Superior Ductile and Barrier PLA/PGA Films by an In Situ Constructing Transversely Isotropic Network and Well-Ordered Crystalline Nanolayers

Macromolecules, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 9, 2025

Simultaneously achieving excellent toughness, transparency, and gas barrier properties is still a challenge for poly(lactic acid) (PLA) films. In this work, we address an effective scalable strategy based on biaxial stretching to make superior ductile, transparent, high-barrier PLA films by incorporating polyglycolic acid (PGA) constructing transversely isotropic structure in the matrix with numerous nanocrystals nanolayer PGA phase. The endowed PLA/PGA robust chain entanglement network, which prevents formation of densely distributed cohesional physical aging PLA, allowing molecular chains move sufficiently exhibit toughness. Consequently, tensile strength film increased from 67 157 MPa while maintaining high elongation at break (>100%), transparency (>85%), durability, demonstrating comprehensive mechanical properties. Importantly, situ constructed phase greatly prolongs diffusion path molecules films, consequently oxygen permeability coefficient (PO2) decreased almost two orders magnitude, i.e., 1.66 × 10–14 7.10 10–16 cm3·cm/cm2·s·Pa, compared that neat three magnitude lower than polyethylene film. Therefore, work contributes deeper understanding structure–property relationship biaxially oriented PLA-based may enable their application green packaging field.

Agro-Food Waste Valorization for Sustainable Bio-Based Packaging

Journal of Composites Science, Journal Year: 2024, Volume and Issue: 8(2), P. 41 - 41

Published: Jan. 24, 2024

In recent years, the increase in generation of agro-food processing waste, coupled with uncontrolled disposal and inefficient recovery methods, has raised concerns among society, industries, research community. This issue is compounded by accumulation conventional synthetic packaging. Owing to their significant environmental economic impacts, development sustainable, biocompatible, biodegradable materials become an urgent target. this context, efforts have been directed toward developing new packaging based on renewable sources, such as contributing circular economy concept. However, despite advances, novel agro-food-waste-based solutions still largely remain at a laboratory scale. situation highlights need for further understanding thorough investigation into how upscale these products, thereby promoting engagement, investment, awareness across various fields. review aims discuss current advances food using waste. It covers main wastes by-products currently recovered sustainable systems through approaches, extraction valuable compounds or waste treatments incorporation materials, techniques valorization, applications films coatings. also addresses toxicological safety challenges, future perspectives. After extensive review, we conclude that faces challenges transitioning findings commercial scale, primarily due factors, high production costs, performance deficits, legislative ambiguities, lack consumer awareness, inadequate governmental regulations. Consequently, investments appear be mandatory coming aiming optimized, safe, cost-effective solutions.
