Abstract
"PELìCULA DE POLIETILENO Dé ALTADENSIDADE, MULTILAMINAR, COM ALTA ORIENTAçãOBIAXIAL". A presente invenção refere-se a uma película depolietileno de alta densidade multilaminar (HDPE) apresentandoalta orientação biaxial. A película inclui um substrato de HDPE,pelo menos uma camada externa de copolímero de propileno, epelo menos uma camada de um material promotor de adesãoposicionado entre a camada externa e o substrato de HDPE, paraeficientemente mediar a adesão entre eles. O promotor de adesãoé de preferência um material de adesão tendo uma densidademenor do que a do material base de HDPE. Materiais de promotorde adesão preferidos incluem polietileno de densidade muito baixa(VLDPE), polietileno de densidade baixa de elevada pressão(HP-LDPE), polietileno de baixa densidade linear (LLDPE), epolietileno de média densidade (MDPE). A película é altamenteorientada biaxialmente, sendo estirada na direção da máquina a umgrau de 5:1 a 8:1, preferivelmente de 6:1 a 7:1, e estirado, nadireção transversal, multilaminar a um grau de 6:1 a 15:1,preferivelmente de 9:1 a 13:1.
