Abstract

Det er beskrevet forseglbare polypropylenfoller med forbedret vanndampsperrevirkning, med følgende sjiktoppbygning: A B C B A a) hvorved C er baslssjiktet av høyisotaktisk polypro- pylen som har en isotaktisitet større enn 94 % og en hydrokarbonharplks som oppviser en molmasse Inntil ca. 2000 g/mol og har et mykningspunkt over 130*C, b) og B er to hydrokarbonharpiksfrie mantelsjikt av høy isotaktisk polypropylen med en isotaktisitet >94 %, hvorved forholdet mellom tykkelsen av et mantel- sjiktet og tykkelsen av basissjiktet ligger mellom 0,01 og 0,1. c) hvorved A er to dekksjlkt av en varmeforseglbar polyolefin-, homo-, ko- eller terpolymer, hvorved | disse dekksjiktene inneholder minst ett anti- ! blokkeringsmiddel, et glidemiddel og et antl- i statikum.
