4. Functions of Packaging
Packaging Serves FOUR Functions
Containment – Products must be contained in order to be moved from the factory to the grocery store to the pantry shelf.

5. Functions of Packaging
Protection – Products must be protected from physical damage (e.g. drops or falls), environmental effects (e.g. water, light, or oxygen), and contaminants (e.g. dust, microorganisms, or chemicals).

7. Functions of Packaging
Communication – The package must attract consumers for purchase. It also communicates product information such as nutritional content, ingredients, and net weight.

8. Functions of Packaging
Convenience – The package must conveniently fit into the consumer’s lifestyle.

13. Sustainable Packaging
Environmentally friendly packaging causes less damage to the environment. There are three types:
Reusable packaging can be cleaned and re-used. For example, glass milk bottles are reused.
Recyclable packaging is made of materials that can be used again, usually after processing. Recyclable materials include glass, metal, card and paper.
Biodegradable packaging will easily break down in the soil or the atmosphere

14. Primary packaging is seen at the point of sale
Primary packaging is seen at the point of sale. It needs to contain and protect the food product, as well as display it and provide information.

15. Secondary packaging is the middle layer of packaging - for example a cardboard box with a number of identical products inside.

16. Transit packaging is the outer container that allows easier handling during transfer between factory, distribution centres and retailers
