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.
