The present invention relates to an opening device comprising a first portion on one side of a fibre based packaging laminate and a second portion on an opposite side of the fibre based packaging laminate, the first and second portion being formed in one and the same piece and joined by at least one material bridge extending through the packaging laminate. The present invention also relates to a method for manufacturing the opening device and to a packaging material to be used is such a method.

Opening device, method for manufacturing such opening device and packaging material for use in said method

Packaging laminate for a packaging container for a fermented liquid milk product, such as soured milk, yogurt and cr&#xe8;me fra&#xee;che. The packaging laminate has a paper layer, and outer liquid-tight layers on both sides of the paper layer. One of the outer layers of the packaging laminate has a whey protein surface coating.

Packaging laminate and packaging container for a fermented liquid milk product

A packaging laminate for a retortable packaging container, the packaging laminate () including a paper or paperboard layer (), outer, liquid-tight coatings () and an aluminium foil () serving as gas barrier between the paper or paperboard layer () and one of the two outer liquid-tight coatings (). In order to compensate for or counteract possible loss of gas tightness because of crack formations or similar untightness in the tensile-sensitive aluminium foil (), the packaging laminate () includes at least one additional layer () serving as gas barrier between the paper or paperboard layer () and the aluminium foil (). Preferably, said at least one additional gas barrier layer () is bonded to the paper or paperboard layer () by an interjacent lamination or adhesive layer () of polypropylene or other olefin polymer, whereby the thickness or quantity of the additional gas barrier layer () may be reduced without deterioration in gas tightness properties in the finished packaging container.

Packaging laminate for a retortable packaging container

The disclosure relates to a packaging laminate for a retortable packaging container comprising a core layer (), outer, liquid-tight coatings (and) and a gas barrier () disposed between the one coating () and the core layer (). Between the gas barrier () and the core layer (), there is a layer () of a lamination or sealing agent of such a nature that the lamination or sealing agent has a melting point which is higher than the maximum temperature to which the retortable packaging container is to be subjected during a normal heat treatment in a retort. The lamination or sealing agent in the layer () may, for example, be a polypropylene with a melting point of above 130&#xb0; C.
