Cadbury Dairy Milk has consistently changed its packaging over time. It first used purple and gold packaging in 1915 and the iconic Cadbury script logo was introduced. In the 1940s, an industrial designer created new designs using traditional purple and gold for milk chocolate. Currently, gold foil is used to pack the chocolate with an outer paper and plastic wrapper. Packaging is an important part of marketing and brand identification, protecting the product while communicating important information to consumers.
