Roles of Packaging

Roles of Packaging

Packaging has no meaning without the product for which it was designed. Its primary function is to preserve and protect the product throughout the manufacturing, transport, storage and consumption chain. In other words, it prevents part or the entire product from going to waste, which would result in an economic and environmental loss. But good packaging also guarantees the health and safety of consumers. Finally, packaging fulfils other functions: it carries information, acts as a marketing tool, and enables products to be offered in different formats and various portions, corresponding to the consumer's needs.

How packaging can reduce food waste 

  • Packaging requires an average of 5% of the energy needed during the life cycle of a food product.
  • In developing countries, 25 to 50% of the food is wasted even before it reaches the consumer because of inappropriate transport, storage and packaging.
  • In our part of the world, this figure varies between 2 and 3%. Nevertheless, a lot of food is still wasted after purchase.

Packaging is becoming increasingly technical and plays a role of growing importance in reducing food waste:

It delays food degradation due to bacteria and shocks


It presents the products in various portions


It extends the lifetime of a product (MAP, vacuum packaging, reclosable packaging)


It evolves in order to be emptied better


It communicates storage and usage conditions (storage temperature, use-by date, etc.)
