Help your students understand the science behind something they see every day but rarely think about—food packaging. This engaging and easy-to-follow eBook introduces the essential functions of packaging, from protecting and preserving food to communicating important information and supporting sustainability. Students will explore common packaging materials like plastic, glass, metal, and paper, and learn why each is used in different situations.

What sets this resource apart is its clear explanation of how packaging fits into the larger food system. It goes beyond basic concepts to show how packaging helps detect food fraud, track products through the supply chain, and support food safety using modern tools like QR codes, RFID tags, and smart packaging technologies.

Written in a clear, conversational style, this eBook is ideal for middle and high school classrooms, especially for teachers who want a ready-to-use resource that explains the “why” behind packaging decisions. Whether used as a lesson supplement, independent reading, or part of a unit, this resource helps students connect science to real-world food systems in a meaningful way.
