Abstract
Abstract A plastic bag that is closed along three side edges and open at one edge for receiving an article is provided with a pouch on one outer surface. The pouch is formed of a second plastic layer that is heat sealed to the bag, preferably coincidentally with two side edges thereof. The upper and lower unsealed edges of the plastic layer are folded over to define a member having spacedly confronting edges. A sheet bearing appropriate indicia may be positioned in the pouch and be removably captured by the folded over edges of the second plastic layer. The indicia bearing sheet is readily removable from the pouch without disturbing the contents of the bag.
