Sterilization Indicator Labels by Process Type

CleanMark provides sterilization indicator labels designed around the specific sterilization process, handling requirements, and operational workflow involved.

Autoclave indicator labels

CleanMark’s autoclave sterilization indicators show successful autoclave sterilization with a light to dark gray color change and/or text appearance. They’re heat, pressure, and moisture resistant to withstand harsh autoclave conditions.

Gamma indicator labels

Our gamma sterilization indicators resist radiation degradation, preserving legibility and ensuring good adhesion. A yellow to red color change and/or text appearance is a quick-glance indicator of successful gamma sterilization.

EtO indicator labels

Durability against prolonged moisture, heat, and chemical exposure is a key feature of CleanMark’s EtO sterilization indicators. An easy-to-read color change from green to purple indicates successful gamma irradiation.

When sterilization visibility cannot be left to chance

Sterilization indicator labels are often used when:

  • Visual confirmation of sterilization exposure is required
  • Sterilized and non-sterilized materials must be differentiated quickly
  • Workflow verification supports quality or compliance processes
  • Batch identification and traceability are important
  • Labels must remain adhered and legible after sterilization exposure
  • High-volume workflows depend on fast, reliable process identification

Where sterilization verification matters most

Sterilization indicator labels help support process verification, workflow control, and traceability throughout regulated sterilization environments.

Pharmaceutical manufacturing

Support sterilization verification, batch identification, and workflow control throughout regulated production environments.

Medical devices

Help distinguish sterilized and non-sterilized products while supporting traceability and sterilization process verification.

Healthcare & hospitals

Provide fast visual identification throughout surgical, diagnostic, and patient-care sterilization processes.

Laboratories & research

Support sterilization verification and workflow separation throughout laboratory preparation and testing environments.

How we engineer label performance for your application

Label performance depends on how materials interact with your environment, surfaces, application processes, and workflow requirements.

Chemical exposure

Resistant facestocks and coatings protect printed information from solvents, disinfectants, and harsh cleaning agents.

Cleaning cycles

Abrasion-resistant materials withstand repeated wipe-downs without degrading readability or adhesion.

Temperature conditions

Materials are selected to remain stable across cold storage, ambient, and high-heat environments.

Removal requirements

Adhesives are selected based on whether labels need to remove cleanly or remain permanently bonded over time.

Surface type

Adhesives are matched to plastics, metals, glass, textured materials, and other challenging surfaces.

Application method

Label constructions are designed to support manual, semi-automated, and automated application processes.

Print method

Topcoats are selected to support durable, legible printing across thermal transfer, direct thermal, laser and inkjet systems.

Size considerations

Label dimensions are matched to available surface area, barcode requirements, and readability needs.

Shape requirements

Label shapes are designed around containers, equipment, packaging, and workflow constraints.

Configure indicator placement around your label

Indicating ink can be integrated into custom label layouts that preserve printable space for variable product information, traceability data, barcodes, and operational identification requirements.

When sterilization status could not be left to chance

A medical device manufacturer approached CleanMark looking for a more reliable way to visually identify sterilized products moving through production and packaging workflows.

Their teams needed a faster and more reliable way to distinguish sterilized from non-sterilized products without slowing workflow efficiency or creating uncertainty during packaging, handling, and distribution.

The challenge extended far beyond simply creating a color-changing label.

The customer needed a blank label with a gamma sterilization indicating strip positioned along the right side of the label. The remaining label area needed to remain printable so variable product information could be added during manufacturing based on the specific product and production run involved.

The labels also needed to integrate into a regulated manufacturing workflow involving sterilization exposure, handling, storage, traceability requirements, and high-volume operational throughput. Reliable adhesion, clear indication, print compatibility, and long-term readability all needed to work together consistently.

CleanMark evaluated the full operational workflow surrounding the application including sterilization method, environmental exposure, handling processes, print requirements, adhesive performance, and how the labels moved throughout the production environment.

The result was a sterilization indicator labeling solution engineered to provide reliable visual indication, dependable adhesion performance, and consistent printability throughout the workflow.

What began as a process verification challenge evolved into sterilization indicator solutions now supporting pharmaceutical manufacturing, medical devices, healthcare, laboratories, and other regulated sterilization environments where workflow control and traceability matter.
