摘要： 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.

摘要： A packaging laminate for a retortable or hot fillable packaging container comprises a core layer of paper or paper board, a first outer liquid-tight coating based on polypropylene on the inside of the packaging laminate, a second outer liquid-tight coating and based on polypropylene on the outside of the packaging laminate, an aluminium foil serving as gas barrier between the core layer and said first outer liquid-tight coating based on polypropylene. A layer of polar polymer material serving as barrier against acidic compounds is provided between the aluminium foil and said first outer liquid-tight coating based on polypropylene. The present invention also relates to the packaging container proper as well as to a method in its production.
