Heat-sealable multilayer film of reclosable packages and use thereof

Heat-sealable multilayer film (1) comprising an outer layer (5) and a support layer (6) which has a heat-sealable layer (8) on its side facing the packed material (3). A self-adhesive layer (7) formed from pressure-sensitive adhesive is provided between the support layer (6) and outer layer (5) and in that support layer (6) has weakening lines (4, 4') and stamped portions (11), which define an opening (9, 13) for the removal of packing material (3). Next it is described use of a heat-sealable multilayer film for sealing food containers, such as yoghurt pots (3) which are opened by means of an opening aid, preferably a gripping tab (2), in such a way that during opening, the opening (9,13) for removing the containers contents is formed inside the support layer (6) according to the weakening lines (4, 4') and stamped portions (11), which opening (9, 13) can be sealed again by the pressure-sensitive adhesive layer (7). Vrstvená fólia (1) pozostáva z vonkajšej vrstvy (5) a nosnej vrstvy (6), ktorá je na svojej strane privrátenej k tégliku (3) vybavená teplom pečatiteľnou vrstvou (8). Medzi nosnou vrstvou (6) a vonkajšou vrstvou (5) je usporiadaná na tlak citlivá lepiaca vrstva (7) a v nosnej vrstve (6) sú vytvorené línie (4, 4') zoslabenia a prelisy (11), ktoré vymedzujú otvor (9, 13) na odoberanie obsahu téglika (3). Ďalej je opísané použitie tejto teplom pečatiteľnej vrstvenej fólie na uzatváranie nádob s potravinami, ako sú tégliky (3) s jogurtom, ktoré sapomocou otváracej pomôcky, výhodne úchopného jazýčka (2), otvárajú tak, že pri otváraní sa v nosnejvrstve (6) zásluhou línií (4, 4') zoslabenia a prelisov (11) vytvára otvor (9, 13) na odoberanie obsahu téglika (3), ktorý môže byť uzatvorený na tlak citlivou lepiacou vrstvou (7).
