Abstract

A film wrapper (99) comprises a tear tape (30) and at least one weakening line (10, 12) next to the tear tape (30) , the longitudinal axis of the at least one weakening line (10, 12) being substantially perpendicular to the tear tape (30) (perpendicular weakening lines (10, 12)) . An article is wrapped into the film wrapper. A multi- bladed knife (100) used for producing the film wrapper comprises a U-shaped or V-shaped first blade (110) and a second linear blade (112) parallel to the longitudinal axis of said first blade (110) and a third linear blade (111) perpendicular to the longitudinal axis of the first blade (110) .
