Abstract

The invention relates to a coextrusion die (10) for producing a multilayer film or sheet of thermoplastic materials. The coextrusion die includes a die outlet (12), a first die section for producing a core layer, a second die section for producing a first skin layer, the second die section having a cross flow manifold, the cross flow manifold having a flow path wherein a portion of a melt stream of the thermoplastic material traverses the second die section's length more than once, and a third die section for producing a second skin layer, the third die section having a cross flow manifold, the cross flow manifold having a flow path wherein a portion of a melt stream of the thermoplastic material traverses the third die section's length more than once.
