To me -- of course I can't speak for anyone else's psychic perceptions! -- bioplastics feel like autumn leaves, dry straw, and the like. They've got a gritty quality but they don't have the slimy feeling. On the other hand, bioplastics that include a lot of noxious additives feel like autumn leaves that have been sprayed with sludge...
