Multilayer pipes and tubes can be produced with the coextrusion or the coextrusion coating processing technique.

• Coextrusion coating of EVAL™ in multilayer pipes: plastic pipes can be coated with an EVAL™ layer to improve the barrier properties.
• Coextrusion of EVAL™ in multilayer pipes: multilayer pipes can also be produced via inline coextrusion processing.
• Coextrusion of EVAL™ in multilayer tubes: EVAL™ coextruded tubes have better barrier properties to gases, flavors and aromas.
