Sterile labels engineered around your application.

Sterile labels are sterilized and packaged for use in aseptic, sterile and contamination-controlled workflows. We evaluate the label construction, packaging, printing, application and sterilization together—so identification remains reliable throughout your process.

Not sure of the exact construction or configuration? You don’t need to be.

We start where you are.

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 your process requires.

Something isn’t working

Poor adhesion, print failure, packaging or transfer issues, sterilization-related performance problems or other performance challenges.

New application or qualification

Define requirements and reduce unnecessary trial-and-error before scale-up.

Requirements have changed

A new surface, environment, process, quality requirement or operating condition.

Supplier performance isn’t meeting expectations

Inconsistent performance, long lead times, poor responsiveness or limited technical support.

A sterile label has to do more than arrive sterile.

The label has to maintain reliable identification while fitting into the packaging, transfer, printing, application and sterile-use processes around it.

Arrive in the required sterile state

Sterilization and packaging are considered around your process and handling requirements.

Stay securely in place

Maintain adhesion through the conditions the label encounters during use.

Remain readable

Keep printed information, barcodes and variable data legible throughout the required service life.

Support sterile transfer and use

Packaging and configuration should fit the way labels enter and are used within the sterile workflow.

When identification performs as intended, the important work around it can continue uninterrupted.

Sterilizing the label is only part of the solution.

A sterile label becomes part of a larger aseptic workflow. Construction, packaging, transfer, printing, application and sterilization requirements all need to be considered together.

What are sterile labels?
Sterile labels are sterilized and packaged for introduction into sterile or aseptic workflows. CleanMark’s sterile-label offering uses gamma sterilization, with the construction and format selected around the intended use.

The right label starts with the application.

We evaluate the variables that matter, understand how they interact and configure the label around those requirements.

Label construction

The construction is engineered around sterile-use requirements.

Sterilization, environment, surface, identification and workflow requirements help determine the materials, adhesive and overall construction.

Application variableWhat we evaluateWhat it can influence
SterilizationGamma exposure, process requirements and material compatibilityFacestock, adhesive and print system
EnvironmentSterile or aseptic conditions, cleaning, temperature, moisture and handlingConstruction and print durability
SurfaceMaterial, geometry, surface characteristics and removabilityAdhesive and label geometry

The right construction comes from the complete application — not sterilization alone.
How the solution is configured

Sterile doesn’t define the construction. Your application does.

Construction, format and configuration are selected around the environment, surface, printing equipment and workflow.

Construction options

Paper-based sterile labels

When a paper construction provides the required performance and workflow compatibility.

Cleanroom-compatible sterile labels

When contamination-control considerations also influence material and construction selection.

Core, rewind, liner, spacing and equipment compatibility can be evaluated together.

Packaging

Packaging is defined around sterilization, transfer and handling requirements.

Fitting the label to your application

Size and shape are engineered around the container and process.

Available labeling area, surface geometry, information requirements and application method all influence final label size, shape and layout.

Available labeling area

Usable space, size constraints and clearance.

Surface geometry

Flat, curved, cylindrical or irregular surfaces.

Information requirements

Barcodes, variable data, text and symbols.

Application method

Manual, semi-automated or automated.

Engineered around the container.

Container geometry and available labeling area are considered together with identification needs and the way the label is applied.

The process determines how the label needs to work.

Printing, dispensing, application, packaging, sterilization and sterile transfer do not always occur in the same order. We evaluate how these requirements fit together in your actual workflow.

Sterile compounding labeling application

Closing the final nonsterile gap—without changing the labeling workflow.

The problem

A sterile compounding organization used continuous-roll labels with automated printers and applicators for IV bags and syringes. The label rolls remained one of the final nonsterile components entering the operation.

What the application required

The labels needed to be supplied in a sterilized format without requiring a redesign of the existing printing and application process.

Common questions.

Quick answers about sterile labels, gamma sterilization, construction, configuration and workflow.

What are sterile labels?

Sterile labels are labels that have been sterilized and packaged for introduction into a sterile or aseptic workflow. The label construction and supplied configuration still need to be appropriate for the intended use.

How are CleanMark sterile labels sterilized?

CleanMark’s sterile-label offering uses gamma sterilization. Construction, packaging and sterilization requirements are reviewed together in the context of the customer’s process.

Can sterile labels be paper-based?

Yes. Sterility does not by itself determine the facestock. Depending on the use case, a paper-based or cleanroom-compatible construction may be appropriate.

Can sterile labels also be cleanroom compatible?

Yes. Sterility and cleanroom compatibility describe different requirements. A label can be sterile, cleanroom compatible, or both depending on the process requirements.

What is the difference between a cleanroom label and a sterile label?

Cleanroom labels are designed around contamination-control requirements for controlled environments. Sterile labels are supplied in a sterilized state for introduction into sterile or aseptic workflows. Depending on the use case, a label may need to meet one requirement or both.

What is the difference between sterile labels and sterilization indicator labels?

Sterile labels are supplied in a sterilized state for use in sterile or aseptic workflows. Sterilization indicator labels are designed to provide visual evidence of exposure to a sterilization process. They serve different purposes.

Can sterile labels be supplied as roll labels, continuous rolls or sheets?

Yes. Sterile labeling solutions can be supplied as die-cut roll labels, continuous material or sheets depending on printing, dispensing, application and handling requirements.

Can sterile labels support barcodes and variable data?

Printing technology, ribbon or ink, construction, barcode requirements and expected use conditions can be evaluated together to support readable identification.

Will sterile labels work with our existing printer or applicator?

Existing equipment can be evaluated as part of the requirements review. Core, rewind, liner, spacing, printing technology and application method can all influence compatibility.

What can be customized?

Depending on the use case, construction, dimensions, shape, roll configuration, printing compatibility and packaging can be evaluated and configured around the process.

What sterilization documentation is available?

Documentation requirements should be established during requirements review. Available records and supporting information can vary based on the solution and sterilization program.
