C-5384 - 36 - VINYL FILM/SUBSTRATE LAMINATE Abstract of the Disclosure The use of an internally plasticized vinyl chloride film and a fabric backing, preferably a non- flame retardant fabric backing, as the substrate in a vinyl film/substrate laminate yields a product having a lower rate of smoke generation when burned than is pro- duced by a conventional laminate of an externally plasti- cized vinyl film and a fabric backing.
