Window patching is an attractive form of presenting goods through the cut out opening in the folding box, which is sealed over with transparent film. We use PET, PE and PVC film for sealing over the cut-out windows, which can also be applied over the corner of the packaging. 

A special category of window patching is the production of folding boxes for sanitary towels, for which we replaced PE foil with paper. The sealing over of windows with paper ensures the sanitary protection of towels during gradual consumption and enables the full recycling of the packaging along with the window.
