Dow Plastics Additives, a division of Dow Chemical, has teamed up with PolyOne to introduce OnCap BIO L masterbatches, a range of additives aimed at users of bioplastics in the packaging markets.
PolyOne’s OnCap BIO L is based on Paraloid BPM-520, an impact modifier manufactured by Dow that helps improve the impact resistance of opaque, injection-moulded polylactic acid (PLA) products with minimal effect on heat distortion temperature and stiffness. Dow has also selected PolyOne as its exclusive European formulator for converters seeking ready-to-use formulations with Paraloid BPM-520. According to the company, OnCap BIO L additive masterbatch broadens the choices available to brand owners looking to use sustainable polymers in applications such as opaque ice cream and food packaging and semi-durable applications such as cosmetic packaging and housing for laptops or mobile phones. “Brand owners are always on the look out for products which offer improved environmental performance to keep up with consumer demand – but they don’t want to compromise on end-use performance and need to maintain a cost-competitive and efficient production process,” said Robin Madgwick, marketing manager for Dow Plastic Additives. “We’ve worked closely with PolyOne to offer an effective impact modifier which can be made available in user-friendly, pre-dispersed formats that can help further extend the use of bio-based PLA resins into injection moulded durable and opaque packaging, which is a step forward for the industry.”
