<p>An apparatus and method for reducing stress marks and pleats on a package. The apparatus includes the use of an elongated filling tube. The dimensions of the elongated filling tube reduce the stress on the film as it is being formed around the filling tube. Further, the dimensions of the elongated filling tube prevent the formation of pleats as the sealing jaws must travel a decreased distance to seal, and the filling tube cross section better resembles the final package.</p> |
