Abstract

A sheet packaging material includes fold lines along which the sheet packaging material is foldable to form a sealed package containing a pourable food product. The packaging material comprises at least one base layer that imparts stiffness, at least one lamination layer applied to and covering the base layer; and a removable portion which, in use, is partly detachable from a remainder of the sheet packaging material and foldable at a folding zone to free a pour opening by which to pour the food product from the package. The removable portion comprises at least one aperture formed at least in the base layer and covered by a cover material, and the removable portion is crossed by one of the fold lines defining in use an edge between two walls of the package.
