A method and apparatus for sealing a drawtape to a hem of a thermoplastic film structure is disclosed. The thermoplastic film structure includes a panel, the hem, and the drawtape. The hem is formed along one end of the panel, and the drawtape is housed within the hem. In the method, the film structure is conveyed to a stationary heat sealer that includes a stationary heated block and a hot air blower spaced from the heated block. The film structure is momentarily stopped at the stationary heat sealer with hem disposed between the heated block and the hot air blower. While the film structure is stopped, the hot air blower blows heated air onto the hem to force the hem against the heated block, thereby sealing the drawtape to the hem.
