Title (EN) POLYOLEFIN FILM WITH IMPROVED TOUGHNESS
(FR) FILM DE POLYOLÉFINE À TÉNACITÉ AMÉLIORÉE
Abstract:
(EN) A film formed from a polyethylene copolymer using a reduced chromium oxide catalyst, ethylene monomers and a co-monomer selected from butene monomers or 1-hexene, where the polyethylene copolymer has a density in the range of from about 0.935 to about 0.950 g/cm3 and an I21/I5 in a range of about 18.0 to about 30.0. The film formed from the polyethylene copolymer has a dart drop impact (g/μm) that significantly greater as compared to a film of the polyethylene copolymer formed using a silyl chromate catalyst in place of the reduced chromium oxide catalyst. A method of making such films is also provided.
(FR) La présente invention concerne un film formé d’un copolymère de polyéthylène au moyen d’un catalyseur d’oxyde de chrome réduit, de monomères d’éthylène et d’un comonomère choisi parmi des monomères de butène ou de 1-hexène, le copolymère de polyéthylène ayant une masse volumique dans la plage d’environ 0,935 à environ 0,950 g/cm3 et un I21/I5 dans une plage d’environ 18,0 à environ 30,0. Le film formé à partir du copolymère de polyéthylène présente une résistance à la perforation (g/μm) qui est significativement plus élevée que celle d’un film du copolymère de polyéthylène formé au moyen d’un catalyseur de chromate de silyle à la place du catalyseur d’oxyde de chrome réduit. L’invention concerne en outre un procédé de fabrication de tels films.
