Graham Packaging Company, L.P., a leading global producer of custom blow-molded plastic containers, has unveiled a new 48-ounce HDPE (high-density polyethylene) limited-edition "caricature" bottle to help build brand awareness for Hershey's Syrup. The bottle is whimsically molded in the shape of "Hershel Cow," a character Hershey Foods features in its print and television advertising.
