This improves processability at high levels of rPET, reducing blowouts, improving productivity, allowing for higher levels of rPET use, and also lightweighting.

Consumers and investors alike are paying close attention to plastic packaging and its potential negative impact on the environment. In 2019, the EU enacted its Single Use Plastics directive aimed at reducing the impact that such products have on the environment. These commitments and mandates will continue to drive the high and increasing demand for recycled plastic bottles.

This region of the world maintains a high sensitivity to preserving nature and the environment, and the producer’s desire to look for alternative material solutions not yet required by law follows this cultural tendency. THE IMPACT By replacing traditional sealing materials with non- halogenated OnFlex S HF TPE, Schneider-Electric NB (Strömfors) was able to offer its customers several significant benefits: • For flexibility in processing, OnFlex S HF TPEs can be supplied in either natural or pre-colored grades. Natural grades can be colored during processing with compatible products from Avient’s OnColor™ color concentrate line. • The non-halogenated solution has a density 0.4 g/cm3 less than a traditional halogenated material, and this density advantage makes it price competitive with the traditional solution. • High-flow properties of OnFlex S HF TPE allow the gaskets to be overmolded in multi-cavity tools (up to 12 cavities per tool).
