Abstract
The disclosure relates to a packaging container and a method of producing a packaging container for liquid contents. The packaging container has a casing (2) produced from a web-shaped multilayer material and in the form of a sleeve, which, at one end, is connected to a bottom portion (4) and at the other end is connected to a top portion (3) produced from blow moulded thermoplastic material. The casing (2) is formed by winding of the multilayer material into sleeve form and liquid-tight sealing of the material edges to a joint seam (9) extending longitudinally of the sleeve, the top portion (3) being manufactured in that thermoplastic material is extruded to form a hose (15) which is blow moulded into continuous top portions which are separated from one another and connected to the sleeve.
