Abstract

Patente de Invenção:<B>"PELìCULAS DE POLìMERO E PROCESSO PARA A PRODUçãO DAS MESMAS"<D>. A presente invenção refere-se a uma composição de polietileno particularmente adequada para sopragem de película. A invenção também trata de um processo para a sua produção. A composição compreende uma porção com baixo peso molecular que tem uma densidade de mais de 960 kg/m^ 3^ e uma porção com alto peso molecular. A composição de polietileno tem uma densidade de cerca de 925 a 940 kg/m^ 3^ e uma taxa de fluxo em fusão na faixa de MFR~ 21~ de 5 a 40 g/10 min. Uma película de polietileno soprado com a composição de polietileno exibe um limite de resistência à tração no escoamento na direção transversal de pelo menos 15 Mpa, um módulo secante a 1% na direção da máquina de pelo menos 30 Mpa e na direção tranversal de pelo menos 400 Mpa e uma queda de gota de pelo menos 5 g/Ám.
