Bio coating as an alternate for wax coating for food grade paper boards

1.45 million tons of paraffin wax-coated boxes of used products enter landfills every year, and 4.5 million metric tons of carbon dioxide is released during the recycling process. Therefore, the goal of the research is to find out an alternative to the synthetic wax coating seen on food product cartons. This research uses natural coating materials that are more effective than synthetic coating materials, such as hibiscus, gum Arabic, and turmeric. The natural antibacterial herb turmeric's curcumin is extracted using ethonal, and then heating is used to create the hibiscus extract. Three layers are coated on the package: the first layer is curcumin, which serves as the package's antimicrobial coating; the second layer is gum Arabic, which serves as a binder to hold the third layer of hibiscus. These two layers serve as a barrier on the packaging, and then the hibiscus extract gel is applied over them. Using a spray gun, these three coats are applied to the packaging. The method used to dry the coatings is air or sun drying. The test findings are assessed for the burst strength, burst factor, moisture content, smoothness, calliper thickness, and micropsoic analyses of the wax coated and bio coated carton samples.
