High temperature labels
Choose the right material for your industrial applications
When printing high temperature labels, you can choose from a range of materials, including polyester, polypropylene and polyimide. The application, surface and required lifespan determine the most suitable material.
Why use high temperature labels?
Industrial environments often require labels that can withstand demanding conditions. Processes such as painting, powder coating, wet coating, soldering, chemical treatment, e-coating (KTL), autoclave sterilisation, and PCB and electronics manufacturing expose labels to extremely high temperatures as well as aggressive cleaning agents and chemicals. In these cases, standard paper labels will not suffice. By choosing specialised heat resistant labels, you ensure reliable performance and durability throughout the required lifecycle.
Many of our heat‑resistant materials are developed for both complex industrial applications and long-term outdoor use, as they are weatherproof and UV-resistant. We recommend testing a label material beforehand to confirm it meets your requirements.
Which label materials are heat-resistant?
Polyester
Our standard polyester materials are suitable for applications where labels are exposed long term to temperatures of up to +150ºC. They also offer excellent resistance to oils and chemicals, with minimal shrinkage except under extreme heat conditions. This makes polyester a reliable choice for heat-resistant stickers used for labelling components, housings, electric motors, automotive parts, machinery and products such as televisions, screens and phones.
In addition to providing long-term readability, industrial identification often needs to offer protection against misuse and fraud. In such cases, we recommend our Checkerboard label material: a tamper-evident polyester material widely used in consumer electronics. It offers the same properties as other high temp labels, with the added benefit of leaving a visible checkerboard pattern on the surface upon removal. As a result, any attempt at fraud can be clearly detected.

- REACH/SVHC, RoHS, UL MH10170 (N) and MH16635 (N) compliant
M1701 Raised labels
Extreme permanent
- Temperature range: -40 to +90ºCÂ
- Adhesive strength: highÂ

Polyimide
If you operate in electronics manufacturing, for example in PCB production, we recommend using polyimide (Kapton®) label material.
It can withstand temperatures of up to +300ºC, while printed text and barcodes remain clearly legible. This makes it ideal for all stages of the PCB production process, where high-temperature labels are essential.
M1202 Polyimide
Extreme permanent
- Temperature range: -40 to +300ºCÂ
- Adhesive strength: highÂ
- Surface: smoothÂ
- REACH, RoHS, UL 969 compliantÂ
- MIL-STD-202G, Notice 12, Method 215KÂ
Polypropylene
Polypropylene materials offer heat resistance of up to approximately +80ºC, which limits their use in more demanding industrial applications.
This material is commonly used in the food industry. Compared with polyester, polypropylene is more flexible and adheres well to smooth and curved surfaces.
M1404 Polypropylene

- Temperature range: -20 to +80ºCÂ
- Adhesive strength: averageÂ
- Surface: curved, smoothÂ
- EU 1935/2004/EC, German Recommendation (BfR) XIV, FDA 175.105 compliantÂ
M1406 Polypropylene
Extreme permanent
- Temperature range: -55 to +90ºCÂ
- Adhesive strength: highÂ
- Surface: curved, smooth, roughÂ
- BS5609: 1986 Section 2 and Section 3 compliantÂ
M1471 Polypropylene
Non-adhesive tag
- Temperature range: -30 to +100ºCÂ
- Designed as a hang tag or non-adhesive insert label
- High chemical resistanceÂ
- Easy to attach using cable ties, rope or staplesÂ
A specialised heat-resistant label: Print & Protect labels
Many of our customers use blank polyester label materials to print type plates and asset tags in-house. If you prefer to design and print your own labels with long-term durability, PALLabels (Print and Laminate Labels), also known as Print and Protect labels, are a reliable solution. These high temperature labels are designed to maintain readability in demanding environments where conventional labels are insufficient.
