Recycled Poly Mailers With Numbers Your ESG Page Can Use
E-commerce packaging is bought by the pallet and judged by two audiences: the fulfilment floor, which needs bags that seal and survive transit, and the sustainability report, which needs defensible recycled-content figures. LiHai produces recycled poly mailers on its own pelletizing and film-blowing lines — 30%–100% post-consumer content, GRS-certified, with per-shipment transaction certificates. From 500 pcs per design.
The pain point
Volume Packaging, Unverifiable Content
Mailers are a high-volume, low-margin line, so content claims are often accepted on trust. But under EU PPWR recycled-content targets and retailer ESG questionnaires, “trust” is no longer a documentation strategy.
Our solution
Mailers From Our Own Recycled Resin
We pelletize post-consumer material in-house (2 lines), blow the film (2 lines) and print up to 10 colours — so recycled content is a measured process input, and seal strength and film consistency are controlled at the source rather than inspected after the fact.
| Recycled content | 30%–100% post-consumer (GRS TE-00057717) |
|---|---|
| Film thickness | 50–80 µm typical, matched to parcel weight |
| Printing / Slitting | Up to 10 colours · 800–1300 mm |
| MOQ / Pricing tiers | 500 pcs per design · 5,000 / 20,000 / 100,000 pcs |
| Sampling | 3–5 working days, free on standard lines |
Evidence points
Evidence Points for the Sustainability Report
- Carbon context: replacing 1 t of virgin PE with recycled content avoids roughly 2.6 t CO₂e (industry estimate) — a figure you can quote with its basis stated
- GRS transaction certificate per shipment; scope certificate TE-00057717 verifiable online
- SMETA / Sedex ZC5000065444 for fulfilment-network social audits
- Documentation aligned to EU PPWR 2030/2040 recycled-content targets; EuCertPlast familiarity
Case study
E-Commerce Packaging for a European Retail System (Anonymised)
A European retail system sources recycled mailers for its e-commerce fulfilment from LiHai. The programme’s requirements were documentary as much as technical: recycled-content declarations per shipment, GRS transaction certificates for group ESG reporting, and consistent seal and film performance across repeat orders. Vertically integrated production lets each re-order run against the approved specification, with certification packs issued within 24 hours on request.
