Abstract

Det er beskrevet orienterte, forseglbare polypropylen- folier med forbedret vanndampsperrevirkning ved betydelig reduserte friksjonskoeffislenter for forpakningsformål, kjennetegnet ved at de er frie for polydimetylsiloksan og oppviser følgende sjiktopp- bygning: A B C B A a) hvorved C er kjernesjlktet, bestående av polypro- pylen og en hydrokarbonharplks som oppviser en molmasse Inntil ca. 2000 g/mol og et mykningspunkt over 130'C, og 0,05 til 0,5 vekt-£ erukasyreamid, b) og B er to hydrokarbonharpiksfrie mantelsjikt av høy isotaktisk polypropylen med en isotaktisitet >94 %, hvorved forholdet mellom tykkelsen og mantelsjlktet og tykkelsen av baslssjiktet ligger mellom 0,01 og 0,1, c) og A er to dekksjikt av en varmeforseglbar poly- olefin-, ko- eller terpolymer, hvorved disse dekksjiktene inneholder minst ett antiblokkerings- middel, et antistatikum og som glidemiddel 0,05 til 0,5 vekt-% erukasyreamid.
