A packaging laminate for a packaging container for a food product, which packaging laminate comprises an outer polypropylene based heat sealable layer, a paper or paperboard based bulk layer, an aluminium gas barrier layer, and an inside comprising an inner polypropylene based heat sealable layer. The inner polypropylene based heat sealable layer is bonded to the aluminium gas barrier layer by intermediate layers of linear low density polyethylene and ethylene (meth)acrylic acid copolymer or other acid polymer, the ethylene (meth)acrylic acid copolymer or other acid polymer being directly bonded to the aluminium gas barrier layer. The invention also relates to a film intended to form the inside of the packaging laminate, a method in connection with the production of the packaging laminate, and a packaging container formed from the packaging laminate.
