Abstract:
A process of manufacturing a roll of plastic bags. The process includes forming a tubular blown film, and collapsing the tubular blown film so that the tubular blown film includes a first side, a second side, a first edge, and a second edge. Openings are cut in the collapsed tubular blown film, and sealing closure mechanisms are inserted through the openings into the collapsed tubular blown film. The sealing closure mechanisms are then fixed to the collapsed tubular blown film.
