Application:
Multilayer paint protection labels for powder coatings

The user

deploy powder coatings for finishing their metal parts out of steel, aluminium or other electrically-conductive materials.

Initial situation

Particularly in the automotive industry, parts and components have to be marked before pre-treatment and powder coating to enable reliable traceability. A barcode label was needed for use at an automotive manufacturer that would clearly identify the vehicle chassis during manufacturing and the vehicle throughout its service life.

A label was required that would afford permanent surface protection and thus allow for permanent identification. Moreover, three additional transparent, removable foil layers were needed for each of the three coating processes; the respective upper layer then being peeled off after each drying phase to allow the barcode to be scanned.

Solution from ELTEX

A heat-resistant ELTEX TOP CODE foil is imprinted with the desired barcode and plain text and is subsequently laminated with a system of three different, removable, transparent foils. It is then die-cut onto the desired label format.

The adhesive strength of the individual removable foils correspond with each other to such an extent that only the upper layer can be easily removed after each coating process in a practical manner. An additional, firmly-attached laminate foil protects the barcode permanently against aggressive elements.
