Whether you’re solving a performance problem, qualifying a new application, adapting to changing requirements or looking for a more reliable supplier, we start by understanding what the application requires.
Residue, particle shedding, poor adhesion, print failure or other performance issues.
Define the requirements and reduce unnecessary trial-and-error before scale-up.
A new surface, environment, process, quality requirement or operating condition.
Inconsistent performance, long lead times, poor responsiveness or limited technical support.
In a controlled environment, the label has to maintain identification without creating new problems for the process around it.
Maintain adhesion through the environmental, handling and cleaning conditions the application requires.
Come off sensitive containers, equipment or surfaces without leaving unwanted adhesive residue.
Keep printed information, barcodes and variable data legible through handling, cleaning and environmental exposure.
Materials, adhesives, liners and packaging should be considered in the context of the controlled environment.
Particles, material emissions and identification loss can affect contamination control and process reliability.
These considerations matter across contamination-sensitive applications including semiconductor manufacturing, pharmaceutical production, medical devices, biotechnology and laboratory environments.

| Materials | Selected with particle generation, contamination control and application requirements in mind. | Selected primarily for general-purpose labeling requirements. |
| Adhesive behavior | Engineered around permanence, clean removal and surface requirements. | Designed primarily around general adhesion and removal. |

We evaluate the variables that matter, understand how they interact and engineer both the construction and geometry around what the application requires.
Environment, surface, identification and workflow requirements help determine the materials and construction.

Die-cut labels supplied on rolls for printing, dispensing or application workflows.
Continuous material configured around printing and use requirements.
Sheeted labels for manual application or workflows that do not require roll-fed dispensing.
Durable tags for identification and traceability where an adhesive label is not the preferred format.
Fanfolded labels for printers and application systems configured to use fanfolded media.
Available labeling area, surface geometry, information requirements and application method all influence final label size, shape and layout. Custom dimensions, shapes, corner radii and die-cut geometries can be engineered around the application.
Usable space, size constraints and clearance.
Flat, curved, cylindrical or irregular surfaces.
Barcodes, variable data, text and symbols.
Manual, semi-automated or automated.
From vials and tubes to carriers, packaging and process containers, label size and geometry are configured around the application.
A label can be right for the surface, environment and geometry and still create problems if it doesn’t print, dispense, apply or move into controlled use reliably.
The label has to produce clear, durable identification.
The roll and liner have to run reliably through the equipment.
The label has to reach the surface correctly and consistently.
The finished identification has to remain reliable through handling and cleanroom entry.
In the 1990s, a semiconductor manufacturer was experiencing adhesive residue on wafer boxes in a contamination-sensitive environment.
The issue wasn’t simply adhesion. Materials, particles, residue, handling and identification performance all interacted.
That early work helped shape the application-first approach CleanMark still uses when engineering cleanroom labels.

Quick answers to the most common questions about cleanroom labels.
Cleanroom labels are labeling solutions designed for contamination-sensitive controlled environments. Their materials, adhesives, liners, printing and packaging are selected around the application to help reduce risks such as particle generation, adhesive residue, material emissions and identification failure.
Cleanroom compatibility depends on how the label performs in its intended environment. Factors can include particle generation, material and adhesive behavior, clean-removal requirements, chemical exposure, print durability, liner performance and controlled handling or packaging.
Depending on their construction, general-purpose labels may introduce particles, residue or material emissions, or lose adhesion and readability after cleaning, chemical exposure, moisture, temperature changes or routine handling.
Cleanroom labels are designed around contamination-sensitive environments. Sterile labels are sterilized and packaged to maintain sterility. Depending on the application, a label may need to be cleanroom compatible, sterile or both.
Variables can include cleaning agents and cycles, chemical exposure, temperature, humidity, surface material, removability, printing technology, barcode durability, application method, automation, liner performance, roll configuration, packaging and storage.
The liner can influence particle generation, dispensing reliability, application performance and handling. Liner material, visibility, release behavior and compatibility with manual or automated application may all matter.
Outgassing is the release of volatile compounds from materials over time. In contamination-sensitive environments, material or adhesive emissions may contribute to contamination, equipment or product-quality concerns.
Cleanroom label constructions can support common printing technologies including thermal transfer, direct thermal, laser and inkjet where appropriate. Printer, ribbon or ink, facestock, topcoat and application requirements should be evaluated together.
Yes. Label size and shape can be engineered around the available labeling area, surface curvature, container or equipment geometry, information and barcode requirements, and the way the label will be applied. Depending on the application, this can include custom dimensions, corner radii and custom shapes.
Packaging can be configured to support controlled handling, shipping, staging and transfer into contamination-sensitive environments, including double-bagged configurations where required.
CleanMark has supported cleanroom and controlled-environment labeling applications since the 1990s. Early semiconductor contamination challenges helped shape the application-first approach used today.
