Abstract
An improved bag-container, of the type comprising a tubular body of preferably plastic material, closed at one end per welding line, essentially characterized by the fact that it presents on the longitudinal edges or folds of the bag, resulting from the flattened shape of the bag. The same, continuous areas of greater thickness than the rest of the material of the bag, whose areas are reinforcements that prevent tearing of the aforementioned folds.
