Abstract
"POLìMERO PARA MOLDAGEM POR INJEçãO". A invenção refere-se à utilização de um LLDPE produzido utilizando um catalisador de sítio único, por exemplo, um LLDPE produzido utilizando um metaloceno (m-LLDPE), na moldagem por injeção de material de embalagem de alimento, especialmente fechamentos para recipientes de alimentos. Foi verificado que tais materiais apresentam baixos níveis de migração, tipicamente de menos do que 40 mg/dm^ 2^ por exemplo, menos do que 5 mg/dm^ 2^, e são particularmente adequados para a utilização na embalagem de alimentos tendo um elevado teor de gordura.
