Autoclave and Sterilization Labels

Consolidated Printing Supplies builds custom labels for parts, trays, vials, and containers that go through steam autoclave, ethylene oxide (EtO), and gamma sterilization. We match the face stock, adhesive, and print method to your exact cycle, then send free samples so you can test them in your own process before you order.

Why labels fail in sterilization

Most sterilization label failures come from one of three places:

Adhesive. Heat and steam soften standard adhesives, so edges lift, labels slide, or adhesive oozes past the edge.
Face stock. Paper absorbs moisture and delaminates. Some films shrink or wrinkle after repeated heat.
Print. Standard inks and wax ribbons can smear, fade, or wash off, leaving barcodes that will not scan.

Fixing one of these is not enough. The label has to be built as a system for the cycle it will see.

What each sterilization method demands

Steam autoclave

Steam autoclaves typically run at 121°C (250°F) or 132 to 134°C (270 to 273°F) under pressure, often for many repeated cycles. The label needs a heat-stable film, an adhesive that holds through moisture and pressure changes, and print that will not soften.

Ethylene oxide (EtO)

EtO runs at lower temperatures but combines gas exposure, humidity, and long aeration times. Adhesive and ink compatibility with the gas and the humidity matter more than peak heat.

Gamma and e-beam

Radiation adds little heat, but it can yellow or embrittle some plastics. Polypropylene is especially prone to this. Polyester and polyimide films generally hold up better, and the print and adhesive need to stay stable at your dose.

How we build sterilization labels

Face stock: polyester for most autoclave work, polyimide for higher heat.
Adhesive: high-performance adhesives selected for heat, moisture, and the surface you are labeling, whether that is stainless steel, glass, plastic trays, or wrapped packs.
Print: thermal transfer resin on a topcoated film for printing on your own printer, or pre-printed graphics, plus variable data such as barcodes and serial numbers.
Documentation: UL 969 recognized and FDA-compliant material options, with documentation available on request.

What we need to recommend a label

Sterilization method and cycle: temperature, time, and number of cycles
What the label goes on: material, shape, and whether it is curved or flat
How it is printed: your printer model, or pre-printed by us
Other exposures: cleaning chemicals, washers, freezing, or cryogenic storage
Label size and approximate annual quantity

Test it free, in your own process

We send free material samples so you can run them through your actual autoclave or sterilization cycle before committing. Once a construction passes, standard production typically takes 7 to 10 business days, with rush service available. We run everything from short prototype runs to programs of 1,000,000+ labels.

Frequently asked questions

Can a label survive repeated autoclave cycles?

Yes, with the right construction. A polyester or polyimide face stock with a high-temperature adhesive and resin print is built for repeated steam cycles. The only reliable proof is a test in your own autoclave, which is why we send free samples first.

Can I print sterilization labels on my own thermal transfer printer?

Yes. We pair a topcoated film with a resin thermal transfer ribbon matched to your printer so barcodes and text survive the cycle.

Will a standard paper label work in an autoclave?

Usually not. Paper absorbs steam, weakens, and delaminates, and standard adhesives soften. Synthetic films are the normal starting point.

Do you make labels for EtO and gamma sterilization?

Yes. Each method stresses a label differently, so tell us the method and we will select materials for it.

Do you provide material documentation?

Yes. UL 969 recognized and FDA-compliant material options are available, with documentation on request.

What is the minimum order?

Typically 2 cases, depending on label type and material.
