The growing world population, evolving urbanization, and globalization have created more demand for food, which has increased challenges in food safety. Development and innovations in food packaging, one of the most important components in the food industry, is of key importance as food safety issues have gathered tremendous attention of the world. Food packaging is mainly intended to prevent a deterioration in quality of foods and beverages during distribution, sales, and consumption. Polymeric materials have been widely used as packaging materials due to their advantageous characteristics, including excellent mechanical, thermal, and corrosion-resistant properties, a lightweight nature, and ease in production. Polymer composites refer to polymers impregnated with nanomaterials and organic or inorganic compounds. Polymer composites have been applied in the packaging industry to enhance or bestow additional properties to packaging materials. This review summarizes the recent advances in polymer and polymer composites used in food packaging applications. First, progress in the polymers utilized for food packaging, with a focus on biodegradable polymers, will be introduced. Subsequently, the utilities of polymer composites in advanced food packaging will be highlighted and categorized into three classifications of packaging: improved, active, and intelligent packaging. Next, concerns on the relevant safety issues and regulations will be briefly discussed. Finally, an outlook on the future research directions of polymer and polymer composites for food packaging will be provided. 相似文献

Even though research on nanotechnology has increased rapidly in the last decades, the application of nanotechnology in food and beverage packaging started to show an interest in the scientific community much more recently. Food safety, quality and improvements of properties compared with conventional materials make nanomaterials very attractive in the field of food and beverage packaging applications. Furthermore, in many cases, nanomaterials are used for both food packaging and the food contained, especially when we talk about nanomaterials for active and intelligent packaging. Oxygen scavengers, antimicrobial nanomaterials and nanobiosensors are some examples of current research efforts on nanomaterials for food packaging. This fact has led to a variety of nanoparticles and nanomaterials. The wide range of existing nanomaterials could make its selection for food packaging applications a challenge. Thus, building up a map based on the current state‐of‐the‐art nanoparticles and nanomaterials is required. Furthermore, there is a need to classify all the nanomaterials used specifically in food packaging, independently of their nature, the packaging material and the way they are integrated to this material. In this paper, a classification of the latest advances in this field was made accompanied by the use of Multi‐Criteria Decision Analysis in order to find which are the most relevant (and/or expected to be potentially exploited in the near future) nanomaterials in the area of food packaging.
