Abstract

L'invention concerne un corps d'emballage pour articles absorbants, qui comporte un article absorbant (10) et une feuille d'emballage (20) stratifiés dans le sens de l'épaisseur. Une première section de pliage (51) dans le sens de la largeur et une seconde section de pliage (52) dans le sens de la largeur sont réunies par une première zone adhésive (151), et une première section de pliage (61) longitudinal et une seconde section de pliage (62) longitudinal sont réunies par une seconde zone adhésive (152) dans le sens de la largeur. Une région à tirer (62PR) est prévue dans la seconde section de pliage (62) longitudinal, ladite zone à tirer (62PR) étant tirée lorsque le corps d'emballage pour articles absorbants, dans un état plié, est déployé. Dans la feuille d'emballage (20), la distance la plus courte depuis la région à tirer (62R) jusqu'à une extrémité de référence (152Es) de la seconde zone adhésive (152) passant par une première ligne de pliage (FL1) longitudinal, est plus courte que la distance la plus courte depuis la région à tirer (62PR) jusqu'à l'extrémité de référence (152Es) passant par une deuxième ligne de pliage (FL2) longitudinal.
