New Borealis PP brings toughness and transparency to packaging

Borealis, a provider of chemical and innovative plastics solutions, supplies a new polypropylene heterophasic copolymer for packaging film and sheet that offers good deep temperature / toughness together with excellent transparency.

The Borpact BC918CF has outstanding stiffness, heat- and impact resistance, combined with high gloss and low haze. It provides the high clarity typical of PP homopolymers together with the tough, non-brittle performance of heterophasic copolymers. And thanks to a new additive package, the material complies with all European and US regulations relating to food contact applications. For Borpact BC918CF the main application areas are modified atmosphere pachaging (MAP) trays for food packaging as well as film for stand up pouches (SUP) and labels.

The performance benefits of Borpact BC918CF translate into processing benefits for packaging processors. It allows significant downgauging compared to alternative material solutions, resulting in material and cost savings of up to 20%. High toughness converts into minimal low-temperature brittleness in finished products.

The combined mechanical and aesthetic advantages ensure attractive packaging with reduced potential for handling or storage-related damage. This is particularly important for items stored at low temperatures such as MAP trays for various chilled foods, including fruits and meats. An optimal balance of easy tear, stiffness and good aesthetics make the new grade ideal for retortable stand-up pouches, label films and carrier layers for peelable lidding films.

Borpact BC918CF is based on Borealis' proprietary Borstar technology, a multi-modal process that enables the molecular tailoring of polyethylene and polypropylene to provide solutions that meet the exact needs of the customer.
