Exceed™ 1018RA mLLDPE is a metallocene linear low-density polyethylene resin engineered for demanding blown film applications. Manufactured using ExxonMobil’s advanced metallocene technology, this ethylene-hexene copolymer is widely used in high-performance flexible packaging where consistent processing and reliable film quality are essential.

The resin offers an outstanding combination of toughness, puncture resistance, heat-sealing capability, and optical performance. Its uniform polymer structure ensures excellent process stability and film consistency, while the additive package—including thermal stabilizers and an alternative processing aid without slip or antiblock additives—offers greater formulation flexibility for customized film production.

What Are Key Features of mLLDPE 1018RA?

  • Outstanding Mechanical Strength. ExxonMobil 1018RA offers superior tensile strength, impact resistance, and elongation compared with conventional linear low-density polyethylene. Its balanced mechanical properties enable thinner films to achieve excellent load-bearing performance while maintaining durability throughout packaging, transportation, and storage.
  • Excellent Puncture and Tear Resistance. The resin provides high dart impact strength together with outstanding puncture and tear resistance, helping flexible packaging withstand sharp edges and heavy loads. These characteristics significantly improve package reliability and reduce the risk of product damage.
  • Superior Heat-Sealing Performance. mLLDPE 1018RA delivers a low seal initiation temperature (SIT) and a broad heat-sealing window, enabling reliable sealing across a wide processing range. These properties make it particularly suitable for high-speed packaging lines where strong, consistent seals are essential.
  • Stable Blown Film Processing. Designed for efficient blown film extrusion, the resin exhibits excellent melt strength, bubble stability, and gauge uniformity. Its optimized formulation supports smooth extrusion, minimizes die build-up, and contributes to stable long-term production with improved operational efficiency.
  • Excellent Optical Properties. Films produced with Exceed™ 1018RA feature high gloss, low haze, and excellent transparency. These optical characteristics enhance product presentation and make the resin an ideal choice for premium retail and food packaging applications.
  • Supports Film Downgauging. The exceptional strength-to-weight ratio of Exceed™ 1018RA enables manufacturers to reduce film thickness without compromising performance. This helps decrease resin consumption, lower packaging weight, improve sustainability, and reduce overall production costs.

Main Applications

Exceed™ 1018RA is designed for a wide range of high-performance flexible packaging applications. It is commonly used in food and frozen food packaging, heavy-duty shipping sacks, industrial liners, refuse bags, agricultural films, stretch films, bag-in-box liners, stand-up pouches, form-fill-seal (FFS) packaging, laminated films, barrier film structures, and multilayer coextruded films.
