Windowing is the process of applying a clear film or window to a carton for the purposes of viewing the contents inside the carton. This window is applied in a high speed process where the carton is passed through and a pattern adhesive is applied around the area where the window is to be fixed. Next the clear window film is set onto the adhesive and passed under a UV light source to cure the adhesive and permanently bond the window in place. This windowing process can be done with a Solvent, Water or UV adhesive. All of these processes can be converted to UV LED for significant production and application improvements.
Advantages over Mercury UV:
- Increased run speed
- Increased Bond Strength to Destruct (Fiber Tear)
- Low Heat – No Board Warping
- Improved Safety (No Carton Jam Fires)
