Packaging refers to the process of designing the product’s package such as container, wrapper, etc.
Functions of Packaging :

1. Product Identification                                                                                                      The package of a product helps the customer to easily identify the product in the market, e.g. Red Label tea in a red colour packing, Taj Mahal tea in blue box pack, etc.
2. Product Protection                                                                                                           The package of a product protects it from spoilage, breakage, pilferage, leakage, damage, etc. e.g. oil in plastic bottles.
3. Facilitating use of the Product                                                                                         The package of a product helps the consumer to open, handle and use the product more conveniently, e.g. toothpaste tubes, handwash soap dispenser, etc.
4. Product Promotion                                                                                                            An attractive package attracts the attention of people and at the same time, provides detailed information about the product, e.g. ferrero rocher chocolates.

The fine purple and gold packaging is meant to portray the rich and creamy taste of Cadbury chocolate.
