Abstract

Non-stick protection can be given to the surfaces of thermoplastic material which has a tendency to become stuck to other thermoplastic surfaces during storage, especially during the heat of the summer months. By placing a film of (1) a salt selected from (a) a hydroxy alkyl sulfonate salt and (b) and alkyl sulfonate salt, and (2) an alkyl sulfate salt on the surface of the thermoplastic, sticking can be reduced or totally prevented.
