Biodegradable liquid barrier packaging: Bio-based packaging technologiesRecent Research Landscape
Standard bio-resins lack the moisture and oxygen resistance required for liquid food storage, necessitating integrated multi-layer coatings and molded pulp structures.
What technical problems is Bio-based packaging technologies addressing in Biodegradable liquid barrier packaging?
Hydrocolloid thermal degradation
(6)evidences
Porous biodegradable substrates fail to contain liquid foodstuffs without a barrier, leading to structural softening and product seepage.
Resin layer delamination
(5)evidences
Porous biodegradable substrates like pulp or starch foam absorb liquid contents or slurries, leading to structural softening and surface lifting during storage.
