New biodegradable coating for disposable tableware

The country's use of degradable disposable tableware is made of paper fiber, straw, and edible starch made of tableware, and then coated with water- and oil-repellent coating on the surface. The coatings available on the market today are non-degradable polymer coatings. The surface of this tableware is still a source of white pollution. Prof. Tian Bingshou from Wuhan University and Yang Yuanli and Gao Gong cooperated to thoroughly eliminate the white pollution caused by the waterproof and oil-repellent layer of this type of tableware, and conducted hundreds of trials on a variety of formulations, processing techniques and coating applications. Edible oil is a modified biodegradable coating.

Broad source of raw materials, low price; modified to low temperature, pressure, no emissions, low energy consumption; the coating is a water-based white emulsion, non-toxic, harmless, no odor; strong adhesion, good film formation, can be Brush coating, shower coating, spray coating; storage for more than six months invariability, not deteriorating, if thickened can be added to adjust the viscosity to the desired viscosity, the same performance; residual paint on the coating is easy to clean and remove water; after coating 130-160 °C temperature bake for 4-5 minutes, no toxic gas emissions during the drying process. The foamed straw fiber tableware was tested by Wuhan Quality Inspection Institute and Wuhan University Test Center and fully met the technical specifications specified in GB18001.6. The use of paper fiber - edible powder-type dishes has also been satisfactory. Tableware is not discolored, undamaged, and invariable under storage conditions. Its characteristics: After biodegradation of soil, it can be used as fertilizer and it can promote the growth of plants. The water enters into disintegration and degradation with the tableware.

The biodegradable coating provides an indispensable product for real full-degradable disposable tableware, and will replace the non-degradable synthetic polymer coating, and has a promising market prospect. Welcome people of insight to participate in cooperative production, as soon as possible to bring the product to market.
