Food packaging is an essential technique for preserving food quality, minimising food wastage and reducing the use of additives. The food package serves the important function of containing the food, protecting against chemical and physical damage and providing convenience in using the product information to the consumers.
Whether it's a can, glass bottle or jar or cardboard, packaging of our foods helps to protect it from contamination with microorganisms, pests and other contaminants. Packaging also helps to protect the form, shape and texture of the food inside, prevents the loss of flavours and odours, extends shelf life and regulates the water or moisture content of the food.In some cases, the choice of packaging material may affect the nutritional quality of a product. For example, opaque packaging such as cardboard cartons on milk products means that less of the light-sensitive vitamin riboflavin is lost from exposure to sunlight.
Packaging also provides an important medium whereby manufacturers can provide information on product features, nutritional contents and ingredient information.
