Abstract
Foreliggende oppfinnelse omhandler en filmblanding med egenskaper som forsegling som omfatter minst to bestanddelsmaterialer av etenpolymer. Ett formål med oppfinnelsen omhandler en flersjiktssammensetning som har balanserte egenskaper som forsegling.... og omfatter et tetningssjikt og et polypropensjikt, hvori tetningssjiktet omfatter og er fremstilt av en polymerblanding, som har særskilte molekylvektegenskaper, og en etenpolymer nummer to. En foretrukket utførelsesform i foreliggende oppfinnelse omhandler en polyolefinfilm med medium tetthet og en blanding karakterisert ved at den har en utmerket likevekt mellom en lav initieringstemperatur ved forsegling og en forbedret filmmodul. Filmen og blandingen består av og er fremstilt av minst en homogent forgrenet etenpolymer med lavere tetthet og minst en heterogent eller homogent forgrenet etenpolymer med høyere tetthet. Oppfinnelsen er i særdeleshet nyttig til de anvendelser som krever raske forseglingstider og god målbestandighet ved emballering, så som, for eksempel, "cook-in" (kok deri) pakking, varmfyll pakking, poser til flytbart materiale, pakking ved kompresjonsfylling, krympefilmpakking og pakking med barrierekrympefilm, samt til biaksialorienterte filmsammensetninger av polypropen (BOPP).
