In addition to the development of the types, colors, and flavors of chocolate, the wrappers of the product has also changed through time in a way that reflects the competition among the chocolate industry’s market leaders. The main reason of this competition was to gain customers’ satisfaction and to draw their attention in market with a wide range of options.
In 1840, packaging of candies and chocolate bars began aiming at preserving the desired flavor and keeping the chocolate bars in desired acceptable conditions. After sixty years, huge competitors such as Cadbury, Harshey and Nestle started wrapping the small chocolate bars as regular part of the packaging process before selling them in the market. A new product emerged after thirty years in this business, moisture-resistant cellophane, which became a must in the chocolate industry to keep the chocolate bars in a good situation.
Later, wrapping became more artistic and much elaborated. Colored wrappers, 3D logos, golden letters, and many other creative details were introduced. Common wrapping styles included envelopes, sleeves, easy-to-open wrappers, and easy-to-tear edges were all introduced, for example.
Cadbury, the British market leader, added price and weight to the wrappers in 1933 and was very welcomed by the consumers. In 1973, Hershey printed the ingredients of the product and the printing of the Universal Product Code UPC, barcode, on all covers and wrappers. After the successful Cadbury’s marketing strategy of printing the shape of the chocolate bar on the covers in 1999, most international companies followed and did the same to attract more customers.
