They were prone to spoilage and contamination by maggots and rodents. That's also where the term scraping the bottom of the barrel from and it's associated with something that is not good because by the time they get to the bottom of the cracker barrel, the crackers down there were not good to eat.

It was not easy to ship crackers in barrels from the east coast to other parts of the country and expect the product to stay fresh before it gets to the customer. National Biscuit Company invented and patented the inner seal. A cardboard box lined with a inner seal of wax paper and then vacuum packed to protect the crackers from spoilage.
