**2. Food packaging science and emerging trends**

Food packaging incorporates a wide range of technological activities, including design, package fabrication, shelf-life testing, distribution, and marketing. Food packaging science is a discipline that applies the perfect blend of four pioneer science areas: materials science, food science, information science, and socioeconomics in order to understand the requirements of any packaging system [9]. Material science and food science have been the two major guiding principles in the development of food packaging. Material science is essential to comprehend the appearance, mechanical strength, barrier, and physical and chemical properties of any substance used [10]. Food science is concerned with the kinetics of food deterioration and governing its shelf-life. Food packaging technology is a science-based solution to specific food packaging needs; examples include tamper-proof packaging, microwavable packaging, and modified atmospheric packaging, all of which aim to improve consumer safety, quality, and convenience [11]. The primary goal of the field of information science is to examine consumer attitudes and behaviors toward food packaging, and then analyze the results to determine what the most important features of packaging are for consumers, which are comfort for use and durability [12]. In regard to socioeconomic needs, the very distinguished ones are lifestyle changes, in a way that reflects the quality of life through the added value offered to consumers through packaged products, profitable companies, packaged product safety, and environmental protection [13].
