Abstract

L'invention concerne des sacs à fond plat composés d'un matériau souple, ainsi que des procédés permettant de fabriquer ces sacs à fond plat. Plus particulièrement, les sacs à fond plat décrits dans cette invention présentent au moins une surface essentiellement plane qui est exempte de joints et de plis. Lorsque le sac est rempli avec une substance fluide, la pression exercée par le fluide sur les surfaces planes permet au sac d'être autoporteur. En outre, le fond plat comprend au moins une structure de contour qui définit la géométrie du sac et qui permet également au sac à fond plat d'être autoporteur même lorsque le sac est partiellement rempli avec la substance fluide.
