In the history of food packaging supplies, the type of container used to ship products initially took a back seat to the actual sales of the products themselves. Consideration about the type of shipping container to be used was more of an after thought than a major focus of early manufacturers. Up to the end of the 19th century processors tended to use easy access materials for transporting their goods to market. The types of containers used were mostly made out of wood, cork, and clay. In the 20th century, there was a shift in materials use for food shipment and the bulk of those made were constructed from paper, glass, and metals. packaging supplies
