high heat labels

Heat-resistant labeling solutions for critical applications.

Ensure your products withstand the heat with labels engineered for high-temperature environments. Our high heat labels are crafted to endure intense conditions without compromising on performance or readability. Ideal for industries ranging from automotive to aerospace, these labels maintain adhesion and clarity even in the most demanding applications.

Product labeling in high heat.

High heat labels are essential for products that must withstand extreme temperatures. Whether in manufacturing, processing, or end-use environments, these labels are designed to maintain their integrity and readability under intense heat. From automotive components to electronic parts, these labels are engineered to meet rigorous thermal demands.

Key factors for effective labeling.

Effective high heat labels are built with materials and adhesives that resist thermal degradation and maintain adhesion even under extreme conditions. These labels are designed to survive processes such as curing, soldering, and autoclaving without losing functionality.

  • Heat-resistant materials prevent warping or melting in extreme heat.
  • Specialized adhesives maintain strong bonds at high temperatures.
  • Protective coatings shield labels from thermal and chemical damage.
  • Custom sizes and shapes accommodate specific application needs.

Wave Soldering

Electronics heat and immersion.
Wave soldering immerses PCBs in molten solder while exposing top-side labels to 260–300°C heat.

Surface-mount technology exposes labels to fast, intense thermal spikes during reflow oven passes.

Reflow soldering also creates intense short-term thermal spikes during surface-mount electronics production.

Polyimide films and heat-stable adhesives protect traceability through high-temp processing and board washing.

Rubber Vulcanization

High-temp curing and pressure.
Labels must survive >200°C curing cycles, where rubber components are hardened, shaped, and finished.

Vulcanization combines heat, time, and pressure to crosslink rubber in tire and automotive components.

Labels applied pre-cure must withstand the full vulcanization cycle without delaminating or degrading.

Engineered constructions preserve data integrity through chemical exposure, heat, and compression.

Steam Sterilization

Autoclave pressure and heat.
Moisture, heat, and pressure combine in autoclaves—labels must remain readable after repeated sterilization cycles.

Common in labs and healthcare, autoclaves operate at 121–135°C under high steam pressure.

Labels must bond to wet or curved surfaces without smearing, peeling, or fading post-cycle.

Material and adhesive selection ensures readability and traceability through repeated sterilization exposure.

Curing Ovens

Paint and powder coating.
Labels must withstand 150–220°C bake cycles after paint or powder is applied to metal parts.

Automotive parts often enter paint or powder coating lines, then bake at high heat to cure finishes.

Labels must resist bubbling, discoloration, and adhesive bleed during elevated oven temperatures.

Durable films and heat-stable topcoats preserve barcode readability through curing and finishing stages.

Extreme Heat

Heat exposure over 300°C.
Tracking labels that survive sustained exposure in kilns, annealing lines, or metal heat treatment.

Processes like sintering, forging, and annealing expose parts to 400°C–600°C+ thermal environments.

Labels must resist oxidation, shrinkage, or adhesive failure under intense, sustained radiant heat.

Specialized films and cured coatings allow traceability through the most punishing thermal cycles.

Test your toughest process—request a high heat label sample engineered to endure extreme temperatures, curing lines, and thermal shock.

Pre-printed labels using UV-cured inks resist heat-related image distortion, preserving clarity through prolonged or extreme heat exposure.

Label Construction

We build high heat labels using stable face stocks like polyimide and high-temp polyesters, paired with heat-resistant adhesives. Constructions are designed to remain intact at continuous temperatures above 300°F, with options that withstand even higher peaks during curing, soldering, or processing.

Durability Testing

Labels are tested across a range of operating and peak temperatures, including sustained exposure and thermal cycling. We validate adhesive hold, material stability, and image integrity under real production conditions to ensure consistent performance.

Print-on-Demand Labels

Thermal transfer is a common method for high heat applications, especially when paired with resin ribbons designed for extreme conditions. We guide material and ribbon selection to ensure printed data stays intact through ovens, hot surfaces, or direct contact with heated components.

Pre-Printed Labels

For long-term heat exposure, we offer pre-printed solutions using cured inks and abrasion-resistant finishes. Our production systems support serialized sets, small text, and high-contrast imaging—engineered for high-visibility labeling in manufacturing, aerospace, and electronics environments.

Sterilization-safe labeling doesn’t stop with the label itself—it’s about making sure your workflow, print process, and hardware all align. Our label solutions are compatible with a wide range of printing systems, including thermal transfer printers, laser printers, and fully automated label applicators. If you’re printing in-house, we’ll guide you toward face stocks and coatings that match your specific printer model, ribbon type, and print resolution needs.

In labs and cleanrooms where sterilization is required, hardware selection often impacts label durability. For instance, thermal transfer printing combined with resin ribbons offers enhanced chemical and heat resistance—critical for autoclave or chemical sterilant workflows. When automation is part of the process, we ensure label materials meet the physical requirements of robotic handling, high-speed printing, or tight label tolerances. No matter how you’re printing—whether it’s a single workstation or a full-scale automation line—our labels are designed to work with your equipment, not against it.

Converting & Finishing

Thermal exposure testing reaches up to 600°C to simulate extreme environments. We validate label integrity through cycles of dry heat, autoclave steam, and other heat sources. Testing ensures labels retain adhesion, remain legible, and resist discoloration at elevated temperatures.

Proven under pressure, curing and extreme heat.

Labels exposed to high temperatures need more than basic heat resistance—they require engineered materials that remain legible, bonded, and stable.
