기초 화장품 패키지의 PCR 용기 적용 효과에 관한 연구

초록

Background The carbon-neutral era has led to a high potential evaluation of the post-consumer recycled plastic (PCR) market. However, due to the lack of awareness about waste plastics and skepticism about their quality and stability, the utilization of PCR plastics in the cosmetics industry is relatively low. In response, this study aims to compare the color, surface phenomena, and printability of pure polypropylene (PP) and PCR PP in cosmetic containers through injection molding experiments. Methods First, the data used in this study was collected through related literature, policy repots, and newspaper articles. Second, design phenomena were compared and analyzed through a container injection experiment. Third, based on the results of the experiment, an offline survey was conducted by dividing respondents into the general public and expert group, and the results were analyzed by chisquared test and independent sample t-test. Results The results of the PCR injection experiment were divided into color, surface state, and printability and compared and analyzed with pure PP. As a result, in the case of color, PCR PP showed a lower chroma than pure PP, and black spots intermittently appeared on the PCR PP surface. In the case of printability, there was no difference between the two materials. According to the survey on 'The development of cosmetics containers of natural ingredients,' based on the experimental results, most survey respondents preferred PCR containers and found no dark spots. In the case of purchase intention, the group that did not find dark spots, showed high purchase intention. However, there was no statistically significant difference. Conclusions In this study, PCR PP was preferred over pure PP in the development of natural ingredient-based basic cosmetics. The subtle low-chroma coloration that appears during PCR PP injection molding was found to be a significant conclusion that can convey an eco-friendly image. The significance of this paper lies in the fact that the design phenomena were analyzed through experiments conducted under the same conditions for both materials, following actual processes. There is a need for further research on the use of PCR plastics in color cosmetics containers and the various plastic materials related to PCR plastics. © This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License
