Seaweed-derived coating developed for fast-food packagingMarie Donlon | November 15, 2022
Researchers from Flinders University in Australia have developed a biopolymer coating material derived from seaweed to be used as a replacement for the plastic coatings currently found in grease-resistant fast-food packaging.
Created in conjunction with German biomaterials developer one • fıve, the seaweed-derived coating has reportedly met the requirements of current grease-resistant packaging materials while simultaneously offering an environmentally circular solution to grease-resistant paper that is generally coated with plastic and other chemicals like polyfluoroalkyl substances (PFASs).
Selecting seaweed for its similar structure to the natural fibers in paper, the researchers used a proprietary processing technique to manufacture the biopolymer sheets that can be coated onto different surfaces. Further, the team enhanced the grease-resistant characteristics of the seaweed through simple modifications that did not diminish the biodegradability or recyclability of the coated paper.
