Seaweed Biopolymers in Packaging
Summary
This review rounds up existing research on packaging made from seaweed instead of plastic—think edible water pods and coatings for takeout containers. Because these materials break down naturally and can even be eaten, they offer a promising way to cut down on plastic waste and the microplastics that end up in our food, water, and bodies. The catch: this is a summary of current science, not new lab results, so more work is needed before seaweed packaging replaces plastic on a large scale.
The rapid increase in plastic pollution has intensified the search for sustainable and biodegradable packaging materials. Seaweed-derived biopolymers have emerged as promising alternatives due to their biodegradability, renewability, film-forming ability, and functional properties. Polysaccharides extracted from marine macroalgae, including alginate, carrageenan, and agar, are widely explored for edible films and bio-packaging applications. Seaweed biofilms possess excellent oxygen barrier properties, antimicrobial potential, and compatibility with active packaging systems (Sudhakar et al., 2021). Furthermore, industrial innovations such as edible water pods and biodegradable takeaway coatings demonstrate the commercial viability of seaweed-based packaging technologies (InsightAce Analytic, 2026). This review summarizes the chemistry, production methods, applications, advantages, limitations, and prospects of seaweed-derived biofilms for sustainable food packaging.
