Abstract (en)
[origin: EP0479404A2] A composite packaging film, capable of dispersing in lightly agitated water substantially without visible residues, comprises a continuous water-soluble base film, for example, polyvinyl alcohol, carrying on one or both surfaces a discontinuous, at least partially non-particulate layer of a second plastics material less water-soluble than the base film material, for example, nitrocellulose. The discontinuous layer may be applied by gravure printing. The composite film is advantageously used for packaging detergents or other washing, cleaning or laundry treatment products in water-soluble sachets having reduced tackiness when handled with wet hands.
