A critical review on role of latex in bioplastics

Plastic, a synthetic material made from a wide range of polymers, has become an integral part of our everyday life. Due to their non-biodegradability and limited recyclability, they pose major environmental threats and waste management issues. Thus, an alternative to plastics is the need of the hour. While there are many alternate solutions in the form of bioplastics, many of them lack crucial properties like tensility, flexibility and stretchability to be able to completely replace plastics. Various additives and plasticizers are added to enhance their properties. Latex, a milky white colloidal substance, is one of the potential bio additives which not only elevates the strength of the blend but also enhances various properties including elasticity, hydrophobicity, and reduces water absorptivity. This study summarises the effect of latex on most common bio plastic bases including starch, cellulose, poly lactic acid and highlights the exploitation of the inherent elasticity of latex which has the potential to provide a plausible solution to the solid waste accumulation threat. This study also explores the future prospects of latex blended bioplastics and provides an insightful road map for further research.
