Corrugated board provides packaging for most diverse industries with a share of over 50%, due to the numerous advantages they offer a good protection of the products. In other hand corrugated board fails in environmental conditions, indicating that relative humidity or temperature is higher. These effects directly damage the product packaged. To overcome on this problem recently corrugated boards produced with functional material, "functional corrugated boards," have become more available in the current market. A number of commercialized forms of functional material are coated or composited products with inorganic materials, for example "Nano clay" as representative. However, although the use of functional materials is increasing in corrugated boards, the several concerns such as over cost, environmental friendly materials, recycling, and toxicity affect consumer perceptions and acceptance. In the past, number of researcher focused on process of box compression and the utility of box compression testing etc., best of our knowledge there is no review paper which focus on the functional corrugated boards used in food packaging applications. This paper aims to review the availability of functional corrugated boards in the current market, past research studies on functional material and present the current status of functional corrugated boards in leading countries.

We studied the green synthesis and antibacterial activity of paper coated with chitosan-silver (Ag) green nanocomposites for packaging applications. Green synthesis of Ag nanoparticles (AgNPs) was achieved by a chemical reaction involving a mixture of chitosan-silver nitrate ($AgNO_3$) in an autoclave at 15 psi, $121^{\circ}C$, for 30 min. AgNPs and their formation in chitosan was confirmed by UV-Vis spectroscopy, transmission electron microscopy (TEM) and dynamic light scattering (DLS). As-prepared chitosan-AgNPs composite materials were coated on manila paper using Meyer rod. Surface morphology and Ag contents in coating layer were characterized by field emission scanning electron microscopy (FESEM) and energy dispersive spectroscopy (EDS). The mechanical properties such as tensile strength and elongation were significantly affected by coating with chitosan-AgNPs. The antibacterial test of coated paper was performed qualitatively and quantitatively against Escherichia coli (E. coli). It was shown to be effective in suppressing the growth of E. coli with increasing Ag contents on the surface of coated paper and more than 95 R (%) of antimicrobial rate was obtained at chitosan-AgNPs coated papers.

Purpose: The work aimed to integrate and distribute the knowledge of marketing and chemistry for product development, in which individual packaging from water hyacinth was ideal. Research design, data, and methodology: A customer perception was surveyed to guide the preparation process, and eco-packaging preparation followed the perception study. The satisfaction with the packaging using the 4Ps was determined. Results: 159 samples participated in the survey to establish their perceptions. They perceived that eco-packaging was a friendly environment with a score of 4.47. The uses of chemicals and water were less. The design for other functions than a normal function of packaging was preferred. The pulping was done using 3.0 M NaOH. The natural additives of carboxymethyl cellulose (defibering) and corn starch (adhesive) were desired. The paper was characterized according to The National Standard of Kraft paper and was equivalent to the liner board. The prototype of packaging was fabricated as individual packaging. The marketing mix was used to survey 200 samples. The satisfaction with the product was the maximum at 4.53, while the minimum was on price. The online channel was preferred to access the product. Conclusions: Water hyacinth could be added value as eco-packaging that the qualities of pulp were equal to the Kraft paper. Individual packaging from water hyacinth was satisfied.

The functions of food packaging are not only prevention from physical damage and loss during carrying and transportation, but also extension of shelf-life by adding antimicrobial substrate in packaging materials. Consumption of active packaging is gradually increasing. With different dosage of potassium sorbate(P.S.), the food preservative agent, antimicrobial papers were made by internal and external application of starch. The antimicrobial action of the paper was analyzed by the halo test and the shake flask method. The mechanical properties and strength were also measured. Antimicrobial papers adding P.S. showed higher values in tensile index than adding starch. The antimicrobial paper using starch showed similar microbe decreasing rate as that using P.S. Though microbe decreasing rate was 21.9%, it showed possibility to make antimicrobial paper using food preservative.

A novel antibacterial paper coated with chitosan-based silver (Ag) nanocomposite prepared by green synthesis has been investigated for a wide range of application in food, agricultural and medical packaging. Green synthesis of Ag nanoparticles (AgNPs) was carried out by a chemical reaction involving a mixture of chitosan-silver nitrate (AgNO3) in an autoclave at 15 psi, $121^{\circ}C$, for 15-120 sec. AgNPs and their formation in chitosan were confirmed by both UV-Vis spectroscopy and transmission electron microscope (TEM). Fourier transform infrared spectroscopy (FTIR) study showed that free amino groups in chitosan act as an effective reductant and AgNPs stabilizer. Antibacterial test of coated paper with as-prepared chitosan-AgNPs was performed qualitatively against E. coli based on the formation of halo zones around coated papers and it was shown to be effective in suppressing the growth of E. coli with increasing Ag contents in coating layer.

For both economic and ecological reasons corrugated box manufacturers are seeking to produce acceptably strong boxes while using more recycled paper. This study was to develop hydrophilic coating agents in order to improve overall physical properties of recycled corrugated fiberboard liners. Two coating agents were developed and applied to 'S' corrugating medium. The results showed that compression strength of new liners, named 'S-A' and 'S-B', were increased significantly both standard humidity and high humidity environment and it was as much as 'SK' liner. New developed liners were also economically advantageous since new liners were estimated about one hundred fifty dollars per ton cheaper than SK liner. The study indicated that further work is needed on the coating technology and machine development.

Objectives : The purpose of this report was to provide the information packaging of herbal medicines by analyzing papers. We investigated the packaging materials, packaging methods and expiration date of herbal medicines by analyzing papers of the Korea, Japan and China. Methods : We survey herbal medicine-related law and crude drug monograph of compendium in each three country, we purchased herbal medicine of the Korea, Japan and China in the market and verify the expressed-item in packing paper. In case of Japan, we examine packaging materials, packaging methods, and expiration date of herbal medicine in pharmaceutical company. Results : The pharmaceutical company in japan used the methods of nitrogen gas pouring, vacuum packing for the herbal medicine packaging. The expiration date of the herbal products in Japan is generally 3 to 5 year after packaging. And packaging materials were aluminium and polyethylene. In Korea, pharmaceutical company used airtight packing for the herbal medicine packaging and expiration date of the herbal product were generally 3 year after packaging. Packaging materials were polyethylene, nylon or polyethylene-nylon mixed materials. In China, pharmaceutical company also used airtight packing for the herbal medicine packaging, and the expiration date were generally 5 year after packaging. Packaging materials were polyethylene, wrapping paper-used parcel or tea leaves filter paper. Conclusion : This results can present the basic data for expiration date and preservation methods of the herbal roots in Korea.
