Synthesis of Biodegradable Polymer-Based on Starch for Packaging Films: A Review

Abstract

Due to their crucial qualities and functionalities, polymers have received a lot of attention in recent years as food packaging materials. These characteristics include non-toxicity, ease of availability, biocompatibility, and biodegradability, showing their promise as an alternative to traditional plastic packaging, which has long been under investigation for its environmental impact. Given the present emphasis on sustainable development, research into biopolymers as eco-friendly and sustainable food packaging materials is critical. The synthesis of biodegradable polymers-based on starch represents a significant stride towards sustainable packaging solutions. As the global demand for eco-friendly materials continues to grow, ongoing research and innovation in this field are poised to lead to the development of starch-based packaging films with improved properties and widespread commercial applications. As a result, the primary goal of this review is to create a biodegradable polymer based on corn-starch and PVA with strong physicomechanical characteristics for usage in plastic bags.

Overview of biodegradable polymers: synthesis, modification and application

“…Authors [46] examined the impact of PVA molecular weight on the biodegradable properties of PVA/starch blends by blending PVAs of different molecular weights with varying compositions of cross-linked starch (CLS). A PVA exhibiting superior biodegradability was identified from the PVA/starch blends with higher biodegradability.…”
