Cartonboard made by Klabin, Sao Paulo, Brazil, is being used in multi-pack packaging for three beer products of Petropolis Brewery, Brazil—Crystal Premium long-neck bottles, the box of eight cans of Itaipava Fest, and the bottles and cans of Itaipava Premium. To assure the quality of multi-pack packaging for the beer, Graphic Packaging International (GPI), Marietta, Ga., USA, reports that it used Klabin's KlaMulti cartonboard designed for high tear and moisture resistance, essential properties to wrap and protect beer, yoghurts, soft drinks, etc.
Made from a mixture of short (eucalyptus) and long (pine) fibers, in the case of the Petropolis Brewery's packages, Klabin cartonboard is treated with metalized film, giving it a shiny, silvery appearance and making it visually more attractive at the point of sales. On the inside, the board has special sizing that ensures high mechanical strength, even when stored under severe moisture conditions. Its fiber composition, together with a triple layer of coating, provides an enhanced surface for direct printing, as well as al base for laminating special films.
