Abstract:
1. A method of forming a container comprising the steps of: providing at least one film; heating at least a portion of the film against a heated roller; forcing the film into contact with an embossing roller, to in turn, continuously deform-at least a portion of the surface of the at least one film into a plurality of peaks and valleys; accumulating film after the step of surface deforming; indexing the film to a flexible container sealing assembly; sequentially activating the flexible container sealing assembly to form sequential containers; separating the film from the heated roller in the event that the step of providing the at least one film is stopped; reversing the film so that the portion of film that was against the embossing roller is directed backwards so as to be positioned at the heated roller to, in turn, facilitate the reheating of film which had been heated prior to the step of separating but which had not undergone the step of forcing, to in turn, maintain a substantially continuous embossing of peaks and valleys; and engaging the film with the heated roller when the method is restarted, at the location where the embossing ceased on the film, to reheat the location, to in turn, render a substantially continuous embossing of peaks and valleys.
