom labels are available with permanent, removable, and ultra-removable adhesives. Permanent adhesives keep labels attached for long-term tracking, and removable options peel cleanly from stainless steel, glass, and reusable containers without leaving residue. We select the adhesive based on your surface, how long the label stays on, and what it goes through before removal.
How can cleanroom labels be printed?
Cleanroom labels can be printed by thermal transfer, direct thermal, laser, or inkjet, or supplied preprinted. Thermal transfer gives the most durable text and barcodes through cleaning. Direct thermal needs no ribbon but is more sensitive to heat and chemicals. We confirm compatibility with your printer model and ribbon or ink. Explore printable labels →
How are labels packaged for cleanroom entry?
Cleanroom labels can be double-bagged and supplied on plastic cores with synthetic liners, so no paper or cardboard enters the controlled area. Packaging is configured to match your transfer and entry procedures.
Are cleanroom labels sterile?
Cleanroom labels are not necessarily sterile; cleanroom-compatible and sterile are separate requirements. When sterility is required, CleanMark supplies gamma-irradiated sterile labels processed in its Class 100 cleanroom.
What documentation can you provide?
Technical data sheets are available for every CleanMark construction. CleanMark is ISO 9001:2015 certified, and we can provide the documentation your qualification process requires.
