Abstract
A platen seal for a vertical form fill and seal machine which uses unsupported polyethylene films to wrap products which require absolute seal integrity. The platen includes a set of lateral seal members in the form of wings on the top and bottom of the platen to seal gaps between platen segments without causing burn through of the film.
