Seaweed-based coating for high-barrier and plastic-free paper packaging
SeaSol introduces a seaweed-based coating developed via Reactive Extrusion Extraction (REE) that provides superior grease, moisture, and oxygen barriers for paper packaging. This compostable and recyclable solution supports a circular economy by eliminating microplastics in food packaging.
Overview
SeaSol presents an innovative seaweed-based coating technology designed to enhance the barrier properties of paper packaging. Utilizing the Reactive Extrusion Extraction (REE) method, this technology delivers superior grease, moisture, and oxygen barriers while being entirely microplastic-free, compostable, and recyclable within single-stream fiber systems. This solution is particularly suitable for food packaging, promising a sustainable alternative to traditional plastic coatings. Additionally, SeaSol's material can function as a moldable additive and binder for molded fiber, enhancing the structural integrity and performance of the packaging.
Technical specifications
Key features:
- Developed via the Reactive Extrusion Extraction (REE) process, optimizing the use of seaweed biomass.
- Provides high-performance grease resistance with tailorable properties (KIT 7-12) and variable coat weights (2-100 GSM).
- Strong hydrogen bonding with cellulose fibers ensures uniform application without synthetic binders.
- Safe for direct food contact and adheres to GRAS standards.
- Functions as a moldable material and binder, improving fiber-based product performance.
Technology readiness level
Currently, the technology is at TRL 4, having undergone trials to demonstrate its barrier properties and application potential. Future validation efforts include refining the REE method, optimizing barrier performance, and conducting pilot-scale trials with industry partners to scale and commercialize the technology.
