A packaging label includes a first portion with permanent pressure sensitive adhesive on its bottom face and a second portion substantially perpendicular to the first portion and having permanent pressure sensitive adhesive on the bottom face remote from the first portion. The second portion typically includes nutritional information and bar coding since the label is typically used with clam shell plastic packages for fruits or other food items. The first portion of the label is adhesively secured to the lid of a clam shell container and after the container is filled with food items, the lid is closed, the second portion of the label is unfolded from a compact position which facilitates stacking and transportation, and the adhesive on the second portion is secured to the bottom of the container, holding the lid closed. The bar coding is preferably on the top face of the second portion opposite the adhesive so that it can be scanned merely by dragging the bottom of the container over a scanner (e.g. in a grocery store).
