Abstract

Oppfinnelsen vedrører en fremgangsmåte for fremstilling av orientert polyolefin hvori betingelser for strekking eller orientering er definert for å maksime- re den uhindrede (fri) krymperespons for filmen. Oppfinnelsen vedrører også en krympefilmstruktur såvel som en krympefilmstruktur fremstilt ved hjelp av den nye fremgangsmåte hvori i hvert tilfelle krympefilmen som krympekontroll-lag omfatter minst en homogent forgrenet etylen-interpolymer med en polymerdensitet under 0,91 g/cm3. Fremgangsmåten har kommersielle og utviklingsmessige fordeler og filmstrukturen kan utnyttes ved slike anvendelser som industriell kollatering av pa- pfrvarer og barriereemballering av næringsmidler.
