Said sheet is folded along at least one line, transversal to the longitudinal axis joining said handles. Said line forms the continuous and jointless bottom, and the lateral edges of said sheet are coupled with glue by overlapping to obtain the two vertical closed sides of the bag. The bottom is folded to form a bellows towards the inside of the bag, and each one of said handles is applied to the surface of said sheet facing the inside of the bag, wherein said opposite edges defining the upper edge of the bag are folded one or more times towards the inside and/or towards the outside in order to reinforce said handle.</p> |
