Another functional aspect of product packaging is how it promotes and displays the product within. Many products, particularly food products, include a description of ingredients and nutritional information on the packaging. Other product packaging may display instructions explaining how to set up and use the product. Displaying important information regarding the product helps manage consumer expectations and promotes customer satisfaction. The better the buyer understands what they are purchasing, the more likely they are to be happy with said purchase. Still, other product packaging forgoes wordy instructions and simply lets the product speak for itself. Utilizing window box packaging or clear plastic boxes, the customer can properly view the product in real-time. Many prefer this over relying on drawn diagrams and written explanations. Being able to properly view the product for themselves can increase customer satisfaction and the likelihood of purchase.
