Abstract

L'invention concerne une sacoche de transport ayant une résistance et une capacité portante accrues en utilisant moins de matériau, et son procédé de production. Selon l'invention, lors de la production de la toile représentée à la figure 2, la première couche est constituée d'un film d'OPP (5)(polypropylène orienté) imprimé ou non imprimé, la deuxième couche est constituée d'un filet de PP (6) composé de filaments de PP (polypropylène), et la troisième couche est constituée de non-tissé de PP (7) qui est lié à une toile technique non-tissée, ou à des matériaux similaires. De la colle à base de solvant est utilisée en tant que matériau liant entre les couches.
