A polymeric film comprising from 0.0005 % to 2 % by weight of filler particles having a volume distributed median particle diameter of from 0.1 to 12.5 µm. The filler particles can be obtained by calcining precursor silicone resin particles prior to incorporation into the film polymer. The polymeric film is preferably a polyester film.
La présente invention concerne un film polymère comprenant 0,0005 % à 2 % de particules de charge dont le diamètre particulaire médian réparti dans le volume est compris entre 0,1 et 12,5 µm. On peut produire ces particules de charge en calcinant, avant de les incorporer dans le film polymère, un précurseur à base de particules en résine de silicone. Le film polymère est de préférence un film de polyester.
