Prepackaged food refers to the food that is packaged before being offered for sale. It is recognized with two important features. On one hand, its content cannot be altered without opening or changing the packaging. On the other hand, it can be directly consumed by ultimate customers. Prepackaged food plays a more and more important role in modern lives as it could bring many benefits, for example, it boasts more varieties, with longer shelf-lives, and is much more convenient for usage and storage. According to the report of “Research and Markets” (Hartman, 2015), the market of prepackaged food will bring $۳٫۰۳ trillion revenue by 2020. However, with the booming of prepackaged food industry, the food safety incidents increase accordingly, which greatly decrease the confidence of consumers and even bring about severe public health impact. Therefore, to prevent these food incidents and ensure a benign food consumption environment, a lot of efforts have been made by governments and industries. For example, the Food and Environmental Hyglene Department of Hong Kong has erected regulation on the labeling of prepackaged food to provide precise and sufficient information for customers. Wuliangye Yibin Co. Ltd, one of the most famous Chinese alcoholic beverage companies, has adopted radio-frequency identification (RFID) to the packaging of its products for anti-counterfeiting. The efforts are still far from sufficient that safety and quality problems still frequently happen, such as counterfeiting, excessive and unhealthy additives, and expired food and bad food. It is also challenging to solve these problems arising in prepackaged food industry as it involves too many companies, from raw material suppliers, producers, logistics companies, to distributers and retailers. Meanwhile, the amount of prepackaged food is tremendously huge, which posts another difficulty to control the quality. Furthermore, the packaging of the food is usually simple and cheap, which is easy to be fabricated. Effective tracking and tracing for these prepackaged food during their whole supply chains should be an effective tool to solve these problems, and it has also been widely recognized and verified in the food industry (Heyder et al., 2012; Gandino et al., 2007; Scholten and Verdouw, 2016). With the booming of Internet of Things (IoT) technologies, many Real-Time Tracking and Tracing Systems (RT3 Ss) for food supply chain have been developed to guarantee the safety of food (Trienekens et al., 2014). RT3 S makes it possible to detect potential safety threats and then make rapid response to deal with safety incidents (Aung and Chang, 2014). Besides, it can also increase the confidence of customers to buy these foods (Liu and Han, 2016).
