ABSTRACT:
This invention is a novel plastic bag and method of making it with a handle that extends upward through a folded-back top compartment, and the end of a front of the bag has a pocket with a similar folded-over top edge of the back of the bag. The bags of this invention are made from a continuous sheet, preferably a roll of plastic web that has its opposite side edges folded inwardly along opposite edges of the web to make the folded edges at the front and back sides of the bag. The web is then folded along its longitudinal center region with a gusset that forms the bottom of each bag. The bags have surfaces that are welded together to join areas of the front and of the back where necessary to weld plastic areas together, and certain areas do not weld where the plastic sheet is coated on areas that prevent heat applied to the plastic from fusing together.
