A packaging material, comprising:
- a laminate with a core material layer, an outer layer, and an inner layer and having a plurality of delimited areas configured to form faces of a package, wherein at least one delimited area is provided with at least one pre-laminated hole and a plurality of compressed features arranged adjacent and spaced apart from the at least one pre-laminated hole, the pre-laminated hole comprising the outer layer and the inner layer, and wherein each compressed feature comprises a length, the length equal to or greater than a diameter of the at least one pre-laminated hole.
A method for providing a packaging material, comprising:
- providing a core material layer with at least one hole;
- laminating the core material layer to form a laminated packaging material with a pre-laminated hole, the pre-laminated hole comprising an outer layer and an inner layer;
- and
- providing a plurality of compressed features adjacent and spaced apart from the pre-laminated hole prior to or after providing the core material layer with at least one hole, wherein each compressed feature comprises a length, the length equal to or greater than a diameter of the pre-laminated hole.
