ExxonMobil, one of the largest publicly traded international energy companies, uses technology and innovation to help meet the world's growing energy needs. The company recently launched its new ExxonMobil Signature Polymers portfolio brand, which focuses on delivering best-in-class service and partnerships within the polymers industry. ExxonMobil Signature Polymers unifies ExxonMobil's polyolefin products under a single brand, simplifying portfolio navigation and promoting enhanced collaboration across the value chain.

ExxonMobil partnered with Winpack Group, a leading flexible packaging converter in Chile, to address growing demand for circular solutions that support the country’s Extended Producer Responsibility (EPR) laws. Leveraging the ExxonMobil Signature Polymers portfolio, including Exceed™ and Exceed™ Tough performance polyethylene (PE), the collaboration aimed to develop advanced stretch films that incorporate high levels of post-consumer recycled (PCR) content without compromising film performance or processing efficiency.

“Increasing the amount of PCR content in our film formulations can deliver solutions that contribute to plastic circularity, creating opportunities to grow our market share through new businesses,’’ said Andres Baboun, General Manager at Winpack. “Due to Extended Producer Responsibility (EPR) regulations progressing in Chile, there is a high demand from brand owners for film solutions that incorporate PCR content.’’

The team successfully produced manual and automatic 7-layer stretch films containing up to 50% PCR content. The films maintained critical mechanical properties, including stretchability, cling, and load containment. Vistamaxx™ performance polymers, also part of the ExxonMobil Signature Polymers portfolio, were used to enhance cling, ensuring film functionality in demanding logistics applications.

Key results include:

• Films incorporate up to 50% PCR content while maintaining strength, cling, and load stability with no compromise in performance.
• Compatible with both manual and automatic stretch film applications, performing comparably to traditional virgin-based options.
• Helps Winpack process an estimated 300 additional tons of recycled material each month, enhancing operational efficiency.
• Allows brand owners to meet evolving market demands without changes to equipment or production processes.

“Using Exceed performance polymers allowed for the increased incorporation of PCR content in the film without affecting the final stretch performance,’’ said Juan Manuel Osorio, Packaging Division Operations Manager at Winpack. “Laboratory test results demonstrated that the films comply with internal safe wrapping protocols standards for safe load protection, while delivering solutions that can contribute to a more circular plastic economy in Chile.”

These results demonstrate how ExxonMobil Signature Polymers deliver high-performance packaging that matches virgin material quality without any compromise.
