Abstract:
The quality of food, pharmaceutical, or sustainability products is generally maintained through optimal storage conditions or the use of packaging films. Herein, an intrinsically antibacterial and improvised polylactic acid-based film (hpp-PLA-film) has been produced by introducing a microwave-assisted synthesis process of carbon nanoparticles produced from hemp fibers (hf-CNPs). These high-performance packaging (hpp-PLA) films were produced with different percentages of loaded hf-CNPs, i.e., 0.05 and 0.5% (w/w), called hpp-PLA-0.05-film and hpp-PLA-0.5-film, respectively. The chemical entangling of hf-CNPs in PLA films was probed by various physicochemical, thermal, and mechanical characterization methods. The antibacterial properties of hpp-PLA-films could inhibit bacterial growth and outperform kanamycin, at least for longer time periods. Overall, it could be established that the produced hpp-PLA-0.05-film not only was better in mechanical, antibacterial, dissolution, and physical impact sustainability but also had biodegradation properties and may be a better alternative for regular PLA-based packaging composites in the near future.
