Definitions
- the invention relates to a laser transfer film for the permanent labeling of components from a carrier layer, an adhesive layer with a pigmented boundary layer being present on the lower side of the carrier layer.
- Technical labels are used to identify components on vehicles, machines, electrical and electronic devices, for example as type plates, as control labels for process sequences and as warranty and test labels.
- Labeling using laser labels and printed or lacquered metal signs is becoming increasingly important, especially in the automotive industry, especially for high-quality markings.
- information and notes such as tire pressure or type of fuel are placed on various components of the automobile for the later user.
- Important production data can also be transported via a laser label in the upstream production stages.
- the label can be labeled with a barcode.
- a suitable reading device enables an assembly team to read information about the model, color and special equipment directly on the production line using the barcode.
- Powerful controllable lasers for burning markings such as writing, coding and the like are common.
- the following requirements are placed on the material to be labeled or the material used for labeling:
- High temperature resistance should be given, for example up to over 200 ° C.
- labels When using flat, sharp blades, labels can be completely removed from the substrate.
- the bond between the adhesive and the substrate shows weaknesses, particularly on plastic substrates such as polyethylene or polypropylene.
- plastic substrates such as polyethylene or polypropylene.
- a special blade tool can be inserted under the label at a flat angle. Careful cutting movements make it possible to lift an edge, creating a so-called handle. In this way you create a point of attack that simplifies detachment.
- the object of the invention is to provide a laser transfer film which enables the rapid and precise labeling of any component, which meets the stated requirement of improved security against forgery, which cannot be removed without being destroyed even with the aid of a cutting tool, in particular high contrast, has high resolution, high temperature resistance and easy application.

- the base body for the intermediate carrier can be selected from all common materials for such purposes. Woven webbing made of glass fiber, polyester, polyamide or Nomex®, a fiber material from DuPont, is particularly advantageous. But also rubber blankets, plastic straps and the like have proven to be cheap. If fabric tapes are selected, it is favorable to use tapes which are already provided with an essentially unstructured plastic surface coating. This latter coating promotes the adhesion and uniformity of the actual surface coating on the base body.
