The present invention relates to a multi-layered composite bag used to store bulk type products such as pet food, seeds, fertilizer, cereals, grains, charcoal, sand, gravel, and other bulk products, including without limitation bulk products intended for human and non- human consumption, and provides a more efficient manufacturing process than using a paper/plastic structure. The present invention provides a bag [10] comprising a middle layer of woven mesh tubing [20] to which an outer layer of solid plastic film [30] is adhered using polypropylene or other polylaminates [40].
La présente invention concerne un sac composite multicouche utilisé pour le stockage de produits en vrac tels que des aliments pour animaux de compagnie, des graines, des engrais, des céréales, des grains, du charbon de bois, du sable, du gravier, etc. et également, et de manière non exhaustive, des produits en vrac destinés à la consommation humaine et non humaine. Issu d'un procédé de fabrication plus efficace que celui des structures en papier/plastique, le sac de l'invention comprend une couche centrale d'éléments tubulaires tissés sur laquelle est collé un film plastique plein au moyen de polypropylène ou d'autres polyaminates.
