Abstract:
A bag may be formed from a tube of high strength packaging material by forming a heat seal in the end of the tube. As part of forming the heat seal, one or more supplying apparatuses, which may be air outlets, are positioned for being in opposing face-to-face relation with, and for causing heat transfer with, at least one outer portion of the tube while a transportation system transports the tube to a nipping apparatus.
