ABSTRACT:
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.
