Main Features & Benefits of Vistamaxx™ 3588FL

  • Sealant performance: Excellent low-temperature seal initiation, high seal strength, and reliable sealing for co-extruded films.
  • Film compatibility: Suitable for BOPP, cast PP, and other polyolefin films.
  • High elongation and toughness: Enhances film integrity and resistance to tearing or puncture.
  • Low gel content: Ideal for high-clarity, high-optics film applications.
  • Good processability: Can be extruded, blended, or dry-mixed without special drying.
  • Compliance: RoHS compliant and suitable for certain food-contact applications depending on local regulations.

Typical Applications

  • Sealant layers in co-extruded films: Especially for BOPP or cast PP films where low-temperature sealing and high strength are required.
  • Film & packaging: Enhances flexibility, toughness, and hermetic sealing in film structures.
  • Polymer modification: It can be blended with PP and PE resin to improve softness, impact resistance, or film performance.

Processing & Use Recommendations

  • ExxonMobil Vistamaxx™ 3588FL is suitable for extrusion, cast film, and co-extrusion processes.
  • Optimal processing temperature is typically ~10 °C above the highest melting point of the polymer blend.
  • The FL grade ensures low gel content, maximizing optical clarity and surface quality.
  • When used as a sealant layer, ensure proper film layer structure and sealing temperature window for best results.
