ABSTRACT:
In an extrusion coating process of the flow-stretch type in which a ribbon of an aqueous gelatin coating composition is extruded through an elongated orifice onto a moving support and becomes stretched and attenuated in thickness between the orifice and support, at least one visco-elasticity enhancing agent is added to the coating composition in sufficient amount as to disproportionately increase the elasticity of the composition compared to its viscosity so as to render the composition stretchable at viscosities which are substantially reduced compared to what would otherwise be necessary for flow-stretch coatability.
