Borealis Introduces New Transparent Borclear Grade

Produced with proprietary Borstar PP 2G technology, Borclear RE936CF is ideal for the production of transparent films that have superior gloss and provide better pack aesthetics. Unlike other transparent films, it remains transparent (haze 2%) after sterilization.

16/10/08 Borealis, a leading provider of innovative, value creating plastics solutions, has introduced a new grade of Borclear, a unique random copolymer family for highly transparent polypropylene (PP) blown and cast films. Borclear RE936CF was developed for use in food packaging and medical applications and offers film converters and cast film producers a product that provides cost-effective processing and significant end-user benefits including superior optical properties.

Produced with proprietary Borstar PP 2G technology, Borclear RE936CF is ideal for the production of transparent films that have superior gloss and provide better pack aesthetics. Unlike other transparent films, it remains transparent (haze 2%) after sterilization.

Productivity and performance
Today, packaging film converters are facing tough competition and pressure on their margins. Improving productivity on film lines adds value to their operations. Where other films’ optics deteriorate with increasing line speed, Borclear RE936CF allows more than 15% higher film line speed while maintaining equally good optical properties.

Borstar PP 2G technology
Borclear RE936CF was developed using Borealis’ proprietary Borstar PP 2G technology, the second generation of multi-modal processes. Yielding a step change in polymer design, Borstar PP 2G consists of a new catalyst system in combination with process improvements. This results in a simplified process with fewer steps that offers increased safety, through modified catalyst handling.
