Abstract
Package material comprises one or more layers of plastic laminate, a first side, a second side and an penetration area (). Two weakening lines () extend from the penetration area () creating a space in between and thus forming an opening ( ) in the package material. The package material comprises a plastic opening device ( ), with a first and second portion ( ) attached to the first and second side, respectively and a material bridge ( ) penetrating through the penetration area (). The second portion covers at least partly the penetration area and comprises a guiding portion ( ) extending from the penetration area () onto the space adjacent and to the weakening lines () as to facilitate rupturing substantially along the at least one weakening line.
