Poly (Lactic Acid)/Starch Biodegradable Blend With Antioxidant Activity: A Sustainable Alternative for Single‐Use Active Plastic Packaging

Journal of Applied Polymer Science, Journal Year: 2025, Volume and Issue: unknown

Published: March 3, 2025

ABSTRACT A novel bio‐based and biodegradable plastic based on poly(lactic acid) (PLA) corn starch (CS) was developed as a single‐use rigid packaging material. Chitosan (Q) eucalyptus essential oil (EEO) were incorporated antimicrobial antioxidant agents. The effects of these additives evaluated using three‐factor, two‐level factorial design, assessing the melt flow index (MFI) tensile properties. optimized formulation, containing 5 wt% EEO 3 Q, increased thermal stability CS due to PLA matrix with two degradation steps: 145°C 318°C. It also demonstrated low water interaction, solubility approximately 0.6% moisture content 5%, attributed absence plasticizers. Additionally, material achieved nearly 70% activity through synergistic effect Q. Successful thermoforming trials confirmed processability formulation. Comparative analysis polypropylene revealed that exhibited higher strength while offering critical advantage biodegradability. These findings highlight potential this active, thermoformable sustainable alternative conventional non‐biodegradable plastics.

Poly(Butylene Adipate‐Co‐Terephthalate)/Silane‐Treated Wollastonite‐Based Blown Film for Sustainable Packaging Application: Studying the Impact of Uniaxial Stretching on the Final Properties

Macromolecular Materials and Engineering, Journal Year: 2025, Volume and Issue: unknown

Published: April 7, 2025

Abstract The demand for biodegradable packaging is rising due to plastic pollution corncerns. This study develops composites based on poly (butylene adipate‐co‐terephthalate) (PBAT) and silane‐treated wollastonite (S‐W) at two concentrations (15 25 wt%) through a combination of melt extrusion blow‐film techniques. Next, the PBAT/S‐W composite films underwent uniaxial stretching in machine direction (MD) effects their morphology, mechanical thermal properties, barrier performance, contact angle, X‐ray diffraction (XRD) different stretch ratios (SR). incorporation S‐W 15 wt% increased achieving ≈500% tensile strength 1000% Young's modulus SR6. Thermal XRD analyses demonstrated that significantly enhanced film crystallinity because strain‐induced crystallization. Morphological analysis indicated opposing high SR: pronounced alignment molecular chains MD weak adhesion between filler polymer matrix, which can impact material's structural integrity. water vapor properties PBAT/S‐W25% blown SR6 exhibited remarkable 42% improvement compared unstretched version. advancement, resulting from elevated crystallinity, establishes as viable eco‐friendly substitute single‐use plastics field packaging.
