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.

A process of manufacturing a roll of plastic bags, the process comprising:
- forming a tubular blown film;
- 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;
- perforating the first side of the collapsed tubular blown film to form a plurality of perforation lines;
- perforating the second side of the collapsed tubular blown film to form a plurality of perforation lines;
- cutting openings in the collapsed tubular blown film, each opening being provided at a position adjacent to one of the plurality of perforation lines;
- inserting sealing closure mechanisms through the openings into the collapsed tubular blown film;
- fixing the sealing closure mechanisms to the collapsed tubular blown film;
- connecting the first and second sides of the collapsed tubular blown film to form a plurality of seals, each seal of the plurality of seals extending from the first edge of the collapsed tubular blown film to the second edge of the collapsed tubular blown film;
- and
- winding the collapsed tubular blown film into a roll.
