Title (EN) POLYPROPYLENE FILMS HAVING IMPROVED OPTICAL PROPERTIES
(FR) FILMS DE POLYPROPYLÈNE AUX PROPRIÉTÉS OPTIQUES AMÉLIORÉES
Abstract: front page image
(EN)The invention relates to polypropylene films having improved optical properties, in particular a reduced orange peel. The films contain polypropylene with an MFR of 3 - 22 g/10 min (230 °C/2.16 kg), a polydispersity (Mw/Mn) ≤7, an XCS content of ≤ 25 wt% and a porous inorganic antiblocking agent.
(FR)L'invention concerne des films de polypropylène aux propriétés optiques améliorées, dotées en particulier d'un effet de peau d'orange réduit. Les films précités contiennent un polypropylène qui possède une valeur MFR comprise entre 3 et 22 g/10 min (230 °C/2,16 kg), une polydispersité (Mw/Mn) ≤7, une teneur en XCS ≤ 25 pour cent en poids, et qui comprend un agent antiadhérent inorganique poreux.
