en.Wedoany.com Reported - ExxonMobil's Signature Polymers has developed two mono-material polyethylene film solutions containing up to 35% post-consumer recycled (PCR) content, addressing a pressing sustainability challenge for the packaging industry while maintaining the performance and processing standards required for high-speed hygiene compression packaging operations.
Hygiene compression packaging converters are under increasing pressure to deliver films with sustainability benefits—including downgauging, recycled content addition, and recyclability design—without compromising packaging performance or production efficiency. The challenge intensifies when incorporating PCR content, as recycled materials can impair film properties and handling characteristics. ExxonMobil states that in response to consumer preferences and brand owner commitments, many converters face the challenge of developing hygiene compression packaging films that combine these sustainability advantages.
The solution comes from ExxonMobil's newly launched Signature Polymers product portfolio brand. Through this brand, the company unifies its polyolefin products, aiming to simplify product portfolio navigation and foster value chain collaboration to address complex sustainability challenges in packaging.
The ExxonMobil Signature Polymers team collaborated across the value chain to develop formulations based on just three polyethylene grades: Exceed Tough+ m 0518 polyethylene, ExxonMobil HD 6207FL polymer, and ExxonMobil LD 07523 polymer. This simplified approach helps optimize logistics and production efficiency while achieving sustainability goals. In a case study report, ExxonMobil noted that using only three polyethylene grades enables film downgauging and/or incorporation of up to 35% PCR content while still meeting performance and processing requirements. The Exceed Tough+ m 0518 metallocene polyethylene serves as the backbone, enhancing film toughness and puncture resistance; combined with ExxonMobil HD 6207FL polymer, the formulation provides high stiffness and creep resistance, ensuring dimensional stability during and after packaging. A small addition of ExxonMobil LD 07523 polymer adjusts processing and optical properties.
The validation process involved comprehensive testing across multiple stages of the packaging value chain. Films were produced at ExxonMobil's facility, then converted on Hudson-Sharp's Apollo wicket machine, and subsequently formed and sealed on Optima equipment. The Apollo wicket machine is suitable for mono-material polyethylene films, maintaining good performance even at very thin gauges. ExxonMobil states that due to the excellent sealing properties and easy side-cutting and punching characteristics of the two polyethylene film formulations, high machine output can be achieved on the equipment. Tests on Optima equipment demonstrated commercial viability, with films exhibiting easy processability, sufficient stiffness to prevent film elongation during handling, and good gripper friction coefficients. These properties are critical for maintaining packaging shape and function, ensuring product security. The final films achieved high-speed, seamless bagging operations without requiring adjustments to end-user machine settings.
The films also achieve multiple sustainability goals: downgauging through improved material performance, significant PCR content, and maintaining a mono-material polyethylene structure that supports recyclability. Packaging integrity and visual appeal are not compromised. ExxonMobil notes that the two polyethylene film formulations are designed to meet consumer expectations for packaging solutions with sustainability benefits such as downgauging and PCR content, while ensuring good printability and optical properties to support product promotion. According to ExxonMobil Signature Polymers, the solution demonstrates that environmental responsibility and commercial performance can coexist in hygiene compression packaging applications.
