Abstract

The invention relates to a sack (1) or a similar flexible package and a packing method based on the use of such a sack. The sack (1), which is intended for packing fine-ground material, is provided with a filling duct (3) leading inside the sack and made of flexible material and a bendable covering patch (12) protruding from the sack with the aid of which the end (11) of the filling duct can be closed after the filling of the sack. It is essential to the invention that the filing duct (3) extends at least to the bending line (13) of the covering patch (12) and preferably past it and that the filling duct (3) is, at least at the end thereof, narrower than the covering patch (12). Thus the covering patch (12) can be bent against the surface of the sack and attached thereto in such a way that it forms a uniform closing zone closing the end (11) of the filling duct in a cross-direction and extending to each side thereof.
