Vistamaxx™ propylene-based elastomers enhance performance in extrusion laminated flexible packaging film structures

Chips and Pretzels

Adding Vistamaxx™ propylene-based elastomers to the extrusion extrudate when laminating unprimed biaxially oriented polypropylene (BOPP) films contributes to customer-friendly packaging for food products such as snacks and sauces. Manufacturers of extrusion laminated flexible packaging films also gain the opportunity to simplify processing, reduce costs and enhance sustainability through the elimination of primers.

Benefits of using Vistamaxx propylene-based elastomers in extrusion laminated packaging film include:

  • Good adhesion to reverse printed and metalized packaging films, without use of primer 
  • Enhanced adhesion to clear biaxially oriented polypropylene (BOPP) and OPET films relative to LDPE 
  • Enhanced tear and puncture resistance relative to LDPE 
  • Food contact compliance 
  • Organoleptic neutrality 
  • Good optical properties, including low haze and low gels 
  • Friendly processing on existing extrusion equipment

By replacing the primer step between printed substrates and the extrudate layer, and reducing the amount of energy required for drying, Vistamaxx can deliver a more sustainable extrusion laminated flexible packaging structure that also is easier to recycle.
