BIODEGRADABLE MOLDED FOAM AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JPH05320401
Kind Code:
A
Abstract:
PURPOSE:To obtain a biodegradable molded having sufficient strength during use and storage by kneading a raw material comprising water and either wheat flour or starch, followed by baking. CONSTITUTION:A raw material which is a mixture of water and wheat flour and/or starch is kneaded and then baked and foamed to obtain the desired foam. The strength of the foam to be obtained can be improved by adding a reinforcement to the raw material. An improved foam strength can also be obtained by controlling the amount of the water so that the water content of the foam after baking is 3-20%. In particular, a molded foam containing a reinforcement and regulated to have a water content of 3-20%, preferably 3-15%, has further improved strength. The control of water content can be attained, for example, by leaving in a chamber for a certain time at a certain temp. or by spraying with water.
