ABSTRACT:
According to the present invention, the copolymers of ethylene vinyl alcohol are extruded using extrusion equipment coated with a fluoropolymer. This method improves the processability, alleviates/slows down die buildup, improves the extrudate quality by reducing die lines on surfaces of the extruded product.
