Abstract

resumo “composição, filme soprado, artigo e dispositivo recipiente” a presente invenção provê uma composição de mistura de polietileno apropriada para filme soprado, método para sua produção e filmes fabricados com a mesma. a composição de mistura de polietileno apropriada para filme soprado, de acordo com a presente invenção, compreende o produto de mistura sob fusão de (a) de 5 por cento em peso ou menos de um primeiro polietileno de baixa densidade (primeiro ldpe), tendo uma densidade na faixa de 0,915 a 0,935 g/cm3 e um índice de fusão (i2) na faixa de mais de 0,8 a um valor igual ou menor que 5g/10 minutos, e uma distribuição de peso molecular (mw/mn) na faixa de 6 a 10; (b) de 5 a 50 por cento em peso de um segundo polietileno de baixa densidade (segundo ldpe), com uma densidade na faixa de 0,915 a 0,935 g/cm3, e um índice de fusão (i2) na faixa de 0,1 a um valor igual ou menor que 5 g/10 minutos, e uma distribuição de peso molecular (mw/mn) na faixa de 6 a 10; contanto que o segundo ldpe tenha um índice de fusão (i2) que é diferente do índice de fusão (i2) do primeiro ldpe; de 44 por cento ou mais em peso de um polietileno heterogêneo linear de baixa densidade, tendo uma densidade na faixa de 0,917 a 0,950 g/cm3, e um índice de fusão (i2) na faixa de 0,1 a um valor igual ou menor que 5g/10 minutos; (d) opcionalmente um agente neutralizante à base de hidrotalcita; (d) opcionalmente um ou mais agentes nucleantes; e (f) opcionalmente um ou mais antioxidantes. quando dita composição de mistura de polietileno é formada em um filme via processo de filme soprado, a taxa de produtividade é melhorada em pelo menos 6 por cento, por exemplo, 7 por cento, em relação a uma composição de mistura de polietileno consistindo essencialmente de (a) um componente de polietileno heterogêneo linear de baixa densidade; e (b) um segundo componente de polietileno de baixa densidade similar. 1
