Here are stretch-film manufacturers and suppliers that explicitly emphasize circular-economy approaches (recycled content, PCR/ post-industrial recyclate supply chains, recyclability, take-back partnerships or bio/renewable feedstocks). I’ve listed what each company offers and a citation for the claim.

1. Berry Global — Bontite Sustane (30% PCR stretch film)

• What they offer: Bontite Sustane stretch film with ~30% post‑consumer recycled content aimed at maintaining performance while increasing recycled PE in film. (gminsights.com)

2. Manupackaging — Manunature RR (high‑PCR, 100% recyclable lines)

• What they offer: Manunature® RR stretch films produced using post‑consumer recycled LLDPE/LDPE (partnerships with recyclers such as Saica Natur); lines with high PCR content (up to ~50–60% depending on product) and 100% recyclable design intent. They position the product and supply chain explicitly around circularity. (Manupackaging.com)

3. Nolanplastica — Bio Twin / Mix Twin (recyclable, bio and recycled options)

• What they offer: LLDPE/LDPE stretch films sold in biobased and recycled-content “Bio Twin / Mix Twin” lines designed to be 100% recyclable and to reduce CO2. Company messaging focuses on recycled feedstock and circularity. (Nolanplastica.it)

4. Geminor (Norway) — 100% recycled-feedstock bale/stretch film for agriculture and baling

• What they offer: Launched stretch film made from 100% recycled plastic feedstock (agricultural waste streams) for baling — promoted explicitly as a circular-economy solution for agricultural film/recycling loops. Good option if you need film produced from recycled agricultural plastics. (bioenergyinternational.com)

5. Castle Industrial (distributor / manufacturer lines) — Eco Pallet Wrap (≥30% post‑industrial recyclate)

• What they offer: Eco pallet-wrap marketed with at least 30% post‑industrial recycled material, positioned to support circularity while retaining performance for high‑speed lines. (Distributor/producer model; good for U.S. sourcing). (castleindustrial.com)

6. MMP Corp. (Asia supplier) — PCR stretch film (GRS‑certified options)

• What they offer: Machine- and hand-roll stretch films containing up to ~30% PCR, with Global Recycled Standard (GRS) certification for recycled content traceability. Useful if you require certified PCR content. (mmpcorp.com)

7. Other established film makers / converters with circular initiatives

• Ergis (Poland) — major LLDPE stretch-film producer; sells LLDPE/LLDPE-based films and has recycling/flake capabilities in its group (good to contact for Europe-centered circular solutions). (en.wikipedia.org)
• ITW Mima / ITW (manufacturing footprint in Belgium/Ireland) — large film manufacturer; ITW’s divisions have introduced more sustainable film solutions and often support circularity projects (check local product lines). (en.wikipedia.org)

Notes and practical next steps

• Recycled content vs recyclability: Some films use PCR or post‑industrial recyclate (reducing virgin resin), others are biobased, and others are engineered to be readily recyclable in existing PE film streams. Confirm whether you need PCR (post‑consumer), PIR (post‑industrial), biobased, or mechanically/chemically recycled feedstock.
• Certifications & traceability: If verification matters, ask for GRS, Recycled Content certification, or mass-balance documentation from the supplier.
• Performance / line compatibility: Recycled-content films can behave differently—request technical datasheets, machine‑speed compatibility, tack/holding force data, and samples for your wrapping equipment.
• Take-back, regional recycling: For true circularity, inquire whether the supplier participates in take-back programs, local film-collection networks, or has partnerships to ensure the used film is actually recycled.

If you want, I can:

• Narrow this to U.S.-based suppliers only and include distributor contacts and typical lead times; or
• Pull current product datasheets/pricing and local distributors for any two of these companies (I’ll look up the latest product pages and supplier contacts).
