Abstract
Water vapor permeability of plastic films was measured by Electric tester and Cup tester and the data of the two were compared. Regardless of the testing method, water vapor permeability measured by two methods showed consistent results. By these methods, water vapor permeability of polyethylene film was
플라스틱 필름의 투습도 측정장치를 제작하여 전자투습도 측정장치로 필름의 투습도를 측정해 본 결과 두 측정 장치간에는 5% 수준(P<0.05)에서 유의차가 없었다. 따라서 제작한 투습도 측정장치를 산업에 활용할 수 있을 것으로 판단되었다.
