Yes, you heard right. The first synthetic banknotes were made of a Tyvek material, produced by the multinational company Dupont™. The material is described as unique, non-woven and made from high-density polyethylene continuous filaments. This material is light, difficult to tear, and liquid proof. This material is still used in various industries today, one immediate example would be shipping mailers.
