A stand-up bag of a heat-sealable plastic film comprising two opposing side walls (1, 2) sealed together along the lateral edges thereof by means of side seams (5, 6), an inwardly folded bottom wall (4) provided between the lower portions of the side walls (1, 2) and sealed to the respective side walls (1, 2) along transverse bottom seams (7) and along bottom side seams, and an inwardly folded top wall (3) extending between the side walls and connected to the respective side walls (1, 2) along transverse top connections (11, 12) and sealed to the respective side walls (1, 2) along top side seams. One of the side walls (1) comprises a first side wall section (1a) and a second side wall section (1b) which overlaps the first side wall section (1a) in an overlapping area (15). In the overlapping area (15) the two side wall sections (1a, 1b) are connected by means of longitudinal peelable connections (19, 20) along the side seams (5, 6) and by means of a transverse peelable connection (18). The second side wall section (1b) extends a distance past the transverse peelable connection (18) to form a gripping member (21).

L'invention porte sur un sac à maintien vertical conçu dans un film plastique thermoscellable comprenant deux parois latérales opposées (1, 2) scellées le long de bords latéraux par des joints latéraux (5, 6), une paroi (4) inférieure repliée vers l'intérieur, formée entre les parties inférieures des parois latérales (1, 2) et scellée aux parois (1, 2) latérales respectives le long des joints (7) inférieurs transversaux et des joints latéraux inférieurs, et une paroi (3) supérieure repliée vers l'intérieur et s'étendant entre les parois latérales et raccordée aux parois (1, 2) latérales respectives le long de scellements (11, 12) supérieurs transversaux et scellée aux parois (1, 2) latérales respectives le long des joints latéraux supérieurs. L'une des parois (1) latérales comprend une première section (1a) et une seconde section (1b) qui chevauche la première (1a) dans une zone (15) de chevauchement. Dans cette zone de chevauchement (15), les deux sections latérales (1a, 1b) sont raccordées par des scellements (19, 20) longitudinaux détachables le long des joints latéraux (5, 6) et par un scellement (18) transversal détachable. La seconde section (1b) latérale s'étend sur une distance au-delà du scellement (18) transversal détachable de façon à former un élément (21) de préhension.
