ADDITIVES | RECYCLING
Cleanfarms, a Canadian agricultural recycling program provider, is working with BASF on recycled content in packaging
The company said that in reprocessing of
recycled polyethylene (rPE) film, a Baeropol T-Blend is designed to be fed directly into a cutter-compactor unit. The additive has been shown to allow fewer gels and fewer bubble breakages during film processing. The company said that another T-Blend improved processing of recycled high-density PE (rHDPE) for extrusion blow moulded packaging. BASF’s Irgastab range are advanced stabilisation solutions for specific conditions. The additives can be used in recycled polymers, where they can act as a thermal stabiliser to provide long-term durability, a processing stabiliser to protect the polymer during processing, and as a nucleating agent to increase crystallisation temperature and improve mechanical properties. At the K2025 show, the company plans to highlight a closed-loop agricul- tural packaging initiative that uses Irgastab to boost recycled content in a package for herbicide made from recycled agrochemical container plastics. Partners in the project are Cleanfarms, a Canadian provider of end-of-life packaging management in agricultural plastics, and McKenzie, which provides bulk containers for agricultural and industries chemicals.
Dover Chemical has expanded its Doverphos
LGP-12 line into a broader platform of solutions for recycling and film extrusion. “We see strong adoption opportunities across packaging, film, and moulding applications as converters and brand owners push for higher recycled content without sacrificing performance,” the company said. Doverphos LGP-12 is a proprietary liquid polymeric phosphite antioxidant with a high molecular weight structure (>1,500 MW) that reduces additive migration compared to legacy stabilisers with lower molecular weight (200–900 MW). Beyond stabilising against thermal and

oxidative degradation, LGP-12 also functions as a PFAS-free processing aid, reducing melt fracture, minimising die lip buildup in blown film, and reducing plate-out in cast film extrusion. “These dual benefits deliver stable melt flow, extended run times, and cleaner surfaces [without buildup] – es- pecially valuable in PCR [or] PIR [post-industrial recycled] applications,” the company said. DoverClear is a PFAS-free, silicone-free line of polymer process aids and gel reducers designed to improve both optical and mechanical perfor- mance in LLDPE/LDPE extrusion. “DoverClear products enhance clarity, eliminate melt fracture, reduce die lip buildup and plate-out, and cut gel formation – resulting in smoother films, fewer defects, and less downtime for cleaning,” the company said.
Additive platform DoverCycle is the company’s newest branded additive platform for upcycling recycled-content polyolefins, especially streams with high levels of PIR and PCR. “By combining proprietary additives (including LGP-12) with converter-focused techni- cal support, DoverCycle enables better MFI [melt flow index] retention, fewer gels, and improved recyclate quality, making higher recycled content feasible without sacrificing performance,” the company reported. The products are available in neat blend or masterbatch formats, tailored for both US and EU markets. Italian plastics additives company Greenchemicals
acquired additives producer Polichem in Novem- ber 2024. The acquisition included Polichem’s production site, analytical facilities, and application lab in Garlasco, near Milan, complementing Greenchemicals’ headquarters in Desio, Italy. The move gave Greenchemicals additional products for mechanically recycled polymers, including Poli- chem’s high-performance stabilisers. Other types of additives from Polichem for recycled polymers include nucleating and clarifying agents, mould release agents, impact modifiers, chain extenders for polyamide (PA), intrinsic viscosity (IV) enhancers for PET, and dispersing molecules. Brüggemann introduced Bruggolen R8897, a new thermostabiliser designed to improve the properties of polypropylene (PP)-EPDM recyclates from front-end applications. “As the benchmark in its class, it is based on an innovative chemical concept that ensures excellent retention of mechanical properties during long-term heat aging. Laboratory tests show an improved level of residual Charpy impact after long term heat aging,” the company said.
