How are Poly bags made?
The first step in the manufacturing of a poly bag is the extrusion process. This process involves taking plastic resin, adding the color required, then extruding this resin into polyethylene film. This film is then converted into a roll. The roll is then taken to a printing press. The press is set up with printing plates that have your store name or logo engraved on the plates. The film is then printed with your name and rewound into a roll. This printed roll is then taken to a bag machine where the bag is produced to the specifications required, ie. size, handle type, gussets, etc. .
