Effects of the Glycerol/Quercetin Ratio on the Structure and Tensile Behavior of PVA-Based Films

Poly(vinyl alcohol) (PVA)-based films containing glycerol and quercetin were prepared by casting as potential active-packaging materials. The effects of the glycerol/quercetin ratio on structural, thermal, mechanical, barrier, and antioxidant properties were investigated. Neat PV...

Structure–Property–Durability Relationships in Grape-Derived Pectin/Kraft Lignin Films Before and After Accelerated UV Aging

Pectin films are promising renewable materials for biodegradable coatings; however, their high hydrophilicity and limited resistance to ultraviolet (UV) radiation restrict practical applications. This work investigated the influence of kraft lignin (0–5 wt%) on the structure–prop...
