The company said that its new combiCap closure for the carton weighed 1.9g, 60% less than the first ever SIG Combibloc screwcap, and a SIG Combibloc spokeswoman said that it was an "extremely lightweight solution".SIG Combibloc said it applied the screw cap on an over-coated hole that was punched into the raw paperboard before it was laminated.
