A bag (10) for a granular material (12), comprising: a body (20) defining a volume and formed of a woven polymer material, the body (20) comprising a laminated layer arranged along at least an outer surface (22) of the body (20) located on the opposite side of the volume, the body (20) presenting end portions (30) disposed at opposed extremities (24) thereof, one of the end portions (30) forming a structure (34) presenting an inner surface (37) and arranged to accommodate an outer mating surface (44) of a valve (40), the valve (40) presenting an inner filling surface (42) opposed to the outer mating surface (44), the valve (40) being made of a non-woven fabric (46) and presenting a first position wherein the valve (40) is opened and forms a passageway (36) delimited by the inner filling surface (42) allowing for filling the volume with the granular material (12), and a second position wherein the valve (40) and the passageway (36) are closed in order to seal the bag (10), the valve (40) moving from the first position to the second position upon the granular material (12) within the body (20) abutting against the structure (34). |
