What this pellet actually is
The material is a post-consumer recycled polyolefin recovered from the non-fibre fraction of post-consumer packaging. LDPE dominates because that is what carton laminates are made of, with smaller shares of HDPE and polypropylene from caps and closures. Around 10% of the mass is aluminium from the carton's barrier layer, dispersed as fine flakes through the polymer matrix.
That aluminium is a feature, not a contaminant. It raises density and stiffness, improves dimensional stability in thick-walled parts and gives better acoustic mass than unfilled polyethylene. It is also why this material is not the same as recycled HDPE from bottles, and should not be specified as if it were.
Processing on standard equipment
No new machinery is required. The pellet runs at 180–220 °C on conventional injection moulding and extrusion lines. Because the melt carries a mineral load, we recommend generous gating, moderate injection speed and adequate venting; screw and barrel wear is comparable to other filled polyolefins.
Shrinkage is lower and more predictable than unfilled LDPE, which is usually welcome in profiles and thick sections. Colour is a dark grey-to-black base, so it suits parts where the finish is functional rather than decorative.
Consistency and documentation
The single biggest failure mode in recycled polyolefin supply is batch-to-batch drift: MFI and ash content wander because feedstock is mixed from unrelated sources. We batch by source and process in homogeneous 60-tonne lots, so a mould that is dialled in for one batch behaves the same on the next.
Every batch ships with a specification against UNE 53925:2026 and traceability documentation covering origin and recycled content, which is what your customers' Scope 3 and CSRD/ESRS E1 reporting will ask for. Certified product carbon footprint figures are available under NDA.
Applications that work well
Plastic pallets, technical profiles, decking and fencing, urban furniture and planters, cable drums, bins and containers, acoustic barriers, and non-structural construction elements. In short: durable goods, outside food contact, where stiffness and weather resistance matter more than transparency or certified virgin resin.
- Injection moulding — pallets, crates, bins, street furniture components
- Profile extrusion — decking, fencing, slats, technical profiles
- Compression moulding — thick-section boards and panels
- Compounding — as a recycled carrier in filled or coloured blends
Formats, volumes and lead times
Finished pellets are the default. For recyclers and compounders with their own washing and pelletising capacity, we also supply unwashed and washed bales, which lower the input price and let you control the final compound yourself.
Volumes start at a 60-tonne batch and scale to continuous monthly supply contracts. Deliveries are palletised in 1,000 kg big bags for European destinations. Tell us your annual volume and target specification and we will confirm availability and pricing.
