Biodegradable multilayer barrier films: Bio-based packaging technologiesRecent Research Landscape
Standard biopolymers like PLA and starch lack the moisture barrier and mechanical toughness required to replace conventional petroleum-based food packaging.
What technical problems is Bio-based packaging technologies addressing in Biodegradable multilayer barrier films?
Starch blend brittleness
(9)evidences
Standard bio-based polymers like starch and PLA often suffer from brittleness or low puncture resistance, leading to structural failure during food packaging applications.
Multilayer interfacial delamination
(12)evidences
Polylactic acid and other biodegradable polymers suffer from high water vapor permeability and rapid hydrolysis when exposed to environmental humidity.
Gas permeability defects
(10)evidences
Polypropylene carbonate films exhibit insufficient heat resistance and mechanical strength for high-barrier packaging applications without chemical modification or multilayer reinforcement.
