Starch-Based Foamed Materials—Use and Degradation Properties

Abstract

Many discussions on packaging lead to undue expectations regarding the usability of degradable materials. There is also considerable misuse of the term “biodegradable.” The manufacture of a new foamed material based on native starch is discussed. The structure forms by water evaporation and gelatinization of starch during a molding and heating step. Typical applications are shown. Composting tests confirm degradation within a few weeks without the accumulation of residues.
