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 produced from a web-shaped multilayer material and in the form of a sleeve, which, at one end, is connected to a bottom portion and at the other end is connected to a top portion produced from a blow molded thermoplastic material. The casing is formed by winding of the multilayer material into sleeve form and liquid-tight sealing of the material edges to a joint seam extending longitudinally of the sleeve, the top portion being manufactured in that thermoplastic material is extruded to form a hose which is blow molded into continuous top portions which are separated from one another and connected to the sleeve.
