Abstract. The petroleum based plastics packaging has played an important economical and
practical advantages and made it well-suited for our daily lives, ranging for food packaging
applications until major component cover of most electronic devices. At present, however, the
world slowly becomes aware of the magnitude of conventional plastic waste due to its impact
on the environment. It is estimated that over 6,000 Million tons (Mt) of plastic waste has been
produced, while Indonesia is counted as the second country after China as the biggest plastic
waste producer. Another opportunity for the environment is the application of composite
bioplastics. In Europe, biodegradable plastics or simply referred as ‘bioplastics’ have remained
more or less in the research phase for several decades starting in 1990’s, but the European Union
(EU) has been actively supporting the development of these novel materials until 2024 and is
determined to support the growth of such industry due to its potential economy, social and a
fully sustainable and circular environmental benefit. Such bioplastics are made from at least
60% natural materials; mostly plant source-derived materials e.g. cassava starch, cellulose, or
seaweeds and can be degraded in the soil medium until one month. Nevertheless, bioplastics
have several disadvantages such as lower mechanical properties, bad thermal stability and
relatively low gas barrier properties or in other words high moisture absorption. This study was
intended to investigate the mechanical, thermal and gas barrier properties’ enhancement through
additional of nanocomposite derived from clay minerals. Finally, the product was examined
under Scanning Electron Microscope (SEM).
