CleanMark Labels - Autoclave Color Transition
    CleanMark autoclave indicator labels utilize heat sensitive ink to change color when exposed to temperatures of 121°c or greater. This color change from white to grey creates a visible record that the desired sterilization temperature has been reached during an autoclave cycle. The autoclave indicator labels we manufacture feature a narrow strip of color changing ink on one side leaving enough space to print graphics and text according to your identification needs.

Application spotlight
CleanMark - Autoclave Label Application Spotlight
A pharmaceutical company has developed a new proprietary solution that is stored and administered in syringes. Prior to dosing, syringes are sterilized via autoclave sterilization at standard industry conditions. Due to the nature of their labeling requirements, we constructed a unique custom cleanroom class 100 autoclave label configuration that consisted of pre-printed information, an autoclave indicator box with clear/transparent space within the label that allows for easy viewing of the solution level inside the syringe. The labels are additionally design to adhere to multiple substrates while wrapping seamlessly around the syringes that come in varying circumferences.
Design considerations

In addition to understanding major components and core functions of an autoclave label, the physical form, printing requirements, and aesthetics of a label is equally important. The ability for a company to convey information and effectively package all have profound effects on consumer perception of your brand. As such, any information on cleanroom labels from the form factor to the content on the page should be clearly defined for customers to readily understand. When considering the design space of autoclave labels, we consider the following but not limited to:


  1. What type of printing material do you need for your application?

    • Paper

    • Synthetic (BOPP, PE, PET, etc.)

  2. Will your label need to be processed as a roll or a sheet?

  3. Do your labels need to be clean or clean and sterile?

    • Clean = free of particulate matter

    • Sterile = free of microbial contamination

  4. Does your label require resistance from moisture, high heat, organic solvents, UV radiation, or extreme cold?

  5. Is proof of process sterilization required or desired?

    • What type of sterilization are you performing? 

    • Is box level proof sufficient evidence or is itemized level proof required? 

    • How or where should such evidence be present on the label for clear viewing?

  6. What information is needed on the label?

    • Who is going to read the label? 

    • Does it require tracking and/or tracing capabilities?

    • Are there specific regulatory requirements that need to be present on the label?

    • Do you need to maximize information content on the label?

    • What colors are needed and in what arrangement? 

  7. What are the dimensions and size of the container being used?

    • Is this going on a box or smaller vial?

    • Does the label need to lie flat with it wrapped around?

    • Does the label required non-standard die-cuts

    • Is the surface flat or curved?


Each of the questions listed above will influence the type of label construction we would suggest for your particular application. 

Frequently asked questions
  1. What is sterilization indicating technology (SIT)? 

      • Our indicating technologies are an easy visual guide that allows operators, stakeholders, and any other vested parties to verify their products have undergone sterilization. 

  2. How does ethylene oxide (ETO) compare to vaporized hydrogen peroxide (H2O2) and air plasma sterilization methods?

      • ETO sterilization is a low-temperature technique to sterilize heat and moisture-sensitive tools. A known carcinogenic, ETO requires significant exposure periods often exceeding 8+ hours. However, ETO is far more common and has a greater penetration depth than H2O2. Like ETO sterilization, vaporized hydrogen peroxide is a low-temperature, vacuum-sealed method used to sterilize equipment. As an alternative to ETO, H2O2 is less toxic, and the sterilization process is completed in minutes vs. hours but has less penetration depth. Air plasma is vaporized H2O2 that is ionized to the plasma state via an amplified electric field at normal atmospheric conditions. 

  3. ETO Indicating labels are ethylene oxide sensitive labels that undergo a dynamic color change from purple to green upon exposure. The chromatic intensity of green is contingent on several processing factors, such as equipment preconditioning, ETO/CO2 ratio, sterilization parameters (e.g., duration, RH%, temperature), and water vapor injection. We offer various label options, including stand-alone self-applied labels, custom label integration, and direct on-label printing.

  4. How do I know my products have undergone ethylene oxide sterilization?

      • We apply an indicator ink to any of our labels that will undergo a distinct color change upon appropriate exposure to ETO gas. Our indicator will turn from dark purple to green. 

  5. On what types of surfaces can indicators be placed?

      • With several options for adhesive, cutouts, and form factors, we can place labels on plastic, corrugated cardboard, glass, stainless steel, etc. 

  6. Can you direct print on the labels?

      • Yes! And we also offer printed indicator label options for our customers. 

  7. How are your products verified to work as intended?

      • Our ethylene oxide indicating labels are third-party verified before market release.
