Abstract

"PROCESSO PARA ABAIXAR A TEMPERATURA DE TERMOSSELAGEM DE UM TERMOPLáSTICO, PROCESSO PARA A PREPARAçãO DE UM ARTIGO E ARTIGO". A presente invenção se refere a poliolefinas, preferencialmente o polietileno, que têm uma densidade de aproximadamente 0,86 a aproximadamente 0,93 g/ml, e dotadas de ramificações metila e pelo menos ramificações de dois outros comprimentos diferentes de seis átomos de carbono ou menos, formam vedações térmicas a temperaturas excepcionalmente baixas, permitindo desse modo que boas vedações sejam formadas rapidamente. Isso é vantajoso quando da termosselagem dessas poliolefinas, por exemplo, na forma de filmes de uma só camada ou de múltiplas camadas.
