수출용 신규 망고봉지 원지 개발을 위한 국내외 상업용 과일봉지의 품질 평가

Abstract

In this study, we compared the qualities of overseas mango bags used in Southeast Asia and domestic fruit bags to induce the strategy of the development of export-grade mango bag base papers. Five types of overseas mango bags, three domestic pear bags, and the prototype base paper of mango bags manufactured by a Korean paper mill were collected. The collected fruit bags were separated into outer and inner base papers. Then, their basis weight, wet tensile strength, air permeability, opacity, light scattering coefficient and water repellency were measured. The outer and inner base papers of overseas and domestic fruit bags did not show significantly different basis weight. The wet tensile strength and air permeability of domestic pear bags and the prototype were not inferior to those of overseas mango bags, which confirmed that further improvement in these qualities was not required. However, since the prototype's opacity and light scattering coefficient were lower than those of overseas mango bags' outer and inner base papers, it was necessary to improve the prototype's light-blocking properties and water resistance. Therefore, it was concluded that the base papers' light-absorbing properties and water repellency should be effectively enhanced to develop export-grade mango bag base paper that could be used in Taiwan and Southeast Asia.
