Abstract
The instant disclosure provides a die assembly for producing microcapillary film. The die assembly is operatively connectable to an extruder having a thermoplastic material passing therethrough. The die assembly includes a pair of die plates, a manifold, and a plurality of nozzles. The manifold is positionable between the pair of die plates and defining a plurality of film channels therebetween. The plurality of film channels converge into an elongate outlet. The thermoplastic material is extrudable through the plurality of film channels and the elongate outlet to form a multi-layer film. The plurality of nozzles are positionable between the plurality of film channels. The plurality of nozzles are operatively connectable to a source of channel fluid for emitting the channel fluid into the thermoplastic materials exiting the die whereby microcapillaries are formed.
