ExxonMobil Exceed XP 7 Series: Ultra‑Performance LLDPE Resins for Stretch, Shrink, Packaging and Greenhouse Films

ExxonMobil’s newest Exceed XP 7 LLDPE resins are the result of a proprietary hexene catalyst that delivers performance metrics never before seen in a single polymer. The XP 7021 and XP 7052 grades combine a low density of 0.911–0.912 g/cm³ with a fractional melt index that yields a film with unprecedented elasticity, puncture energy of up to 2.3 J/mil, and dart impact resistance of up to 900 g on a 25.4 µm film. According to ExxonMobil research, this unique blend gives converters a single‑resin solution for applications that previously required multiple materials.

“Extending the extreme performance of our Exceed® XP portfolio to ‘never seen before’ levels, these new grades help the value chain create innovative solutions for specific application needs,” says Michael Vinck, Global PE New Products Marketing Manager. ExxonMobil is collaborating with partners to develop formulations that were once thought possible only in the future, now achievable today.

• Stretch Hood Films: High HEVA‑equivalent elasticity combined with strong holding force eliminates the traditional trade‑off, enhancing pallet stability and product protection. The new grades also deliver low haze for clear barcode and QR code readability, and the high elasticity accommodates minor gauge variations. Tests with Signode’s Lachenmeier equipment confirmed a single‑resin solution that is mono‑material and recyclable¹.
• Collation Shrink Films: Operate at low temperatures—down to 120 °C (248 °F)—reducing energy consumption and protecting heat‑sensitive goods. The films maintain high shrink speeds and can eliminate cardboard trays in many cases, a rarity in the market.
• Primary Packaging Films: Sealed at low initiation temperatures, these films avoid block issues and improve friction and optical quality. Flex‑crack resistance is exceptional, with tests showing an average of only one hole per ten thousand cycles. The fractional MI and 0.912 g/cm³ density prevent seal thinning without added LDPE.
• Greenhouse Films: Combining softness, clarity, and extreme dart/puncture resistance, these films provide greater integrity and longer service life. Farmers can benefit from extended growing periods and potentially higher yields.

“Films made with these new grades give farmers longer, better growing conditions, potentially boosting crop yields to meet the world’s growing food demand,” Vinck adds.
