High Temperature Heat Proof Labels and Tags


High Temperature Heat Proof Labels and Tags

Heat resistant or high temperature labels and tags are labels (or tags) that can be used at temperatures over 150 degrees C (and in some cases, up to 1,650C). They come in different colours and finishes (gloss, silver metallic etc.).  All can be pre-printed with a logo and text and can be overprinted with variable information such as serial numbers, batch codes or barcodes.

Not All High Temperature Labels are the Same

Applying Heatproof labels
Some labels need special applicators

High temperature labels (sometimes known as heat resistant or heatproof stickers) have different characteristics and won’t all perform the same way.  For example, some label materials can withstand prolonged high temperatures whilst others will only work at high temperatures for short periods.  Not all labels can be applied at high temperatures and thought needs to be given to how much rubbing or abrasion is likely to be encountered.

Heat resistant labels may also need to survive multiple reheating cycles.  Other things to bear in mind are the method of applying the labels to the material.  Thermal transfer ribbons (inks) need to be carefully matched to the label and have to be tested.  For expert advice on what labels tags and ribbons work best, and for a sample thermal transfer ribbon, contact us here.  Please note we are only able to work with UK customers.

How much would I pay for High Temperature Labels?

Heat resistant labels are specialist products and in the case of labels needing to survive over 350 Deg C, tend to be expensive compared to standard labels.  Bear in mind the hidden costs of mis-identifying high value items, which can run into thousands of pounds, expect to pay around £1 per label or tag for labels to survive in the very high temperature ranges.

Luckily, with more than 20 years experience using label and tag design software, we’re able to help you optimise the design of your labels, minimise wasted label space and ultimately reduce the cost of your high temperature labels and tags.

Keen to Test Some Labels?

Testing tags at 1000 Deg C

In order to help you make the right decision and choose the best value labels for your project, we’re able to provide UK-based companies with samples for testing.  Fill in the sample request form (click the button at the top right of the page) or contact us with as much information (including photos) about your project as you can.  If your project is commercially sensitive, we’re happy to sign an NDA.

We provide a sample service for high temperature labels so you can test them on your products and under your conditions.  Fill in the sample request form (at the top right of this page) – give us as much detail as you can (what you’ll be labelling, what temperature the label will need to survive and most importantly – how many labels you think you’ll need).  We can then send you some suitable sample material (if you are located in the UK).

High Temperature Label Products

MaterialTemperature rangeConsiderations
PET and Polyester labels-40 to 150CThese labels can be applied by hand and printed with a standard thermal transfer printer using resin ribbons.
Polyetherimide-40 to 270CThese labels can be applied by hand.  They are designed for shorter periods up to 200C (60 minutes) but provide excellent results up to 150C.  Can be printed with a standard thermal transfer printer using resin ribbons.
Polyimide (Kapton(r))-40 to 350CThese labels can be applied by hand.  These are specified to resist temperatures up to 240C for up to 80 minutes and as much as 300C for 5 minutes.  The labels can be printed with a standard thermal transfer printer using resin ribbons.
HP-T400 to 450CThe HP-T40 material is in Tag form and is not adhesive.  They can be nailed, bolted, spot welded or clipped into place to identify items.  These tags use a special thermal ink ribbon for printing.  They also come on continuous rolls and need to be printed and cut using your printers cutter.  Most printers don’t come with cutters.  Contact us for advice on the most reliable printers to cut you HP-T40 material.
CBR-CX2T0 to 1250CThese labels are specially made to order.  They can be variable printed on site using a special thermal printer ribbon.  They need to be applied using a special label applicator.  These adhesive labels use a special thermal ink ribbon for printing.
Ceramic0 to 1650CThese labels are made from a special ceramic material that can be over printed with special thermal ink ribbon and a standard thermal transfer printer (such as a Zebra, Datamax O’neil or Godex printer).  They are all made to order and have a lead time of 3 or 4 weeks.  These ceramic heat proof labels come in three forms – full ceramic tags, ceramic labels applied to steel base-plates and ceramic labels that can be applied to different materials – such as glass and metal.

Availability of Heat Resistant labels

Many of our heat resistant labels, when combined with an approved thermal ink ribbon are automotive and UL approved.

Please remember, high temperature and heatproof labels are specialist labels and are not widely available.   There are a limited number of label dimensions available from stock.  Many of the ultra high temperature product has a four week lead time and comes in limited roll widths.

Please contact us to see what is available from stock.

Heat Resistant and High Temperature Labels

Additionally we can make to order and over print for you,  but please bear in mind, whilst we are able to supply smaller quantities than most of our competitors, these high temperature materials are high cost and generally have minimum order quantities of at least 1000 labels. We would be very pleased to discuss your project requirements so please contact us to find out more.

High Temperature and Heat Resistant Labels – Questions to Consider:

  • Why are the labels or tags being applied? (traceability, stock control or tracking)
  • What is the maximum temperature your label needs to survive?  For how long?
  • At what temperature will your label be applied?
  • Does the label or tag need to be heated and cooled many times?
  • What material will the label be attached to?
  • Will it be rubbed?
  • Will any chemicals be applied to the label?
  • What needs to be printed on the label?
  • How will the labels be applied to the item?

If you need high temperature labels, speak to one of our labelling experts today call 01359 271 111. Alternatively, if you are UK based, please request a sample pack by filling in the sample request form or email us from our contact us page.  Not all the label materials are available as samples.

Features of heat resistant labels

High Durability

The aggressive pressure sensitive adhesives are specifically formulated to remain firmly affixed to PCBs and components through wave solder, reflow and high pressure washes. 

High Resolution

Polyonics high-gloss materials are designed specifically for printing high resolution 600 dpi thermal transfer printing. 

Flame Retardant

The labels are either recognized or tested to the UL94 VTM0 standard, tested to the FAR 25.853 and BSS 7238/7239 aerospace flammability, smoke and toxicity standards and/or tested to the FMVSS 302 automotive burn test.


These durable label materials provide increased ink adhesion without requiring reflow to set the ink.
