ABSTRACT OF THE DISCLOSURE A packaging laminate for a liquid-tight, configurationally stable packaging container possessing good fat resistance properties. The packaging laminate (10) has a core layer (11) of paper or paperboard and outer liquid-tight films or coatings (12 and 13) of thermoplastic, preferably polyethylene. Between the core layer (11) and the one outer thermoplastic film (12), there is a layer (14) of greaseproof paper which is bonded to the core layer (11) via an interjacent layer (15) of binder or sealant plastic in order to impart fat resistance to the packaging laminate. Between the core layer (11) and the second outer thermoplastic film (13), there is an aluminium foil (16) which is bonded to the core layer (11) via an interjacent layer (17) of binder or sealant plastic, whereby the packaging laminate is given excellent oxygen gas barrier properties.
