Abstract
A self-standing bag containing a generally rectangular-shaped bale of compressed loose material. The self-standing bag has a generally elongated shape with a height and a base section defined by a first side and a second side. The bag is formed from a tube of impervious flexible material defining an enclosure completely enclosing the bale. The bag comprises a flat bottom end, preferably closed by an end seal. The bottom end is normal to a longitudinal axis of the tube and enables the bag to stand upright. The self-standing bag further comprises a sealed top end. A method for producing such a self-standing bag of compressed loose material is also disclosed.
