  • Active packaging is one of the innovative concepts which actively change the condition of the packaged products. Active packaging technique controls the environment inside the packaging in order to extend the shelf life of the product and improve its quality or safety. Active packaging are based on major contents of scavenging concepts, releasing concepts, and other active packaging concepts such as removal or indicating systems. In recent years, experimental developments using active packaging concepts between polymeric packaging materials and the contact surfaces of food products are widely studied in order to make extensive commercial applications. Well-developed packaging markets in USA, Japan, and Europe are already being successfully applied in active packaging concepts. This paper reviews the concepts of active packaging and current information of active packaging technologies. The status of domestic technologies in active packaging were analyzed.

  • Today, the food packaging industry has a great interest in using active packaging to fresh food product as a solution for the future to positively provide its quality, safety and shelf life. Many researches have extensively studied functional packaging strategies in recently years. Controlled release packaging (CRP) is an innovative packaging technology in the packaging polymer matrix from which can active agents are delivered in a controlled way into the product. CRP technology is well-suited for controlling release of antimicrobial compounds and antioxidants to prevent food degradation reactions such as microbial growth and lipid oxidation. Advances in CRP technology allow food packaging manufacturers to challenge the development of better functional food packaging systems. This overview examines the most recent developments and technologies of active packaging for applying the food industry. The scope of this article has mainly been focused on controlled releasing systems.

  • The effects of active packaging on the surface stiffness, mass, volume, density and weight changes of fresh as well as stored eggplant were studied at 11 and $25^{\circ}C$ for 10 days with active packaging material Type 1 and 2 and control. Mass, volume, and surface stiffness of eggplant decreased linearly throughout the storage period regardless of storage conditions; while the mass density showed a reverse trend in the ease of $11^{\circ}C$ storage. Reduction rate of mass, mass density and weight was observed minimum at $25^{\circ}C$ storage temperature with active packaging Type 1. The weight of eggplant decreased at a higher rate in the initial 4 days compared to that in the later period of storage regardless of storage temperature and type of packaging.

  • Due to the increasing consumer demands for the safety, shelf life, and quality of food, the application and development of active packaging in the food and packaging industry have been improved. According to the standards and specifications of the Republic of Korea for utensils, containers, and packages, the function of active packaging is to remove or alleviate factors that degrade food quality. Although extensive reviews regarding the development and commercialization of active packaging have been conducted, the legal regulations and safety assessments concerning active packaging have rarely been examined. This review provides information regarding the definition, structure, components, operational mechanisms, and applications for active packaging that actively removes oxygen, moisture, carbon dioxide, and ethylene. Furthermore, the legal regulations and research results related to the development of test methods for safety assessments of active packaging are investigated.

  • This paper provides an overview of kimchi packaging technology, focusing on packaging materials, package design, and active/intelligent packaging technology for kimchi. From a packaging-material standpoint, although various materials have been used to ensure customer satisfaction and convenience, plastic is the most widely used material, in the form of bags, trays, pouches, and rigid containers. Additionally, recent efforts in the kimchi packaging industry have allowed companies to differentiate their products by using different packaging materials and technologies, while simultaneously improving product safety and quality. On the other hand, the biggest problem in kimchi packaging is excess $CO_2$ production, leading to package expansion and leakage. To alleviate this problem, the use of $CO_2$ absorbers, high $CO_2$-permeable films, and degassing valves, in addition to the use of different packaging systems, has been investigated. Active and/or intelligent packaging systems have been developed, to include active functions beyond simply inert, passive containment and protection of the kimchi product. However, most such approaches are not yet adequately effective to be useful on a commercial scale. Therefore, further studies are needed to resolve the limitations of each technology.

  • Nanocomposite has been considered as an emerging technology in developing a novel food packaging materials. Polymer nanocomposites exhibit markedly improved packaging properties due to their nanometer size dispersion. These improvements include increased barrier properties pertaining to gases such as oxygen, carbon dioxide, and water vapor, as well as to UV rays, and increased mechanical properties such as strength, stiffness, dimensional stability, and heat resistance. Additionally, biologically active ingredients can be added to impart the desired functional properties to the resulting packaging materials. New packaging materials created with this technology demonstrate an increased shelf life with maintaining high quality of the product. Nanotechnology offers big benefits for packaging. Nanocomposite technology paves the way for packaging innovation in the flexible and rigid packaging applications, offering enhanced properties such as greater barrier protection, increased shelf life and lighter-weight materials.

  • Concerns on environmental waste problems caused by non-biodegradable petrochemical-based plastic packaging materials as well as consumer's demand for high quality food products has caused an increasing interest in developing biodegradable packaging materials using annually renewable natural biopolymers such as polysaccharides and proteins. However, inherent shortcomings of natural polymer-based packaging materials such as low mechanical properties and low water resistance are causing a major limitation for their industrial use. By the way, recent advent of nanocomposite technology rekindled interests on the use of natural biopolymers in the food packaging application. Polymer nanocomposites, especially natural biopolymer-layered silicate nanocomposites, exhibit markedly improved packaging properties due to their nanometer size dispersion. These improvements include increased mechanical strength, decreased gas permeability, and increased water resistance. Additionally, biologically active ingredients can be added to impart the desired functional properties to the resulting packaging materials. Consequently, natural biopolymer-based nanocomposite packaging materials with bio-functional properties have huge potential for application in the active food packaging industry. In this review, recent advances in the preparation and characterization of natural biopolymer-based nanocomposite films, and their potential use in food packaging applications are addressed.
