The Display of Packages in Retail Stores and the Principal Display Panel Requirement for Packaged Goods
David A. Sefcik
This article provides information on two related but distinctly different packaging and labeling issues. The first relates to the retail display of packages. The second explains the Uniform Packaging and Labeling Regulation's requirements for determining the Principal Display Panel (PDP) of a package, and some possible solutions to a reoccurring problem involving PDP placement on so called "fragile" (e.g., bakery) products are also provided.
