Biodegradable pha coating systems: Bio-based packaging technologiesRecent Research Landscape
Standard bio-based polymers lack the moisture and gas resistance required to protect sensitive consumer goods without multi-layer coating integration.
What technical problems is Bio-based packaging technologies addressing in Biodegradable pha coating systems?
Pha substrate adhesion failure
(16)evidences
Standard PHA polymers often exhibit insufficient water and grease resistance for liquid packaging, leading to structural degradation or leakage during storage.
Multilayer barrier permeability defects
(24)evidences
Hydrophilic bio-based substrates like cellulose and lignocellulose lose structural integrity and gas barrier efficiency when exposed to high humidity or water.
