Philip Morris created for its Benson & Hedges 100’s DeLuxe Ultra Lights Spotlight Report in a flip-top box was certainly no exception. ® Packaging Machinery Packaging such boxes normally requires special attention to avoid scratches on the film and scuffs on the blank, but the unique construction of the DeLuxe Lights pack blank compounded the problem. In addition High-tech coatings enhance the efficiency to the highly reflective surface and the embossed crest, the clear and performance of packaging equipment polypropylene film had to be free of scratch marks.
