ExxonMobil has teamed up with Malpack, a Canadian packaging producer specializing in film extrusion, to develop a high-tenacity, power pre-stretch film using ExxonMobil’s newly launched Signature Polymers portfolio.

Integration challenge

ExxonMobil and Malpack faced the challenge of integrating ExxonMobil’s performance polymers into Malpack’s existing formulations to enhance film performance. The companies said the collaboration led to the development of a new stretch film with high tenacity, strong holding force, and reliable load stability across all pre-stretch levels.

A key component of the formulation is Exceed S 1716 metallocene polyethylene (PE), part of ExxonMobil’s Signature Polymers portfolio. Used as a discrete layer within a nine-layer film structure, the resin allowed Malpack to streamline production by eliminating the need for blending, according to the companies. It also delivered strong processing performance on wide, 4.5-meter extrusion lines.

According to the companies, Exceed S 1716 maintained high tenacity while offering excellent processability. Compared to Exceed m 3518 metallocene PE processed under the same conditions, the new resin showed only minimal impact on head pressure, motor load, and melt temperature — contributing to efficient and stable film production.

The resulting stretch film offers a combination of performance and efficiency designed for demanding packaging applications, according to the companies. Key benefits include:

ExxonMobil’s Exceed Flow m 1716 polyethylene delivers a combination of high flow and high tenacity — two characteristics typically considered at odds, the companies said, adding that this balance enabled faster line speeds, lower extrusion pressure, and reduced motor load compared with traditional high-tenacity resins. The companies said the result was smoother cast film processing and consistent extrusion performance, opening the door to downgauging opportunities without compromising load stability or holding force — key metrics for stretch film quality.

Pushing limits of pre-stretch film design

Malpack, which brings more than four decades of experience in film manufacturing, leveraged the Signature Polymers platform to push the limits of pre-stretch film design. The company said the project illustrates how tailored material selection and close collaboration across the value chain can yield tangible gains in both performance and production economics.

ExxonMobil said it introduced its Signature Polymers brand to unify its polyolefin offerings under a single identity, aiming to simplify portfolio navigation and foster closer partnerships across the supply chain.
