Natural raffia is derived from the Raphia farinifera palm, offering biodegradability and high breathability, making it ideal for high-end fashion and eco-friendly packaging. Synthetic raffia, made from polypropylene (PP), is preferred for industrial baling and heavy-duty outdoor use due to its UV resistance and uniform thickness. For premium retail products, verify the burn test results: natural raffia smells like burning paper and leaves gray ash, while synthetic raffia melts and smells like plastic.
