Abstract:
A method for producing a multi-layer, microcapillary film (110) is provided. The method involves passing a thermoplastic material (117) into an extruder (100) and through a die assembly (111) operatively connectable to an outlet of the extruder (100). The die assembly (111) includes a pair of die plates, a manifold positionable between the pair of die plates and defining a plurality of film channels therebetween, and a plurality of nozzles positionable between the plurality of film channels. The film channels converge into an elongate outlet. The nozzles operatively connectable to a source (119) of channel fluid. The method further involves forming the film (110) by extruding the thermoplastic material through the plurality of film channels and the elongate outlet, and forming microcapillaries (103) by emitting the channel fluid into the thermoplastic materials exiting the die. The film (110) may have different layers of thermoplastic material.
