Abstract
Improvements in the construction of bags of plastic material or the like, constituted by a tubular piece or by a sheet reduced to a tubular shape, characterized in that said bags are closed at one end, which constitutes the bottom of the bag, by means of welds that create less a channel of discharge of the air and because they have at the other end the edges welded together except for a distance, intended to constitute the filling mouth of the bag, said section being welded, once the bag is filled, by means of at least one further welding that creates at least one other air discharge channel enclosed within the bag.
