Two-Part Protection Labels

Boreholes on components have to be protected from contamination. Therefore, a self-adhesive film is applied over the entire surface.  During the subsequent assembly process, the label can be removed in segments without leaving any residue.

Material - Two-layer construction:

A. Base label: plain red (RAL3001) printed polypropylene
>> Material 4106 1501 - printed Polypropylene 60 µm  
>> this label has two segments

B. Cover label: printed in blue and black
>> Material 4006 1500 Polypropylen 60 µm
>> "bridges"  the two segments together
>> is only partially laminated


Features and Benefit:

  • Removable without leaving any residue on the substrate, even after extreme conditions (temperature and humidity)
    >> saves time and avoids complex cleaning process
  • Partial adhesive zone coating (“deadening”) allows easy handling of the label
  • Special die-cut geometry

Application area:
The label is used to cover boreholes on a metal block. It consists of two base label segments, which are stabilized by a second laminated, transparent “bridge” film to ensure stable automatic label application. Upon removal of the first label segment the transparent film is completely removed – only the second segment of the base label remains on the component part. This will be removed in a second process step.
