Packaging is an essential medium for preserving food quality, minimising food wastage and reducing preservatives used in food. The packaging serves the important function of containing the food, protecting against chemical and physical damage whilst providing information essential to consumers and marketers.

Food engineering is a multidisciplinary field which combines microbiology, applied physical sciences, chemistry and engineering for food and related industries. Food engineers are employed in food processing, food machinery, packaging, ingredient manufacturing, instrumentation, and control.

The main types of food packaging are glass containers, vacuum packaging, tetra pack containers, plastic packaging, tin packaging, cardboard packaging, wood packaging, long-life packaging, ice cream packaging, metal packaging, laminated packaging, and juice packaging.
