In article number 1600024, José A. Heredia‐Guerrero, Athanassia Athanassiou, and co‐workers present new, sustainable composite materials inspired by plant cuticles. These materials are fabricated by the impregnation of fibrous cellulose substrates with a naturally occurring polyhydroxylated fatty acid, and subsequent polymerization of the latter into a polyester. In the image a piece of this new material is shown together with tomato and pepper fruits. Cover image created by Dr. Duilio Farina.
