Abstract (en)
[origin: EP1203725A1] A bag with quadrangular bottom is constituted by a substantially rectangular flexible sheet element (2) in which fold lines form and articulate, in a U-like shape, a substantially quadrangular central bottom (4) and two main faces, a front one and a rear one (6), which protrude symmetrically from two opposite sides of the bottom; the bottom and the main faces are extended at their sides by respective foldable flaps (4a, 5a, 6a), which can mutually overlap and form the sides (7) of the bag; elements for the lateral sealing of the bag are also provided. <IMAGE> <IMAGE>
