Abstract

Oppfinnelsen vedrorer en fremgangsmåte ved fremstilling av en flersjikts-, fortrinnsvis tosjikts-kompositt av en skummet polystyrenfolie med en koekstrudert uskummet folie, spesielt for videre bearbeidelse til etiketter eller formlegemer, under utnyttelse av foliens kryrope- evne, hvorved en polystyrenharpiksmasse sammen med nitrogen som drivmiddel og en poredanner ekstruderes ut av en ekstruders dyse, og den ekstruderte masse opp- blåses for avkjøling under mykningspunktet. For å oppnå en materialsparende og minst mulig cmtålelig produksjon av skummede polystyrenfolier som også skal være mest mulig aldringsmotstandsdyktige og lette og trykke på, foreslår oppfinnelsen at det som drivstoff anvendes pr. kg skummet folie utelukkende nitrogen i en mengde av 1/30 til 1/50 (målt i ni) av folieflatevekten (målt i g/m2), sammen med en pulverblanding av natriumbikarbo- nat og sitronsyre, og foliens stivhet/ovberflatebeskaf- fenhet reguleres ved oppblåsningsforholdet.
