Properties of bioplastics as green packaging materials

Petroleum-based plastics have been widely used in packaging applications due to their strong mechanical strength and low-cost production, but they have raised several environmental concerns, such as plastic pollution and greenhouse gas emissions. Bioplastics have been introduced as sustainable alternatives to petroleum-based plastics due to their renewable sources and environmental friendliness. However, their performance is heavily dependent on their sources, modification methods, and compound compositions and formulations. Plus, their performance is limited by their mechanical, biological, and thermal properties, which will be a critical challenge for applications of bioplastics in green packaging materials.
This study will investigate the role of each bioplastic’s properties, which is how the bioplastic behaves under stress and forces for mechanical properties, how the environment will interact with the bioplastic, especially in terms of biodegradability and water absorption for biological properties, and how bioplastics behave when exposed to heat for thermal properties. This study provides valuable insights for researchers and manufacturers in developing high-performance, sustainable packaging materials by comparing the benefits and drawbacks of bioplastics to conventional plastics. It also contributes to efforts to reduce environmental pollution and dependence on petroleum-based plastics
