PP grade with higher toughness to transparent packaging film and sheet has US food compliance

14-Dec-09

New Borpact BC918CF polypropylene brings higher level of toughness to transparent packaging film and sheet –now also with US food compliance. A new polypropylene heterophasic copolymer for packaging film and sheet offers outstanding deep temperature resistance / toughness together with excellent transparency. Borpact™ BC918CF from Borealis, a leading provider of chemical and innovative plastics solutions, has unrivalled 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 U.S. regulations relating to food contact applications. Borpact BC918CF will create even greater opportunities for converters and end-product manufacturers of thermoforming sheets, cast and blown film. Main application areas are modified atmosphere packaging (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.
