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: 5-Ply plastics film laminate, comprising a PVDC core lamina with thermoplastics film bonded to both surfaces, using adhesion-promoting layers, is prepd. by applying adhesion adjuvant dispersion onto a thermoplastics film and drying; applying an aq. dispersion or vinylidene chloride polymer onto the layer of adhesion adjuvant and drying; applying a further layer of adhesion adjuvant and drying; and laminating the composite prod, on that side coated with adhesion adjuvant, with a thermoplastics foil. The PVdC layer can be made very thin eg, 0.004-0.012 mm. Used for packaging of hygroscopic materials; and food packaging.

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.
