| Abstract Scope |
Lacquered tinplate is widely used in the manufacturing of containers for food and beverage packaging. The containers are intended to preserve the contentīs edibility characteristics for a long period of time. Although the tinplate container industry and the corresponding involved technology is well established, failures related to defective materials or inadequate manufacturing operations frequently occur, generating important economic losses and legal issues, particularly in those cases involving changes in the organoleptic attributes and self-life of food. In this presentation a set of cases of failures in food containers will be presented and thoroughly discussed. Defects such as black spots, corrosion pits, lacquer discontinuities, manufacturing defects, and operation related defects, and corresponding effect on container performance will be examined. The failure mechanisms will be analyzed and recommendations for avoiding failure to occur again will be presented. |
