Study on the Preparation and Mechanical Properties of Starch/Fiber Cushioning Packaging Materials

Abstract:

In order to minimize the environmental pollution attributed by traditional plastic packaging material with cushioning performance, a new biodegradable packaging material with cushioning performance was created in the present research. Being made from potato starch, fiber and PVA as well as foaming agent the new product was prepared by a measure of pressure-molding. The impact of each of the four components on the mechanical properties of the product was studied and the optimal formula was determined by a measure of orthogonal test. The results showed that a formula of potato starch 100g, fiber 30g, PVA 40gand foaming agent AC 0.80g gave the product the better mechanical property where tensile strength reached 1.93MPa. Comparing with traditional foamed plastic packaging materials the extension strength of starch-fiber based new product showed 60%-180% higher than EPS’s and 50%-150%higher than EPE’s.
