“…Chemical microbicides can be added to paper by directly coating or incorporation into cellulose pulp during the production process. Various types of antifungal agents such as azole antifungals [ 8 ], phenol derivatives [ 9 ], silver and zinc oxide composite [ 10 , 11 ], titanium dioxide [ 12 ], quaternary ammonium compounds [ 13 ], calcium propionate and parabens [ 1 , 3 , 14 ] have been reported to produce excellent antifungal activity. However, all existent antifungal methods have strengths and weaknesses: most of the methods mentioned above have potential toxicity to humans and the environment, which make them unsatisfactory for long-term usage [ 15 , 16 , 17 , 18 ].…”

Paper documents and products are very susceptible to microbial contamination and damage. Fungi are mainly responsible for those biodeterioration processes. Traditional microbicidal strategies constitute a serious health risk even when microbes are dead. Ideal methods should not be toxic to humans and should have no adverse effects on paper, but should own a broad spectrum, good chemical stability and low cost. In this work, we utilize an advanced antimicrobial strategy of surface stereochemistry by applying a coating of a shallow layer of polyborneolacrylate (PBA), resulting in the desired antifungal performance. The PBA-coated paper is challenged with the most common air-borne fungi growing on paper, Aspergillus niger and Penicillium sp. Ten percent by weight of the coating concentration or a 19-μm infiltration of PBA is sufficient to keep the paper spotless. The PBA coating also exhibits significant inhibition of spores’ germination. After PBA coating, both physicochemical properties (paper whiteness, pH, mechanical strength) and inking performance display only slight changes, which are acceptable for general utilization. This PBA coating method is nontoxic, rapid and cost-effective, thus demonstrating great potential for applications in paper products.

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.
