Abstract

L'invention concerne l'utilisation d'une matière à mouler composée de : 1 un polyéthylène spécial, à savoir un polyéthylène qui 1.1 est préparé au moyen d'un catalyseur contenant du chrome, 1.2 a une certaine densité, 1.3 présente un indice de fusion sélectionné et 1.4 possède une viscosité en solution particulière, 2 un additif spécial, à savoir un tri-(2,4-dialcoyl-phényl)-phosphite et 3 le cas échéant, des additifs usuels appropriés, pour la fabrication de feuilles minces et très minces étirées biaxialement d'après le procédé du soufflage.The invention relates to the use of a molding material composed of: 1 a special polyethylene, namely a polyethylene which 1.1 is prepared by means of a catalyst containing chromium, 1.2 has a certain density, 1.3 has an index of selected fusion and 1.4 has a particular solution viscosity, 2 a special additive, namely a tri- (2,4-dialkoyl-phenyl) -phosphite and 3, where appropriate, customary suitable additives, for the manufacture of thin sheets and very thin biaxially stretched by the blowing process.
