Packaging material needs to be packaged properly in order to protect it from contamination of other substances that can affect product quality. Moisture level of some products is high due to its moisture content and may result in the growth of Aspergillus niger fungus on the packaging. The use of thiabendazol in coating has been known as one of the methods to inhibit fungal growth on packaging. The purpose of this study is to determine the effect of coating on inhibition of fungal growth. Fungal resistance test was conducted by using Elmes method, disk diffusion and water absorption of packaging substrate (Cobb method). Carton as packaging material was coated using thiabendazol coating with various thicknesses (1μ, 2μ, 3μ, 4μ, 5μ and 6μ). Uncoated carton as control negative and nistatin as control positive. The optimal thickness of coating was 5μ with inhibition zone of 2.10 cm-21 mm. As thickness of coating increased, then the larger zone of inhibition produced. These results indicate that the resistance of the antifungal coating was getting stronger. Coatings contain thiabenzol can inhibit growth of fungal on the packaging.
