What Is TPU Bio-Based Film?
TPU Bio-Based Film is a thermoplastic polyurethane film manufactured with a significant portion of renewable, plant-based raw materials — derived from sources such as corn starch, sugarcane, and castor oil. By replacing a portion of fossil-fuel-based feedstocks, our bio-based TPU film reduces carbon footprint by up to 40% while maintaining the mechanical performance of conventional TPU.
At Shanghai Functech Tech, we produce TPU Bio-Based Film in our 8,500 m² facility in Songjiang, Shanghai, equipped with three casting and extrusion lines. Available in bio-content from 20% to 90% (certified under USDA BioPreferred where applicable), in thicknesses from 0.02 mm to 1.5 mm, and widths up to 1,600 mm.

Frequently Asked Questions
Common questions about our TPU Bio-Based Film — your question not here? Contact us directly.
What exactly does “bio-based” mean for TPU film?
“Bio-based” means a portion of the film’s raw materials is derived from renewable plant sources — such as corn starch, sugarcane, or castor oil — rather than fossil fuels. The bio-content is verified by C14 analysis per ASTM D6866, which measures the proportion of modern (plant-based) carbon in the material. Our bio-content ranges from 20% to 90%, allowing you to balance sustainability targets with cost and performance requirements.
Is bio-based TPU film biodegradable?
Not necessarily — bio-based and biodegradable are two separate properties. Standard bio-based TPU grades are recyclable but not biodegradable (similar to conventional TPU). We also offer specialized biodegradable and compostable grades that break down under industrial composting conditions per ASTM D6400 / EN 13432, or in soil per ASTM D5988 for agricultural applications. Tell us your end-of-life requirement and we will recommend the right grade.
What biocompatibility certifications are available for medical applications?
Our medical grades are tested per ISO 10993-1 framework, including ISO 10993-5 (in vitro cytotoxicity), ISO 10993-10 (skin irritation and sensitization), and supporting physical/chemical characterization. We provide complete test reports and certificates that support your medical device registration (CE MDR, FDA 510(k)) for skin-contact and short-term contact applications. Extended biocompatibility testing for longer-contact applications can be arranged with accredited third-party labs.
How does bio-based TPU film compare to conventional TPU film in performance?
Our bio-based grades are formulated to achieve performance parity with conventional TPU — comparable tensile strength, elongation, tear resistance, and hydrolysis resistance. Bio-content above ~50% may slightly reduce some mechanical properties, which our R&D team balances through polymer blending and formulation optimization. For most applications — medical, packaging, textiles, and industrial — the performance difference is negligible while the sustainability gain is substantial.
What is the minimum order quantity (MOQ) for TPU Bio-Based Film?
Our standard MOQ is 1,000 linear meters per specification for standard grades, and 3,000 linear meters for custom bio-content formulations. For new product development, we offer low-volume trial runs from 200 linear meters. We also welcome pilot programs with scheduled scale-up milestones — allowing you to validate the material in your application before committing to large volumes.
Can you help us with regulatory documentation and certification?
Yes. Every order ships with a Certificate of Analysis (COA) and full compliance documentation. We provide REACH and RoHS declarations, FDA and EU food-contact documentation, ISO 10993 biocompatibility test reports for medical grades, and C14 bio-content verification (ASTM D6866). We can also arrange third-party certification (USDA BioPreferred, compostability, etc.) and support your submission with the required technical documentation.
