2. Emballage (10) ifølge krav 1, hvor mindst et segment af flappens endestykke (28) er adskilt fra resten af filmen (100) af en gennemskæring (20).
3. Emballage (10) ifølge krav 2, hvor flappen kan adskilles fra filmen (100) langs et par af ridselinjer (22), idet hvert par af ridselinjer (22) krydser gennemskæringen (20), og hvert par af ridselinjer (22) har segmenter, der divergerer fra hinanden.
4. Emballage (10) ifølge et hvilket som helst af de foregående krav, hvor flappens endestykke (28) indbefatter en genlukningszone på en side af filmen (100), der vender ind mod det indre og strækker sig væk fra forseglingszonen, hvilken genlukningszone har et klæbemiddel (18), der er konfigureret til at blive selektivt klæbet til klæbemidlet (18) i forseglingszonen på et hvilket som helst af en flerhed af forskellige steder i genlukningsklæbemiddelzonen med henblik på generelt at lukke adgangsåbningen (24) igen ved hjælp af flappen.
5. Emballage (10) ifølge krav 4, hvor klæbemidlet (18) i genlukningszonen har en større affinitet for klæbning til klæbemidlet (18) i forseglingszonen end til en fødevare (12), der er beliggende i det indre af emballagen (10).
6. Emballage (10) ifølge krav 2 eller et hvilket som helst af kravene 3-5 som afhængigt af krav 2, hvor finneforseglingen (14) indbefatter en distal flange af mindst et af parrene af kantstykker (104), der strækker sig forbi forseglingszonen og modsat det indre, og flappens endestykke (28) strækker sig forbi forseglingszonen og ind i den distale flange, et segment af flappens endestykke (28), der er beliggende i den distale flange, er adskilt fra resten af filmen (100) af gennemskæringen (20).
7. Emballage (10) ifølge krav 6, hvor et startområde af flappens endestykke (28) er beliggende mellem gennemskæringen (20) og en ridselinje (22), der er nabo til og generelt på linje med gennemskæringen (20), hvilket startområde rager ud fra et naboområde til flappens endestykke (28).
8. Emballage (10) ifølge et hvilket som helst af de foregående krav, hvor flappen indbefatter en genlukningszone på en side af filmen (100), der vender ind mod det indre og strækker sig væk fra forseglingszonen, hvilken genlukningszone har et klæbemiddel (18), der er konfigureret til at blive selektivt klæbet til klæbemidlet (18) i forseglingszonen på et hvilket som helst af en flerhed af forskellige steder i genlukningsklæbemiddelzonen med henblik på generelt at lukke adgangsåbningen (24) igen ved hjælp af flappen, idet klæbemidlet (18) i genlukningszonen har en højere affinitet for klæbning til klæbemidlet (18) i forseglingszonen end til en fødevare (12), der er beliggende i det indre af emballagen (10).
