One of the most important properties of laser-markable labels is lasting durability, because they stick to their intended location for the entire life of a car or component. And they do this regardless of heat, cold and many other harsh conditions over a sometimes very long car life.
This durability is why these labels enable a whole range of extremely important functions. For one thing, they are used to ensure the traceability of a car. This is because each laser label is one of a kind and contains a unique vehicle identification number, which is particularly important if the vehicle is stolen. Besides the vehicle number, the label also contains information that further identifies the vehicle and is relevant for repair, sales and to proof the vehicle's origin. And in addition – this is where very many superpowers are required – they offer protection against tampering. It is impossible to remove a laser label without damage.
These days, such tamper-proof certification in cars is even mandatory. That is why many countries have different standards with accordingly high requirements.
