Abstract

Um filme de múltiplas camadas fundido inclui uma camada de aderência, uma camada de liberação e pelo menos uma camada de núcleo disposta entre e que entra em contato com a camada de aderência e a camada de liberação. A camada de aderência inclui um polietileno de densidade ultrabaixa (ULDPE), um interpolímero de propileno ou suas misturas. A camada de liberação inclui um primeiro polietileno linear de baixa densidade (primeiro LLDPE) com uma densidade de 0,915 a 0,938 g/cm³ e um índice de fusão de 0,5 g/10 min a 10 g/10 min. Cada uma das camadas do núcleo inclui um segundo polietileno de baixa densidade linear (segundo LLDPE) com uma densidade de 0,905 a 0,930 g/cm3 e um índice de fusão entre 0,5 g/10 min e 10 g/10 min. O filme de múltiplas camadas fundido inclui de 3% em peso a 7% em peso, com base na quantidade total de polímeros presentes no filme de múltiplas camadas fundido, do polietileno de baixa densidade (LDPE).
