ABSTRACT:
An apparatus for sealing and severing a web of film is provided. The apparatus includes a sealing bar having a body portion including first and second sidewalls and a top portion for melting and severing a portion of a web of film. A backup member is provided located on an opposite side of the film from the sealing bar for urging the film against a portion of the sealing bar. The apparatus also includes a holder for holding the sealing bar, the holder includes a first side and a second side that define a center region for receiving at least a portion of the body of the sealing bar, and first and second sides having shoulders. The shoulders and top portion of the sealing bar are so constructed and arranged that they deflect a bead generated at a molten area of the film when the film is sealed and severed and substantially limit the creation of a resultant bead in a final cooled product.
