9. VSP-pakning, som omfatter en første bane, der består af flerlagsfilmen ifølge et hvilket som helst af kravene 1 til 8, og en anden bane, der omfatter et ydre forseglingslag, hvilket forseglingslag omfatter en polymer valgt fra gruppen bestående af neutraliserede ethylen/(meth)acrylsyre-copolymerer, LDPE, ethylen/alfa-olefin-copolymerer og ethylen/vinylacetat-copolymerer, hvor den første og den anden banes forseglingslag er forseglet til hinanden.
10. Pakning ifølge krav 9, hvor den anden banes forseglingslag består af LDPE.
11. Pakning ifølge krav 9, hvor den anden banes forseglingslag består af en neutraliseret ethylen/(meth)acrylsyre-copolymer.
