Window-patching is inserting a (transparent) foil into packaging. This ensures that the product does not contact the carton directly and that the packed product can be seen from the outside. A suitable solution is available for every product. The application of, for example, a mirror or microwave foil is also possible.

The pick & place technology makes it possible to glue diecutted and precreased windows. This allows various types of folding boxes with 3D windows to be realised.
