Example Embodiment

[0045] The packaging material according to the present invention includes a core material layer, an outer layer and an inner layer, wherein the outer layer and the inner layer are applied to opposite sides of the core material layer. The outer layer applied on one side of the core material layer is adapted to provide the outer surface of the package to be produced, the outer surface and the outer layer facing the surrounding environment of the package. The inner layer is applied to the other side of the core material layer and is adapted to provide the inner surface of the package to be produced, the inner surface of which is in contact with the material contained in the package.

[0046] The core material may be a sheet, preferably made of plastic, paper, cardboard or cardboard.

[0047] The outer layer may include at least one layer of polymer material, which is applied to the core material layer. In addition, one of the layers constituting the outer layer may be a decorative la...

Abstract

The present invention relates to a packaging material comprising a core material layer having an area radially extending from an edge of a hole in said core material layer, wherein said area has a linearly or non-linearly decreasing core material layer thickness towards the edge of the hole. The invention further relates to a method for production of such a packaging material, and uses thereof.

Description

technical field [0001] The present invention relates to packaging materials and combinations suitable for caps or closures. Background technique [0002] Product containers with lids or closures are well known. When producing packaging materials that are subsequently folded into product containers, sensitive areas may arise in which different components and / or layers of the packaging material interact. [0003] The packaging material may comprise different layers. For example, the packaging material may comprise paperboard, wherein on one side thereof at least one decorative layer is applied, constituting the outer surface of the package, and on its other side comprises a polymeric composition or layer, optionally a protective film, for example a protective film is Aluminum, and the inner layer in contact with the product in the container that will contain the product. If the product container is suitable for a lid or closure, then adjustments to the packaging material wi...
