The present application relates to a polymer material and a use thereof. The present application can provide a polymer material having both excellent biodegradability and absorptivity by using a polysaccharide component capable of efficient cross-linking while using no cross-linking agent that can adversely affect biodegradability, or using the relevant component to the minimum. The present application can also provide a use of the polymer material.

A starch slurry includes a starch in an amount of approximately 25 to 91 weight percent, a plasticizer in an amount of approximately 3 to 30 weight percent, water in an amount of approximately 5 to 60 weight percent, and a blowing agent in an amount of approximately 1 to 30 weight percent. The starch slurry can have a bulk density of between approximately 10 to 100 pounds per cubic foot. The blowing agent may include sodium bicarbonate. The starch slurry can be used for generating foamed products or printing a starch foam.
