A packaging material for allowing sterilization of contents of a package comprising packaging manufactured from the packaging material, wherein the packaging material comprises:
- a porous film comprising a high density polyethylene, wherein the porous film shows a microbial barrier log retention value of 3 or more according to ASTM F1608 and a Bendtsen air permeability of 600 ml/min or more according to ISO 5636-3, and
- a laminate comprising a heat sealing polyethylene film adhered to either an oriented polyethylene film or to a layer of high density polyethylene,
- wherein at least a region of said heat sealing polyethylene film has been heat sealed to at least a region of said porous film.
A packaging for the manufacture of a package, wherein the packaging comprises a packaging material that comprises:
- a porous film comprising a high density polyethylene, wherein the porous film shows a microbial barrier log retention value of 3 or more according to ASTM F1608 and a Bendtsen air permeability of 600 ml/min or more according to ISO 5636-3, and
