Primary Applications of Exceed 3518CB

  • Food Packaging Films. Exceed 3518CB is suitable for fresh food packaging, frozen food packaging, meat packaging, dairy packaging, snack packaging, and other flexible food packaging applications requiring excellent clarity, sealability, and mechanical strength.
  • Cast Packaging Films. Designed for both monolayer and multilayer cast film structures, including automatic packaging films, laminating films, and high-speed packaging applications.
  • Stretch Films. This material is ideal for pallet stretch wrap, industrial stretch films, and transportation packaging, offering excellent stretchability, load retention, and puncture resistance.
  • Hygiene Films. mLLDPE Exceed 3518CB is widely used in diaper back sheets, sanitary napkin films, medical hygiene films, and other personal care products requiring softness, toughness, and consistent processing.
  • Liquid Packaging. The resin is suitable for liquid food packaging and bag-in-box structures where excellent puncture resistance and secure sealing performance are essential.
  • Multilayer Coextrusion Films. ExxonMobil 3518CB can be used as a structural layer in multilayer coextruded films to improve overall strength, toughness, and puncture resistance while maintaining excellent optical properties.
