"Although Harry Järund’s machine was not perfect, it was still a prototype. Ruben seemed relieved. But still, enormous problems remained. There was no material available to coat the paper to make it leak-proof. Wax, which was the usual sealing agent, could not be used as it would break in the folds. It also could not withstand heat sealing; it would melt. Overall, there was no known coating material that would withstand heat sealing without altering the taste of the milk. And if they did succeed in finding an alternative that could be used, how would it be applied to the paper and were there coating machines available? Before the war, Imperial Chemical Industries (ICI) in the UK had developed a low molecular weight polyethylene plastic. It was not suitable for coating a tetrahedron, but Stig Sunner believed that a high molecular weight polyethylene would work well for tetra packaging. Erik Torudd, who was in charge of the commercial part of the material issue, contacted ICI to inquire if they could possibly develop such a plastic. If the trials were successful, ICI would become the sole supplier of polyethylene for milk packaging. This was a very tempting bait. Torudd received an affirmative answer, but with the reservation that it would take time."

"“If I think about what they have meant to us - Erik Wallenberg, through his Tetra invention, Gunnar Brime through 27 years of activity in ÅR, Torsten Jeppsson through his devoted, tremendously hard work over many years, Harry Järund through his inventing activities, Stig Sunner through his scientific advising, Erik Torudd for his commitment to Tetra Pak from the very first minute, Göte Engfors through his 20-year, significantly underpaid directorship in our various companies, and Carl Borgström’s exceptionally important advising for our operations - then the price you mention, as far as I can judge, is really not reasonable,” he continued. But Holger never had the chance to carry out his plan to help the remaining small shareholders."
