ABSTRACT:
Packaging containers for beverages, for example milk or juice, as well as blanks for producing the packaging containers, are often manufactured from paper-plastic laminate which, by fold forming and sealing, is given the desired container configuration, normally parallelepipedic. With the aid of a specifically designed pattern of fold or crease lines which divide the material into, for example, six side panels (1) and associated primary end panels (7) and secondary end panels (8), respectively, prismatic, preferably hexagonal containers may instead be produced using substantially known methods.
