  PEN is an industrial polyester plastic which has become interesting for the
physics community as a new type of plastic scintillator. PEN scintillates in
the blue regime, which is ideal for most photosensor devices. In addition, PEN
has excellent mechanical properties and very good radiopurity has been
achieved. Thus, it is an ideal candidate for active structural components in
low-background experiments. One possible application are holders for germanium
detectors operating in cryogenic liquids (LAr, LN2). Such structures can help
to reject surface and external backgrounds, boosting the sensitivity of
experiments. In this contribution, the R\&D on PEN is outlined and an
evaluation of the first production of PEN structures for the LEGEND-200
experiment is reported.
