Abstract

En polymer film fremstilt ved å blande sammen pelleter av stivelse og av PVA, og deretter ekstrudere blandingen termoplastisk. Blandingen bør inneholde minst 10% og foretrukket minst 25% (uttrykt i vekt) av hver polymer, og ekstrudering danner en homogen film som fremstår som uniform. Den kan være så tynn som 20 µm. Den resulterende film kan lett bionedbrytes, den er vannoppløselig eller vanndispergerbar og har gode fysiske egenskaper. Denne samme ekstruderingsprosess av en pelletblanding, etterfulgt av sprøytestøping, kan anvendes for å danne andre gjenstander.
