content) and blown film extrusion for consumer packaging (improved bubble stability at higher loading of PCR material),” said Frederix. When adding post-industrial recycle to stretch film, the masterbatch has been found to improve stretch film performance when added to the converting step. Other products include Evercycle PP-101S for
stabilisation in HDPE and PP rigid packaging, and Evercycle PET-102D (pellet form) and 103D (liquid form) for colour control in PET bottles, trays, and fibres.

formation.” He said that if a recycler switches from using a stabiliser in masterbatch form to the NDB form, they can lower the dosage and eliminate the carrier resin, which is often virgin plastic. SI Group also offers Evercycle LD-104P, a masterbatch that can be applied both in the recycling and converting step when working with rL(L)DPE resin. “Beyond protecting the polymer during recycling to prevent gel formation, the masterbatch has proven to create additional value for converters in both cast stretch film (improved mechanical performance and increased recycled
In addition to stabilisers, Frederix said there is a need for compatibilisers. “Although sorting and washing technologies are advancing, there is a need for specific compatibilisers to handle impuri- ties and cross-contaminations that remain in the PCR stream after the washing step.”
Growth in rPP In late 2023, Milliken announced a partnership with Pan Era Group, one of Asia’s largest PP recycling companies. Using Pan Era Group’s expertise in collecting and producing recycled PP resin, the partnership aims to improve the perfor- mance of transparent recycled PP resin and
