Retortable paperboard packaging material for foodstuff
The Marcus Wallenberg Prize for 2005 of 2 million Swedish Crowns will be awarded to Mr. Tom Kjelgaard, Ms. Katarina Magnusson and Mr. Ulf Ringdahl for their path breaking research leading to a retortable paperboard packaging material for foodstuff.Specifically, they developed a packaging material structure that is sufficiently flexible during forming and filling to avoid cracking of the critical barrier layer; it retains print quality and maintains an effective gas and vapour barrier throughout the retorting process. This development enables the production of a package that is both
