TPU Film for Flexible Packaging
Stronger, lighter, and more sustainable than PE or PVC. Discover how TPU film is quietly revolutionizing the $250B flexible packaging industry.
Unmatched Mechanical Strength
Without Sacrificing Flexibility
Traditional packaging films force you to choose between durability and flexibility. TPU film breaks this trade-off — delivering both in a single, thinner layer.
- Heavy-duty packaging (construction, metal parts): Shore hardness 85A–95A
- Lightweight consumer goods (snacks, pet treats): 40–70 microns, high elongation
- Sharp-edge products: replace 120μm PE with 60μm TPU to cut cost & weight
Superior Barrier Properties
for Sensitive Contents
Moisture and oxygen are the enemies of shelf life. TPU offers a monomaterial barrier solution — no multi-layer lamination or aluminum foil required.
- Shelf life extended from 12 to 18 months
- Packaging cost reduced by 22% (no lamination step)
- Recyclability greatly improved (monomaterial vs. mixed laminates)
Evaluation Checklist: Request OTR/WVTR-specific samples → Test 72h accelerated aging at 40°C/75% RH → Verify FDA / EU 10/2011 food-contact compliance.
Heat Sealing Performance
That Cuts Waste
Seal failures cause leaks, rejects, and customer complaints. TPU’s lower melting point and superior melt flow dramatically reduce defect rates and increase line speed.
Start at 145°C. Lower by 5°C if charring; raise by 5°C if seals are weak.
Reduce from 1.5s (PE) to 1.0s — gain up to 30% more packages per minute.
Use 2–3 bar — lower than the 4–5 bar required for thick laminates.
Chemical Resistance &
Compliance That Matters
Packaging for industrial chemicals, medical fluids, or agricultural products demands materials that maintain integrity in harsh conditions. TPU is certified and proven.
- Agricultural: fertilizer & pesticide sachets
- Industrial: oil-based lubricants, adhesives, solvent bags
- Medical: sterilization fluids, saline IV bags
Certifications: SGS · REACH · RoHS · FDA — third-party verified by Xin Gen Tech.
The “Rapid Sampling” Advantage
— A Game Changer for R&D
New product development in packaging is often slowed by 4–6 week sample lead times. Our in-house 400mm pilot line changes everything.
Received a production-width (400mm) sample in 5 working days (vs. industry average of 21 days). Tested, approved, and into pilot production within 2 weeks total.
Need 120μm at Shore A 80? The pilot line can produce it directly.
The 400mm width fits most lab-scale laminators — no special equipment needed.
Add UV stabilizers, flame retardants, anti-fog, or antistatic properties on request.
Sustainability: Monomaterial
Packaging Is the Future
With the EU Single-Use Plastics Directive tightening and consumer expectations rising, multi-layer laminates are losing ground. TPU as a monomaterial offers a cleaner, more recyclable path forward.
- Design new product lines as 100% monomaterial TPU (no laminates)
- For existing lines: test replacing one layer of multi-layer structure with TPU
- Request sustainability documentation: OEKO-TEX or SGS recycling certificates
Proven ROI Across Real Deployments
Based on market data and real customer cases — including a Brazilian bulletproof glass lamination project.
| Metric | Before (PE / LLDPE / Laminate) | After (TPU Film) | Improvement |
|---|---|---|---|
| Material cost | Baseline | Thinner gauge, less waste | −15% to −30% |
| Sealing speed | 1.5s dwell, 170–190°C | 1.0s dwell, 145°C | +20% to +40% throughput |
| Seal failure rate | 3.2% (LLDPE coffee case) | 0.4% | −88% defect rate |
| Shelf life | 12 months (wound dressing case) | 18 months | +50% extension |
| Recyclability | <10% (multi-layer laminate) | 98% (monomaterial TPU) | Near-zero waste scrap |
