Tyre Labelling
Tyre labels function as carriers of important information about a tyre including the brand, type, dimensions and product bar code.
The adhesive for tyre labelling should perform well during the following stages:
- conversion of the laminate into labels
- dispensing of the label from the liner onto the tyre
- distribution and storage on rough tyre profiles
- removal from the tyre so that the label face pulls away cleanly
Barrier properties are essential
For extremely rough tyre profiles like those on winter tyres, UPM Raflatac recommends Raflatyre, a paper face with an aluminium barrier on the underside. The aluminium layer prevents components from both the tyre and adhesive from migrating through to the face. A second positive side to the aluminium layer is its ‘memory folding’ property, which helps the label conform and stay fixed to the tyre profile.
Naturally there are environmental concerns over the use of aluminium, and for this reason some countries are moving towards the use of filmic face materials for tyre labels.
For general tyre labelling, Syntyre, a PP based face material, is advisable in combination with UPM Raflatac’s RH/T high coat-weight adhesive.
Syntyre TC 90 is recommended for tyre labels dispensed automatically.
Choosing the right printing method
The most common printing methods for these labels are UV flexography for colourful brand marking and thermal transfer for printing variable information.
