Industrial Packaging Where Batch Consistency Is the Product
Industrial buyers do not need gift-bag printing — they need film that performs the same on the ten-thousandth bag as on the first, and recycled content that survives a corporate sustainability audit. LiHai produces heavy-duty bags and liners from resin it pelletizes itself: stable raw material, traceable batches, 30%–100% recycled content, GRS-certified. From 500 pcs per design, samples in 3–5 working days.

The pain point
Inconsistent Film, Untraceable Resin
Industrial packaging fails quietly: film gauge drifts between batches, puncture resistance varies, and when corporate procurement asks where the recycled resin came from, the answer is a trading company’s invoice. For long-term supply agreements, that variability is a contractual risk.
Our solution
Resin We Pelletize Ourselves
Vertical integration is the specification here: 2 in-house pelletizing lines produce the recycled resin, 2 film-blowing lines convert it, and each production batch is traceable through our GRS scope certificate. Film properties are controlled at the resin stage, not inspected at the door.
| Film thickness | 50–80 µm typical, matched to load and puncture requirements |
|---|---|
| Recycled content | 30%–100% post-consumer, declared per batch |
| Slitting / Printing | 800–1300 mm · printing available up to 10 colours where identification marking is needed |
| 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
- GRS TE-00057717 — batch-traceable recycled content, verifiable online
- SMETA / Sedex ZC5000065444 for corporate supplier audits
- ISO 9001 familiarity; carbon data point for procurement ESG scoring: ~2.6 t CO₂e avoided per tonne of virgin PE replaced (industry estimate)
- Documentation prepared for EU PPWR 2030/2040 alignment; REACH awareness
Case study
Repeat Industrial Supply Into a European System (Anonymised)
A European retail and distribution system sources heavy-duty recycled packaging from LiHai under repeat orders. The agreement’s core requirements were documentary: recycled-content declarations traceable per batch, GRS transaction certificates per shipment, and consistent film performance across deliveries. In-house pelletizing and film-blowing keep raw-material quality stable across the order cycle, and certification packs are issued within 24 hours when corporate procurement requests them.
