In addition, damage to health and ecosystems by remaining in the environment for a long time, is a relevant issue of immediate attention.

It was observed while in presence of stress parameters, the plants showed stunted growth, degraded chlorophyll and little to no yield, the PPGPB treated stress setups showed remarkable improvements in vegetative, biochemical as well as reproduction.

Food packaging has become an important aspect of supply chain management that not only governs the food from spoilage but also contributes to a sensible biocompatible material, safe for human consumption as there is a recent concern on microplastic leaching. Polyhydroxyalkanoates (PHAs), derived from microorganisms, are extensively used as a polymeric base for packaging applications in food industries as they offer advantages such as biodegradability, non-toxicity, hydrophobicity, thermoplasticity, and superior barrier properties, thereby making them a promising alternative to conventional synthetic plastics. However, challenges related to material properties, performance, and cost of the product must be addressed for PHA to make it an economical and feasible packaging material. Recent developments in PHA formulations in terms of technology, additives, and production factors have led to improvement in the polymer properties and beaconed the advent of active packaging. PHA-based packaging systems can redefine food industry packaging, turning it from a passive physical entity into an active solution that sustainably ensures food quality and safety.
