POLYOLEFINS | MATERIALS
Post-industrial re-use KNF Flexpack, a US-based film converter has improved the quality and consistency of its polyethylene film – which is made completely from post-industrial PE film – thanks to Baeropol T-Blend resin stabiliser from Baerlocher. The technology resolved issues of variable film quality by preventing gels, bubble instability and haze that previously prevented KNF from using post-industrial film in certain applications. In a separate trial, KNF and Baerlocher joined up
with recycling specialist Erema – which reprocessed film scrap stabilised with the Baeropol T-Blend during testing at its facility in Ipswich, USA. “Thanks to the high quality of the post-industrial film incorporating Baeropol T-Blend, we can now run 100% recycled material with confidence in its quality and consistency,” said Ray Glenn, sales director at KNF. Before, it would have had to blend the recyclate
with expensive virgin material. Now, the production rate for recycled material is almost equal to that of prime material, he said. “Further, since film lines can now run more efficiently – and recycled materials can be used in
higher-end products – our business has become more sustainable and cost-effective,” he said. KNF wanted to increase the use of scrap from its
film production processes in other applications but encountered quality problems. The blown film process subjects resin to high-shear and tempera- ture conditions that can cause degradation. Recycling this film without adding stabilisers can cause crosslinking – creating gels and variable melt flow that affect quality and processing. During trials, Baerlocher identified its T-1111 TX
resin stabiliser as a best candidate to help resolve these quality issues.

WE DRIVE THE CIRCULAR ECONOMY.
Whether it is inhouse, post- consumer or bottle recycling: you can only close loops in a precise and profi table way if machines are perfectly tuned for the respective application. Count on the number 1 technology from EREMA when doing so: over 6000 of our machines and systems produce around 14.5 million tonnes of high-quality pellets like this every year – in a highly effi cient and energy-saving way.
