Polyethylene Applications

Plastic food containers with fruit

Polyethylene applications span a wide range of industries and processing methods, from packaging and consumer goods to industrial pipe and infrastructure. Its unique balance of strength, flexibility, chemical resistance and processability makes polyethylene one of the most widely used polymers in the world.

CPChem Marlex® polyethylene resins support diverse applications across blow molding, injection molding, pipe, film, extrusion and rotational molding, helping manufacturers produce consistent, high-performance products for demanding markets. 

MarTECH loop slurry technology

MarTECH™ Technology: Enabling a Broad Range of Polyethylene Applications

Our proprietary MarTECH™ loop slurry process enables one of the broadest polyethylene product ranges available. This manufacturing flexibility allows rapid transitions between grades with minimal off-spec material, supporting efficient production of polyethylene resins tailored to specific applications and market needs.
