Strength Properties of Coated Paper with Cuminum cyminum L. and Prunus mahaleb L.

Abstract

Coating of the papersurface against to microorganism to making it suitable for food packaging iscrucial in terms of improving antimicrobial properties. Cuminum cyminum L. known as cumin and Prunus mahaleb L. have the abundant chemical compound. Cumin hasantiviral activity that making it proper for coating due to its variouscomponents. Mahaleb as well has rich fragrance make it eligible for sugarysnacks and chocolate package. After coating with such biomaterials, thanks tovaried fatty acids impart protective feature from oxidation to paper surface.It was observed that the odor of substances was trapped from paper samples.Wrapping paper selected as a base paper in this study. Cationic starch used foremulsifying the coating chemical. Cumin and mahaleb added the starch emulsionand coating suspension applied on the top pile of the paper with # 0 drawdownbar. Coating application reduced the paper's tear index results but increasetensile and burst index results in both cases. Mahaleb gives better Cobb60value and bursting and tensile index and comparing to Cumin. However, cumincoated papers tensile index results in machine direction was better thanmahaleb. Both natural substances are suitable material as an additive to thecoating.
