Bioplast is a thin material that can be used in the form of sheeting for establishing exterior surfaces.

Data's skin consisted of 1.3 kilograms of bioplast sheeting. When he was abducted by Kivas Fajo, the same amount of bioplast sheeting was put into his type 15 shuttlepod to make it seem as if he perished when the shuttlepod exploded. (TNG: "The Most Toys")
