The following is from a company (Combibloc) who is using the laser developed by Laser Machining to produce aseptic packs for tomato-based products. TCBG is also using the laser from LM. From the inside-out, the nearly 14-mil carton includes a low-density polyethylene sealant layer/alcohol-based ionomer tie layer/aluminum foil for oxygen barrier/ LDPE/paperboard/LDPE. Combibloc gravure-prints the outer LDPE layer in six colors. Carton blanks are then scored by Combibloc on an infrared LaserGraver® laser cutting system from Laser Machining (Somerset, WI). According to Combibloc, the laser provides a critical advantage compared to mechanical cutting tools because it's able to score completely through the paperboard layer down to the foil, without penetrating the foil and compromising the carton's oxygen barrier. "The foil reflects the infrared laser beam like a mirror," claims Combibloc chairman Warren Tyler. Somewhere in that TCBG pouch there's got to be some foil to reflect that laser. Just hope it doesn't raise hell with a magnetron. Steve
