1. Emballage med en let kontrollerbar åbningsfunktion, hvilken emballage omfatter en beholder, der er baseret på en monolagsfilm, som er fremstillet af mindst en termoplastisk polymer, hvilken film eventuelt omfatter et forsegleligt lag (s), der er baseret på en varmeforseglelig, termoplastisk polymer, hvor åbningen af den nævnte beholder er forseglet med et dæksel, der er fremstillet af en transparent flerlagsfilm, som omfatter et forseglingslag (a), der er baseret på mindst én varmeforseglelig, termoplastisk, olefin homo- og/eller copolymer med en lagtykkelse på højst 12 pm og et til forseglingslaget (a) tilstødende lag (b), der er fremstillet af mindst én termoplastisk copolymer af ethylen og/eller propylen og af mindst en α-olefin, der har mindst fire carbonatomer, hvilket nævnte lag (b) er baseret på en termoplastisk polymer, der er forskellig fra de termoplastiske polymerer af forseglingslaget (a), og eventuelt omfatter andre lag, hvor det eller de eventuelle tilstedeværende, forseglelige lag er baseret på den eller de samme polymerer som det forseglelige lag (a) og de termoplastiske olefin-homo- og/eller copolymerer, hvorfra monolagsfilmen af beholderen er fremstillet, er de samme som dem, hvorfra det forseglelige lag (a) er fremstillet, eller alternativt åbningen af beholderen er forseglet med et dæksel, der er fremstillet af en transparent flerlagsfilm, som omfatter et forsegleligt lag (a), der er baseret på mindst én varmeforseglelig, termoplastisk, amorf homo- eller copolyester med en lagtykkelse på højst 12 pm og, tilstødende til det forseglelige lag (a), et lag (b), der er fremstillet af mindst en ethylen-copoly-mer, som er valgt fra gruppen, der omfatter ethylen-vinylacetat-copolymerer, ethylen-Ci-4-alkyl(meth)acrylat-copolymerer og ethylen-(meth)acrylsyre-copoly-merer, hvor laget (b) er baseret på en termoplastisk polymer, der er forskellig fra de termoplastiske polymerer af forseglingslaget (a), og eventuelt omfatter andre lag, hvor det eventuelt tilstedeværende forseglelige lag (s) er baseret på de samme polymerer som det forseglelige lag (a) og monolagsfilmen af beholderen er fremstillet af en termoplastisk homo- og/eller copolyester, hvor vedhæftningen mellem det forseglelige lag (a) og laget (b) i hvert tilfælde er med mindst 30 % mindre end forseglingsstyrken mellem beholderen og dækslet, hvilket bevirker at bindingen mellem det forseglelige lag (a) og laget (b) i flerlagsfilmen er tilstrækkelig aftrækkeligt til, at der under den første åbning af emballagen i området for forseglingssømmen kun er en sektion af det forseglelige lag (a) i bredden, der forbliver på beholderen, og der ikke finder yderligere delaminering sted mellem lagene (a) og (b).

Emballage ifølge et af kravene 1 til 7, kendetegnet ved, at flerlagsfilmen omfatter et lag (c) som barrierelag, fortrinsvis som et gasbarrierelag, der eventuelt i hvert tilfælde er bundet til et lag (h) af polyamid eller eventuelt er bundet i hvert tilfælde ved hjælp af et vedhæftningsfremmende lag (d) til det tilstødende lag.
9. Emballage ifølge krav 8, kendetegnet ved, at barrierelaget (c) er baseret på mindst én termoplastisk polymer, der er valgt fra gruppen, som omfatter ethylen-vinylalkohol-copolymerer, mindst delvist hydrolyserede polyvinylacetater, polyvi-nylidenchlorid, vinlyiden-copolymerer eller en blanding af mindst to af de nævnte polymerer, fortrinsvis på mindst en ethylen-vinylalkohol-copolymer.
