These autoclave-resistant labels can be used to identify various containers and surfaces that will undergo autoclaving and dry heat sterilization, such as glass bottles, tubes, plates, metal trays, plastic bags, and more. Steri-ThermoTAG labels resist elevated temperatures up to +150°C (+302°F), gamma irradiation up to 50 KGy, as well as ethylene oxide sterilization. Compatible with most common brands of thermal-transfer printers.

Frequently Asked Questions

Yes, Steri-ThermoTAG labels are thermal-transfer printable and require a ribbon to be printed. To achieve the proper printout, these labels require a smudge-proof RR-class ribbon of the same width or larger.

No, Steri-ThermoTAG labels can only be printed with thermal-transfer printers. For laser and inkjet printable autoclave-resistant labels, we suggest Steri-LazrTAG and Steri-JetTAG.

Yes, we offer three kinds of autoclave tape. Our TAUT-class autoclave-resistant tape can be printed with thermal-transfer printers, our STRAT-class tape, which is perfect for use as an indicator of steam sterilization, and our TARG-class removable autoclave-resistant tape is easy to hand-tear without cutting instruments.

Yes, Steri-ThermoTAG labels can withstand high-heat conditions, up to temperatures of +150°C.

No, Steri-ThermoTAG labels are not suited for deep-freeze or cryogenic applications. For thermal-transfer labeling solutions that are both autoclave-resistant and withstand storage in cryogenic conditions, click here.

No, Steri-ThermoTAG labels are not chemical-resistant. For autoclave-resistant labels that will resist exposure to alcohols such as ethanol and isopropanol, click here.

Yes, Steri-ThermoTAG is offered in a variety of colors.

No, AUTT-class labels have a permanent adhesive that is not made for easy removal. For removable autoclave-resistant thermal-transfer labels, we offer our AUTR-class.

No, AUTT-class labels do not have an indicator strip that changes color when the labels have been autoclaved. For Steri-ThermoTAG labels with an indicator strip, we offer our SAUP-class labels.

No, AUTT-class labels are not designed to be applied over existing labels. For covering-up obsolete or inaccurate labels, we recommend our BOA-class blackout thermal-transfer labels.

No, Steri-ThermoTAG is not offered in piggyback format. However, we do offer thermal-transfer piggyback labels that are suitable for autoclave applications, see here.

No, we do not offer a laminated version of Steri-ThermoTAG. For permanent thermal-transfer autoclave-resistant labels that come with a laminate for added protection, we suggest our SLPA-class Print-N-Shield™ labels.

No, we do not offer a clear version of Steri-ThermoTAG. For transparent thermal-transfer autoclave-resistant labels, we suggest our GANA-class Cryo-OmniTAG labels.

Barcoding or label design software can be used to create templates that conform to the size of your label. You can then insert design elements within the template for easy printing.
