With the continuous progress and development of the social economy, the importance of commodity packaging is increasingly manifested. It has become an important form of communication between businesses and consumers, and an important means of competition between businesses. The research scope of the thesis: First, through literature investigation, analyze the function of packaging design and consumers' buying attitude, and analyze the name, color, logo, illustration, etc. for general chocolate packaging and travel souvenir chocolate packaging. Research method: Through questionnaire survey, according to consumers' purchasing attitude and personal value of package design, we have in-depth understanding of consumers' purchasing power and package design's influence on purchasing conditions and research. According to the results of this study, first, from the perspective of general chocolate packaging and travel souvenir chocolate packaging to consumer consumption phenomena, general chocolate is more popular. Second, when consumers buy products, the taste of chocolate is more important than product packaging design. Third, in each product group, consumers value their own value when buying chocolate products. Fourth, due to the two important attributes of packaging design and taste, ordinary chocolate has a higher purchase intention than travel souvenir chocolate.

Due to the rise of customer's alertness about fresh foods to health, in the past few years, the consumption of fresh food has increased sturdily. The use of gas scavengers is the most appropriate packaging technologies for fresh, fresh-cut produces and in ready to eat products. The gas absorber/scavenger has ability to protect or stabilize the wanted properties and shelf life of food. The success of gas absorbers in food depends on many parameters such as types of foods, storage temperature, relative humidity, initial gas concentration, and the characteristics of package materials. In this review article, we focus on the most recent research trends in gas scavenging systems used in food packaging, future trends. Intense research from industry and engineers remains important to the development of gas scavenging package that fulfill consumer requirements, enhance product quality, and offer environmentally friendly design and cost-effective application.

본 논문에서는 Mega-Function System Integration을 추구하는 SOP기술의 필요성과 10가지 요소기술에 대하여 개략적으로 언급하였고, SOP 기술은 SOC, SIP 및 기타 부품 집적기술과는 경쟁관계가 아닌 융합 발전할 수 있는 기술이 라는 점을 강조하였다. 또한, System Level Integration 을 위한 SOP 요소기술들은 단순히 부품 혹은 Module level에 필요한Design, 공정, 재료기술만이 아니라, System의 전반적인 차원에서 분석, 해결되어야 하는 것을 알 수 있겠다. 따라서, 이제는 모든 요소기술을 종합적, 유기적으로 개발할 수 있는 연구개발전략이 매우 중요한 과제이다.

Sorption studies involving the sorption of n-propanol by an Amorphous Nylon(Nylon 6I/6T) were carried out as a function of sorbate vapor activity at $23^{\circ}C$. Vapor activity levels from 0.035 to 0.91 were investigated to evaluate the concentration dependency of sorption mechanism. Sorption behavior of propanol by Nylon 6I/6T showed distinctive two mode sorption phenomena as a function of Vapor activity. At Vapor activity levels below a=0.11, equilibrium sorption was achieved within a short period of time(less than 20hrs), which can be interpreted as following a Fickian diffusion model. A Langmuir-Flory-Muggins Dual Mode Sorption model can also be applied at these concentration levels. However, for Vapor activities above a=0.11, the sorption process appeared to be non-Fickian and resulted in a lack of equilibrium being attained.

We studied the consumer preference for the packaging of "Samgyetang" retort product in order to improve its function and design. A total of 319 eligible respondents (male 175, female 144) were surveyed with a questionnaire asking on the general characteristics for the preference of the packaging function, type of retort package, packaging design, convenience, cooking method of retort product and characteristics of "Samgyetang" retort product. The collected data was analyzed using a chi-square (X²) statistical test in SPSS program. The results showed that the retort packages with opacity and microwaveable types were preferred. Also, most respondents expressed that it needs to be improved for cooking convenience. Another question results showed that the consumers are considering the taste and cost of a product more important than the brand of its product when purchasing. Based on the results of the questionnaire, the study suggested that many consumers want the convenience of packaging and product protection for high value added product. The results help to provide consumer's demand for packaging development and to provide the greatest advantages in terms of production and marketability of "Samgyetang" retort product.

The demands for Home Meal Replacement (HMR) products are continuously increasing owing to the convenience of instant food and online food delivery. Ready-to-heat (RTH) products have received massive attention in the HMR industry because these products can be easily warmed using a microwave oven. However, the conventional microwave packaging should be opened before microwave heating to prevent bursting or food loss owing to the steam-pressure build-up inside the package. Open packaging might lead to non-uniform food heating and cross-contamination. Therefore, packaging materials that are able to release steam without opening are of interest to the HMR industry. In this study, polylactic acid(PLA)/polyethylene glycol(PEG)/nanoclay composite films were manufactured using an extrusion method as packaging materials with a smart steam-releasing function. The introduction of PEG to the PLA imparted a steam self-releasing feature to the composite films owing to the morphology change of composite films during microwave heating. Further, PEG increased the ductility of PLA, which in turn prevented bursting caused due to the steam-pressure build-up. The uniform dispersion of nanoclay obtained by a twin-screw extrusion led to stronger mechanical properties. Therefore, the smart composite films developed here can be applied as microwave packaging materials with a self-releasing function.

As one of traditional packaging materials, paper and paperboard are being more popular and beneficial thanks to their environmental sustainability and have been widely used in packaging applications, from light weight infusible tissue for tea/coffee bags to heavy duty boards for the distribution. Papermakers have to design the products having a desired customized function with their paper machine. Globally, the use of filler and pigment in papermaking is now a very common practice to meet the needs of customers. Many benefits can be achieved as a result of filler addition, which mainly includes cost and energy savings. The replacement of traditional mineral fillers and pigments with biodegradable and renewable carbohydrate polymers is a very interesting and promising research topic due to the concern of environmental impact. In this review paper, the use of traditional and novel carbohydrate fillers and pigments in cellulosic paper is highlighted. It is noteworthy that there are still some challenges and technical barriers associated with the use of these organic materials in point of structural stabilities and manufacturing costs, although most of them are available in market as the commercialized products. With the emerging nanotechnologies, it is believed that the use of carbohydrate-based filler and pigment for papermaking will increase and bring technical advantages to industry.
