Abstract

The disclosure relates to a packaging laminate (10; 20; 30) intended for the production of packaging containers possessing superior release properties vis-à-vis solid or semi-solid food products such as, for example, various types of cheese. The packaging laminate comprises a core layer (11; 21; 31) and an outer layer (12; 22; 32), the outer layer consisting of a polymer selected from homo- or copolymers of ethylene and propylene or mixtures of such polymers, and also glyceryl monostearate (GMS). The core layer may consist of a thermoformable plastic such as polypropylene, polystyrene, HDPE or PET, or of a fibre-based layer of paper or paperboard. The outer layer of polyethylene and/or polypropylene forms the inside layer in a packaging container produced from the packaging laminate and contains approximately 0.1-3 preferably approximately 0.5-2.5 weight per cent of GMS. The packaging laminate may also include a gas barrier layer (23) of, for example, aluminium foil, EVOH or PVOH disposed between the core layer and an outer layer. Such a packaging laminate makes for the production of packaging containers by means of thermoforming or fold-forming, respectively.
