A packaging bag is provided which is particularly adapted for insertion into a publication which is folded in its final form, the packaging bag comprising two sealed envelopes attached to each other along one margin of said envelopes and separated from each other by a fastening area. The packaging bag may be made by placing insert material inside a tube, the tube then being sealed widthwise periodically along its length to form a plurality of compartments which are separated from each other by at least one seal. Subsequently the tube is cut widthwise periodically along its length so that the tube has two to four compartments between adjacent cuts.
