An apparatus and methods for flame-perforating films. A preferred
embodiment of the apparatus includes a frame, support surface attached to
the frame, where the support surface includes a plurality of lowered
portions, a burner attached to the frame opposite the support surface,
where the burner supports a flame, and where the flame includes a flame
tip opposite the burner and a film contacting the support surface, where
the flame of the burner is in contact with the film, where the burner is
positioned such that the distance between an unimpinged flame tip of the
flame and the burner is at least one-third greater than the distance
between the film and the burner.
