ABSTRACT:
A package header arrangement includes a header with first and second opposing films, a tear bead and a support member. The support member is attached to the first film below the tear bead. The tear bead is disposed between the first and second films. When heat and pressure are applied to the first and second films in proximity to the tear bead, the tear bead scores the first and second films creating a breakable tear bead line. When heat and pressure are applied, the tear bead pushes aside the inner layer of the first and second films, weakening the film along the breakable tear bead line without harming the hermetic seal provided by the films. The breakable tear bead line tears easily because it does not have the tough, flexible inner layer of the films to aid in tear resistance. The breakable tear bead line also provides an even tear along a straight line. The support member provides support while tearing along the breakable tear bead line.
