Packaging engineering, also package engineering and packaging science, is a broad topic ranging from design conceptualization to product placement. All steps along the manufacturing process, and more, must be taken into account in the design of the package for any given product. Package engineering includes industry-specific aspects of industrial engineering, marketing, materials science, industrial design and logistics. Packaging engineers must interact with research & development, manufacturing, marketing, graphic design, regulatory, purchasing, planning and so on. The package must sell and protect the product, while maintaining an efficient, cost-effective process cycle.
Engineers develop packages from a wide variety of rigid and flexible materials. Some materials have scores or creases to allow controlled folding into package shapes (sometimes resembling origami). Packaging involves extrusion, thermoforming, molding and other processing technologies. Packages are often developed for high speed fabrication, filling, processing, and shipment. Packaging engineers use principles of structural analysis and thermal analysis in their evaluations.
Formal packaging programs might be listed as package engineering, packaging science, packaging technology, etc. BE, BS, MS, and PhD programs are available. Students in a packaging program typically begin with generalized science, business, and engineering classes before progressing into industry-specific topics such as shelf life stability, corrugated box design, cushioning, engineering design, labeling regulations, distribution testing, project management, food safety, robotics, RFID tags, quality management, package testing, packaging machinery, tamper-evident methods, recycling, computer-aided design, etc.
Clemson University offers a degree in Packaging Science. There are also master's and doctorate programs. The undergraduate program at Clemson requires student's to take at least one six-month co-op for the degree.
Rochester Institute of Technology's Packaging Science program was first established in 1972. It is an interdisciplinary degree that leads to either a bachelors or masters of science. RIT requires all Packaging Science students to complete a 6 month internship/Co-op. 
Central Philippine University in Iloilo City in the Philippines in 2006, is the first to offer (and considered as the first in Asia) in the Philippines a (5-6 year) bachelor's degree in Packaging Engineering.
