A flexible packaging for liquids, such as milk, can according to the invention be produced from a laminated foil layer with unlaminated portions (5) which extend in parallel from the bottom of the packaging (1) and upwards, and which form channels (6) between the foil layers (2, 3). By filling these channels (6) with air, and thereafter closing them by means of a weld seam (7) in the formation of closed chambers, the air pockets will give the packaging a shape stability and stiffness which enables the packaging to be used for liquids without it collapsing while being emptied. In other words, the packaging functions in the same way as a rigid form of packaging. The packaging according to the invention can hereby be used in a simple and inexpensive manner for the packaging of consumer goods in relatively large amounts, i.e. right up to several litres per packaging, and with the possibility of providing the liquid with the best possible protection. |
