Abstract: Hose or hollow profiles of thermoplastic synthetic matls. are extruded continuously and are coated continuously, before cooling completely to room temp., with a soln. or dispersion of a copolymer contg. is not 80wt. % vinylidene chloride. Uniform layers of vinylidene chloride (co)polymers (I) can be applied continuously. The (I) layer prevents passage of water vapour, O2 or odours. The film remains intact during further processing, e.g., cutting to sections.

Abstract: Thermoplastic films are coated with an aq. dispersion of a vinylidene chloride copolymer (contg. >=80 wt.% vinylidene chloride) by applying the dispersion immediately after extrusion of the film. The coated film may be formed into hollow articles, (e.g. beaker, packages).

Abstract: Hollow articles, made by rotation casting thermoplastics, are coated with a soln./dispersion of a vinylidene chloride copolymer on the inner face before they have completely cooled, the coating medium being >=80% vinylidene chloride. The coating is of uniform thickness and bonds well to the surface.
