  • Packaging has been regarded as a environmental problem because of its relatively high portion of municipal solid wastes. Especially, cosmetic packaging has been focused because of characteristics of cosmetic packaging. Cosmetic products are highly sensitive products that pursue the beauty differently from other products. Cosmetic packaging materials are difficult to be recycled. Purpose of this study is to suggest the method to improve the environmental friendly packaging of cosmetic products. This study contains the major governmental policies on the cosmetic packaging in terms of environment issues in Korea, and suggested methods to develop the environmental friendly packaging of cosmetic products.

  • In order to obtain basic data on the shelf life of Epimedii Herba (EH), a physicochemical characteristics including weight loss rate, loss on drying, ash, acid-insoluble ash, and quantitative determination were evaluated to compare the data by packaging methods including general (G), general + silica gel (GS), alumium (AL), and alumium + silica gel (ALS) packaging and storage periods (0-66 months). All physicochemical analyzes were conducted using the method of "The Korean Pharmacopoeia (KP) 9th edition". As a result, weight loss rate (%), loss on drying (%), ash (%), acid-insoluble ash (%) of EH according to the packaging methods and storage periods were -0.27-4.73%, 3.06-9.35%, 5.48-7.37%, and 0.45-0.99, respectively. In the quantitative analysis of icariin, the marker compound of EH using high-performance liquid chromatography, the initial content was 0.44% at 0 month in all packaging methods. After that, the result of analyzing the content of icariin every 6 months was detected 0.44-1.18%. All of the above results satisfied the acceptance criteria for loss on drying, ash, acid-insoluble ash, and quantification contained in the KP. This study can be used as a basic data for establishing the packaging method and shelf life of EH.

  • Tape casting ceramics technology has been adopted for the fabrication of solid state electrochemical $CO_2$ sensors and the packaging substrates. The fabricated $CO_2$ sensors exhibit a fast response and a good recovery with the almost theoretical sensitivity of 37 mV/decade, corresponding to a sensor operating temperature of 373 K. The two packaging methods, the wire bonding package and the surface- mounted on the ceramic package, were compared with respect to their power consumption and mass production feasibility. In terms of the ease of fabrication, the surface mount packaging technology is superior to the wire bonding technology but its power consumption is approximately twice that of the wired package.

  • In this work, source reduction of poly ethylene terephthalate (PET) packaging are discussed as aspect of sustainability, such as reuse, refill and recycling through the various treatment methods and historical studies for municipal solid waste (MSW) disposal. Since PET has good chemical, physical and mechanical properties, and provides good oxygen and carbon dioxide barrier properties, PET is one of the most widely used thermoplastic polyester in the U.S. and around the world. As the demand for non-renewable PET is increasing, several approaches have been developed to meet economical feasibility and environmental responsibility without degrading material performance. Several companies, such as Coca-Cola Co., Easterform Packaging Co. and Kraft, have tried to develop lightweight PET bottle, and some of lightweight PET bottles are already commercialized. Reuse and refilling for PET container is well developed in Europe, such as Denmark, German and Netherland by supportive legislation and policies. Recycling process is the best way to economically reduce PET waste. In consequence, advanced technique and further development must be provided due to increasing PET packaging waste.

  • In this study, we aimed to evaluate the quality of Aralia elata shoots according to different packaging methods during storage at 2℃. The highest level of dehydration and wilting incidences were observed in polypropylene containers with polyvinyl chloride wrap (PP+PVC), and these levels continually increased during the entire storage period, compared to other packaging methods. The overall marketability of A. elata shoot packaged in polyethylene terephthalate container (PET) and PP with the mineral-coted functional warp (PP+F) constantly declined during storage with a similar level of 38.6 and 36.0% at 15 days in storage, respectively. PP with PET cover packaging (PP+PET) showed the lowest decay and wilting rates during the entire storage, and the wilting score at 10th day was 51.9, 58.0, 51.8% suppressed, as compared to PET, PP+PVC, and PP+F, respectively. Consequently PP+PET packaging effectively decreased the deterioration of A. elata and maintained marketability for 10 days of storage at 2℃.

  • The effect of packaging methods on the quality of stick type restructured jerky was investigated in terms of pH, water activity $(A_w)$, TBA (thiobarbituric acid) value, total bacterial counts, and sensory evaluation during storage at room temperature $(25^{\circ}C)$ for 90 days. The jerky was subjected to plastic or vacuum packaging at $(25^{\circ}C)$. The pH decreased slightly as storage time increased (p<0.05), but there were no significant differences between the packaging methods. The water activity of jerky in plastic packaging decreased as storage time increased (p<0.05), however jerky in vacuum packaging showed no significant change. Vacuum packaging resulted in a higher water activity value than plastic packaging. The TBA and hardness values decreased as storage time increased (p<0.05), and there were significant differences between packaging methods during the storage period (p<0.05). The total bacterial counts in vacuum packaged jerky were lower than jerky in plastic packaging. The sensory evaluation of each treatment decreased slightly as storage time increased (p<0.05), however there was no significant difference between packaging methods. Based on our findings, we conclude that vacuum packaging provides more effective storage than common packaging of jerky.

  • Whit trade increasingly taking place on the global stale, packaging becomes even more important However, there is only a fine line between the balance of waste created by damaged goods and waste created by over-packaging. A vast quantity of material is used by the packaging industry for the reason of bringing products safely to the customers. In this research I gathered 87 samples of various kinds of confectionery to analyse the actual conditions of the appropriate packaging. As a result, the rate of the needless space excluding actual contents comes to over 60% which clearly says that the most products are over-packaged. Despite assertions from the packaging industry that all packaging is necessary in reducing product waste, the research shows us the fact that it's over-packaged. What needs to be questioned, here, is the level of materials we use in packaging our products, and how we can continue to decrease that amount and recycle what we do use. In the future where materials and resources become more scarce, and therefore more expensive, and the methods of disposal become more costly and accountable, designers and manufacturers constantly need rethink and improve methods of packaging.
