Curling ribbon is made of non-woven poly-satin, nylon, or polyester material. These are all textile yarns bonded by a sticky plastic that is smooth with a sheen finish. Poly satin ribbon is spill-resistant and waterproof and is often used for crafts and decorations.
Poly curling ribbon is made out of polypropylene which will curl with the use of scissors or a knife. Gently glaze the ribbon over the scissor or knife. Try to be as gentle as possible so the ribbon does not break. Curling ribbon is typically used for balloon decorations and gift wrapping.
