Abstract

An extrusion die (10) for producing a film or sheet of thermoplastic material. The extrusion die includes a die outlet through which a melt stream of the thermoplastic material is extruded as a film or sheet, the die outlet comprising a first die lip (46) and a second die lip (48), a feed entrance in communication with a feed splitter (24) for dividing the thermoplastic material into a first portion and a second portion; and a first die section (14) having a cross flow manifold comprising: a first cross flow manifold section (26) for receiving the first portion of the thermoplastic material, and a second cross flow manifold section (28) for receiving the second portion of the thermoplastic material. A process for making a film or sheet of thermoplastic material is also provided.
