Description
Eco-friendly food packaging solutions use biodegradable polymers and natural fibers to protect food while reducing environmental impact.
Technical
Polylactic acid films degrade via hydrolysis under composting conditions, while chitosan coatings form a semi‑permeable barrier that lowers oxygen and water vapor transmission. Cellulose nanofibrils reinforce paper matrices, reducing oxygen permeability by 70%, and phase‑change materials provide thermal regulation through latent heat absorption.
