Marlex® Polyethylene Resins for Film Applications

Plastic Wrap placed over salad in bowl

Polyethylene films are lightweight, durable materials used across packaging, industrial, agricultural and consumer applications. By selecting the right polyethylene resin and processing method, film producers can balance clarity, toughness, sealability and sustainability requirements. 

CPChem supplies a broad portfolio of Marlex® polyethylene resins engineered to perform across blown and cast film processes, supported by deep technical expertise and global manufacturing scale.

Blown Film

Blown film is the most versatile PE film process, enabling both mono- and multilayer structures with tunable clarity, toughness and tear performance to meet diverse application needs. From food and retail packaging that demand high clarity to industrial, agricultural and hygiene films with specialized strength or optical requirements, blown film technology offers the flexibility to tailor material properties across a wide range of gauges.

CPChem provides a distinct advantage with a broad portfolio of polyethylene resins spanning wide melt index and density ranges, supported by multiple technology platforms and innovative research and development. Our experienced technical support team collaborates with customers to optimize formulations, improve processing performance and accelerate application development, helping unlock the full potential of blown film solutions.

Cast Film

The cast film process offers a fast quench and near-unidirectional orientation, enabling high output rates, excellent gauge control and superior optical properties. These capabilities make cast film ideal for food and retail packaging applications that depend on clarity, consistency and high-quality appearance.

CPChem delivers a distinct advantage with a broad portfolio of high clarity LDPE and LLDPE grades engineered for reliable performance on high-speed cast film lines. Backed by multiple technology platforms, rigorous quality standards and dedicated technical support, we help customers optimize resin selection, enhance processing efficiency and meet demanding application and productivity requirements.

Applications

  • Food wraps
  • Retail packaging
  • Personal care films
