New Borealis Borpact PP Packaging Grade Delivers Unique Optical Performance

Borealis brings a new polypropylene Borpact grade to film converters and product manufacturers which offers solutions to the packaging industry due to a unique combination of good low temperature resistance, high stiffness, high heat resistance plus excellent optical properties.

Food packaging, pouches, peelable lidding film and film bottle labels are among the application areas set to benefit from Borpact BC914TF. With this development, polypropylene can be used in a number of new sectors, such as in labelling and modified atmospheric packaging (MAP) trays for meat and fruit.

Borpact BC914TF is an innovative heterophasic copolymer for thermoformed, cast and blown film. It can deliver easy-to-process, user-friendly and attractively-finished packaging through a brand new combination of properties. The latest addition to the Borpact generation provides the following typical benefits:

  • Label film, for example, transparent, printed labels for bottles: high stiffness, good optics, good punching
  • Food packaging, for example printed sleeves for fresh and frozen bread: high stiffness, sterilisable
  • Retortable stand-up pouch, for example, for fresh pet food: easy tear opening; FDA approval; high seam seal strength
  • Carrier layer for peelable lidding film, for example, on microwaveable food containers: high stiffness, good processing, high heat resistance
  • Transparent thermoformed cups and trays, for example, low temperature or microwaveable food applications, such as ready-to-eat food: good low temperature resistance, good optics and thermoformability.

Peter Niedersüß, Product Development Engineer for Borealis' film business, comments: "By combining the well-established properties of polypropylene heterophasic copolymers with especially good transparency and optics, Borpact BC914TF will ensure manufacturers achieve an attractive, high-quality finish to their packaging. Consumers will benefit from the convenience of new packaging types. These include easy-open pouches replacing tinned foods."
