Packaging engineering, also package engineering, packaging technology 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, project management, food safety, robotics, RFID tags, quality management, package testing, packaging machinery, tamper-evident methods, recycling, computer-aided design, etc.
Rutgers University offers the nation’s only packaging program housed in an engineering school, since 1965.  Unique from other engineering disciplines in its dynamic, the Packaging Engineering Concentration prepares engineering students by drawing heavily from each of the chemical, industrial, materials and mechanical engineering fields. It requires a strong background in mathematics, chemistry, physics, and computers. The Rutgers Packaging Engineering Program also offers an 18 credit Graduate Packaging Engineering Certificate.
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. It hosts the Philippine Center for Packaging Engineering and Technology that provides packaging engineering services and consultancy. University alumnus Dr. Lejo C. Brana, considered the founder of the packaging engineering program of the University, is a United States Hall of Famer in Packaging Engineering.
In the United Kingdom, the Packaging Society, formerly the Institute of Packaging, offers the industry-standard Diploma in Packaging Technology. In India, The Indian institute of Packaging established in 1966, a national apex body which was set up in 1966 by the packaging and allied industries and the Ministry of Commerce, Government of India offers the 2 years Postgraduate Diploma in packaging as well as Graduate Diploma and certificate courses.It has its centers in Mumbai, Kolkata, chennai, Hyderabad and Delhi.
