An inorganic particulate material containing at least 95 % by weight calcium carbonate suitable for use as a mineral filler in the manufacture of thermoplastic film products which inorganic particulate material is in the form of a composition in which it is mixed together with a desiccant additive present in an amount which is not greater than 10 % by weight based on the weight of the inorganic particulate material. L'invention se rapporte à une matière particulaire inorganique contenant au moins 95 % en poids de carbonate de calcium, conçue pour servir de charge minérale dans la fabrication des produits de type films thermoplastiques. Ladite matière particulaire inorganique se présente sous la forme d'une composition dans laquelle elle est mélangée à un additif desséchant présent en quantité ne dépassant pas 10 % en poids par rapport au poids total de la matière particulaire inorganique.
