Abstract
A zipper closure for a polymeric package includes a plurality of profile members on a first polymeric surface, where one and not more than one of these plurality of profile members is colored differently from the remaining profile members on the same polymeric surface. The differently colored profile members provide a visual reference for properly orienting the zipper closure to the polymeric packaging during manufacture.
