Abstract
Polyhydroxyalkanoates (PHAs) have emerged as promising biodegradable alternatives to petrochemical plastics for packaging applications, aligning with global sustainability goals. This study presents a comprehensive analysis of the scientific and technological landscape of PHA-based packaging from 1992 to 2024, combining a systematic review of 4176 scientific articles with a patent landscape analysis of 3328 patent families. The results reveal a robust increase in academic research since 2015, focusing on enhancing mechanical, barrier, and antimicrobial properties through nanomaterials and bioactive additives. Patent trends show a technological evolution from basic PHA formulations to multifunctional, smart packaging systems. The food sector dominates application areas, while blending PHAs with polymers such as PLA, starch, and PBAT remains a key strategy to improve performance and reduce costs. China leads in patent filings, driven by strong regulatory support, whereas Japan and the U.S. contribute significantly through industrial innovation. Despite the high potential of PHAs, challenges such as production cost, thermal sensitivity, and limited university-industry partnerships persist. The findings highlight the need for intensified collaboration and continued R&D investment to advance PHA-based packaging technologies toward large-scale adoption.
期刊介绍:
The aim of World Patent Information is to provide a worldwide forum for the exchange of information between people working professionally in the field of Industrial Property information and documentation and to promote the widest possible use of the associated literature. Regular features include: papers concerned with all aspects of Industrial Property information and documentation; new regulations pertinent to Industrial Property information and documentation; short reports on relevant meetings and conferences; bibliographies, together with book and literature reviews.
