Abstract

The increasing amount of synthetic plastic waste has contributed to environmental problems worldwide. As an alternative to synthetic plastics, thermoplastic starch (TPS) has been used for many applications, especially packaging application, since TPS provides good biodegradation and ease of disposal and reducing the consumption of petroleum. However, TPS tends to experience loss in mechanical properties and stability due to retrogradation of the starch. Modification of starch is often carried out to overcome this shortcoming in TPS. TPS can be made of various type of starch from various plant sources such as corn, cassava, rice, and potato. Sago starch is a plant-based starch that originates from the sago palm tree. The chapter aims to give a short literature overview on the sago starch, issues related to starch and thermoplastic starch, modification of sago starch via crosslinking method, properties of crosslinked sago starch, and limitation and opportunities of modification of sago starch via crosslinking method.
