2. Mechanical durability
Incontinence products endure shear forces during movement. TPU’s tensile strength (typically 20–50 MPa) and elongation (up to 600%) outclass PE films (10–20 MPa, 200–400% elongation). This reduces the risk of film tearing during use.
Operational advice: Use ASTM D412 testing to compare tear resistance. Xin Gen supports customized thickness and hardness—a crucial advantage when your product requires specific grip or flexibility.
3. Chemical resistance
Urine contains urea, ammonia, and salts—a hostile environment for many polymers. TPU’s chemical structure resists hydrolysis and enzymatic degradation better than polyolefins.
Data point: Accelerated aging tests (at 70°C and 95% humidity for 28 days) show TPU retains 90%+ tensile strength, while PE films lose up to 40% strength under the same conditions. This translates to longer shelf life and reliability.
My thought: Many brands sacrifice material quality for a 5–10% cost reduction. But in a market where patient safety and brand trust are paramount, those savings are a false economy.
The Medical-Grade Advantage: Why Certification Matters
Incontinence products are classified as medical devices in many regions. TPU films used in these products must meet strict biocompatibility standards.
Certification reality:
Xin Gen’s products are ISO 9001:2015 and OHSAS 18001:2007 certified, with third-party approval from SGS, ROHS, REACH, FDA, and EU 10/2011. This is not optional—it’s mandatory for market access in Europe, the US, and much of Asia.
Specific requirement:
ISO 10993-5 cytotoxicity testing: Must show no cell death after 24-hour contact.
ISO 10993-10 sensitization testing: No allergic response in test animals.
Operational advice: Always request certificates for raw materials. Xin Gen’s factory includes a dedicated R&D center and product laboratory to ensure quality.
A real-world example:
A Brazilian manufacturer approached Xin Gen for TPU film used in a new incontinence product line. They needed a film that would bond securely to nonwoven fabric during lamination. Xin Gen’s high-adhesion TPU film, originally developed for bulletproof glass lamination, was adapted—and the product passed pilot production successfully.
My view: The cross-industry experience Xin Gen brings—from automotive paint protection to medical catheters—gives them a unique understanding of adhesion, clarity, and durability that pure-play incontinence film suppliers lack.
The Cost-Benefit Math: Is TPU Worth It?
Let’s break it down with real cost data.
Raw material cost: TPU film typically costs 2–3x more per square meter than PE film.
Production process: TPU requires precise extrusion temperatures and cooling, adding 10–15% to processing costs.
Value proposition: Premium incontinence products command 40–60% higher retail prices. A study by MarketResearch.com showed that 68% of consumers would pay more for products that reduce skin irritation.
The math:
If a PE-backed diaper costs $0.15 to produce and sells for $0.50, gross margin is 70%. A TPU-backed diaper costing $0.25 to produce and selling for $0.80 yields 69% margin—nearly identical, but with lower risk of returns and higher customer satisfaction.
My conclusion: The higher cost of TPU is offset by premium pricing and reduced liability. For care facilities, the savings from fewer skin treatment interventions ($200–$1000 per case) make the switch a no-brainer.
Practical Guide: How to Evaluate TPU Films for Incontinence Products
Based on industry experience, here’s a checklist:
1. Test for breathability
Request data on MVTR, hydrostatic head resistance (AATCC 127), and air permeability. Aim for MVTR >1000 g/m²/24h with hydrostatic head >500 mm.
2. Check adhesion compatibility
If laminating with nonwovens, test peel strength at various temperatures and humidity levels. Xin Gen’s sampling service allows low-cost trials with just 400mm width—perfect for initial evaluation.
3. Verify regulatory compliance
Ensure ISO 10993, FDA, and EU MDR certifications. Without these, you cannot sell in regulated markets.
4. Assess color and transparency
Some TPU films yellow under UV exposure. Ask for accelerated weathering test data (ASTM G154). For medical devices, optical clarity may be important for visual inspection.
5. Evaluate supplier lead time
Xin Gen’s Shanghai factory covers 6,000+ sqm with sales branches in Shenzhen and Los Angeles. Their fast sampling system helps shorten development cycles—critical in a competitive market.
Final Word
Incontinence care is evolving. Users and healthcare providers demand better performance—not just in absorbency, but in skin health, durability, and comfort. TPU films are not a luxury; they are a necessity for premium product positioning.
Companies like Xin Gen Tech, with 15 years of TPU R&D and a global footprint, offer the technical depth to make that transition seamless. The upfront investment in better materials pays dividends in market share and patient outcomes.
The question isn’t whether TPU films are worth it. The question is: can you afford not to use them?
