Abstract

Package material comprises one or more layers of plastic laminate, a first side, a second side and a penetration area (40). A weakening line (30) extends from the penetration area (40) and provides an opening area (12) in the package material. The package material comprises a plastic opening device (2), with a first and second portion (4) attached to the first and second side, respectively and a material bridge (45) penetrating through the penetration area (40). The second portion covers at least partly the penetration area and comprises a guiding portion (35, 36) extending from the penetration area (40) adjacent to the at least one weakening line (30) as to facilitate rupturing substantially along the at least one weakening line.
