Abstract
(EN)
Provided are a resin composition for a breathable film with which it is possible to easily obtain a breathable film having the desired breathability without restrictions on the material composition, a breathable film, and a method for producing a breathable film. In a resin composition for a breathable film containing a thermoplastic resin and an inorganic substance powder in a proportion of 50:50-10:90 by mass ratio, the inorganic substance powder is calcium carbonate particles and the water content of the calcium carbonate particles according to JIS K0068 is adjusted in accordance with the desired air permeability of the breathable film according to JIS P8117.

L'invention concerne une composition de résine pour film respirant permettant d'obtenir facilement un film respirant présentant la respirabilité souhaitée sans restrictions sur la composition du matériau, un film respirant et un procédé de production d'un film respirant. Dans une composition de résine pour film respirant contenant une résine thermoplastique et une poudre de substance inorganique selon une proportion de 50:50 à 10:90 selon un rapport en masse, la poudre de substance inorganique est constituée de particules de carbonate de calcium et la teneur en eau des particules de carbonate de calcium selon la norme JIS K0068 est ajustée en fonction de la perméabilité à l'air souhaitée du film respirant selon la norme JIS P8117.
(JA)
材料組成の制約がなく、容易に所望の通気性能を有する通気性フィルムを得ることが出来る通気性フィルム用樹脂組成物、通気性フィルム及びその製法を提供する。 熱可塑性樹脂と無機物質粉末とを質量比50:50~10:90の割合で含有する通気性フィルム用樹脂組成物において、前記無機物質粉末が炭酸カルシウム粒子であり、通気性フィルムにおける所望のJIS P8117の透気度に応じて、前記炭酸カルシウム粒子のJIS K0068による水分を調整する。
