The packaging of fruits is very important because appropriate packaging can optimize the maintenance of freshness of fruits during their distribution in low or normal temperatures until the products reach consumers. The focus of this study was on the use of functional packaging materials for the post-harvest maintenance of the freshness of fruits. Oak charcoal has excellent far infrared emission and ethylene absorption qualities, and we developed a charcoal-processing packaging linerboard to evaluate the possibility for the use of charcoal as a functional packaging material for pears. Oriental pears of the Niitaka cultivar used in this study account for about 70% of pears harvested every year, and are a very popular domestic fruit in Korea. Pears packaged in packaging materials processed with charcoal were of significantly higher quality (p<0.05) than those packaged with conventional packaging materials, suggesting that charcoal-processed packaging materials can be used as functional packaging material for extending the storability and distribution time of fruits. Charcoal-coated linerboard was shown to be the most appropriate packaging material based on its compression strength, ethylene absorption performance, and the firmness and minimal weight loss of pears.

It is very important to foresee the main stream of technology development in the future. Packaging related manufacturers in equipment and materials focused their strength on products sharing big portion of world markets. As a result, domestic supply sources for packaging materials and equipment has been increased, but the manufacturer's capital and manpower is so limited to develop high technology machinery and high functional materials. The current status of packaging infrastructures in Korea is reviewed statistically. The hot issues in packaging arena are now in wafer level packaging, 3D packaging, and ultra-thin packaging. In addition, the recent advancement in microelectronics packaging technology is also covered.

Confectionary and food products were collected from Korea and Japan. Types of packaging structure, amount of packaging materials used, basis weight of paperboard, and product to packaging ratio were evaluated for understanding confectionery and food packaging in both countries. Also, new packaging samples were designed and fabricated for reducing the use of packaging resources and for optimizing the product to packaging ratio. Korean confectionary products showed much higher empty space inside package than that of Japanese products, while food products were not significantly different between tow countries. There were no significant differences in the basis weight of paperboard collected. All of the re-designed confectionary products showed more than 15% saving in packaging resource compared to current confectionary products.

In order to confirm European packaging waste statistics, this study was investigated annual variability of packaging waste generated, target of recovery and recycling rate for packaging waste and recycling rate of European countries based on Eurostat database. Eurostat is regional society statistics organization designated by European community to distribute development, production and European statistics. From 2005 to 2013, paper and paperboard packaging were generated the largest amount among the total amount of packaging waste generated during the period and the share of main packaging materials were generally constant among the packaging materials. In addition, European Union member countries have established target for the recycling rate and recycling rate for packaging waste which has been well maintained by most EU countries since the 2008 directive was enacted. The recycling rate for whole packaging waste such as glass, paper and paperboard, metal, plastic, wood continues to increase in Europe. In this study, Europe packaging waste statistics were organized and analyzed as yearly transformation of Europe packaging waste occurrence and disposal, recycling rate and recovery rate target value of Europe countries and recycling rate of each country in Europe base on centralized Eurostat database. Moreover GDP reduction were also confirmed due to trend changes and indirect impacts such as economic slump by packaging waste and recycling.

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.
