Abstract

Bi- eller multilags polymerfilm omfattende områder av kontrollert fonn hvor i det minste to tilstøtende lag er uforseglet, hvor områdene som er visuelt distinkte fra bakgrunnen som består av andre deler av filmen, hvor fortrinnsvis alle lagene er forseglet til hverandre, og en prosess for å fremstille disse.Bi- or multilayer polymer films comprising areas of controlled form where at least two adjacent layers are unsealed, the regions visually distinct from the background consisting of other portions of the film, preferably all layers being sealed to each other, and a process for manufacture these.
