The invention relates to improvements to the main patent application, particularly as regards the application of the packaging to the packing of wine or other liquid products which have to be packaged in the absence of air. It relates to a parallelepipedal packing method and the packing thus obtained. The packing method of the present invention uses a bag 1 consisting of a flexible sheet which is folded and fastened over its periphery equipped with an open neck, and it is characterised in that the said bag 1 is pre-shaped into a parallelepipedal shape, giving it a certain consistency according to the said volume, and then the pre-shaped bag is filled and the neck is sealed. Pre-shaping is then performed with the aid of a shaper which positions stiffening elements over the periphery of the bag 1. The invention will be most particularly applicable to the packing of solid materials in bulk or of liquids. <IMAGE>
