Below is a list of Plastic Packaging manufacturers from Winston-Salem, North Carolina. Plastic packaging encompasses all storage or containment devices produced through the manipulation of any number of polymer resins. While the term 'plastics' applies to a diverse group of materials, they are in general light weight, durable and inexpensive to produce. For these reasons and more, as much as 53% of all packaged goods are contained in plastics. Because plastics can also be made clear, they are ideal for easy product display and identification as well.
