Optical Grade TPU Film

This is the category for jobs where visual clarity is non-negotiable. Clear TPU film and transparent TPU film in this line are built for low haze and high light transmittance, so whatever sits behind the film — a display, a medical sample, a printed layer — stays undistorted.

What sets it apart:

• Aliphatic TPU film formulations, which hold their clarity and resist yellowing over time far better than standard aromatic TPU film
• Consistent optical performance across the full width and length of the roll
• Soft TPU film handling that stays workable through downstream converting

Typical fit: medical imaging components, optical windows, and any build where a flexible transparent TPU film has to keep its clarity through repeated handling or sterilization.

UV Resistant TPU Film

Standard plastic films break down under sun exposure — they yellow, go brittle, lose strength. UV resistant TPU film is formulated to hold up under long-term outdoor exposure, and it outperforms PVC or PET film here by a wide margin.

Where it gets used:

• Outdoor equipment and furniture, where a flexible waterproof TPU film needs to survive season after season
• Protective surface layers on signage, awnings, outdoor structures
• Semi-transparent and colored TPU film variants that need UV stability alongside visual performance

Polyether TPU film formulations are built mainly for hydrolysis resistance — a different property, but manufacturers often combine both resistance profiles into one formulation for products that face both moisture and sun.

Medical Grade TPU Film

Medical TPU film gets held to a different standard. This tpu medical-grade film series is formulated and tested for biocompatibility, purity, and reliable barrier performance, produced and documented against ISO 10993 biocompatibility standards.

What it’s built for:

• Medical device bladders and fluid-handling components
• IV solution bags and other flexible medical containers
• Wound care and skin-contact barrier layers, where non-toxic composition and gas barrier performance both matter

Direct or indirect patient contact means batch-to-batch consistency — thickness, purity, weldability — isn’t optional. Every batch of medical-grade TPU film ships with compliance documentation attached.

TPU Hot Melt and Adhesive Film

A different category entirely: TPU hot melt film and TPU adhesive film work as a bonding medium, not a surface layer. Heat activates the film and fuses fabric, leather, or foam together without stitching.

This covers garment TPU film for seam sealing and lamination, TPU film for shoes — leather upper bonding especially — and mattress TPU film used in quilted or laminated bedding builds. These applications flex repeatedly after bonding, so elasticity and bond strength retention over time are what actually determine the right pick.

Picking the Right TPU Film

A few variables decide the right film for a given job:

• Thickness and roll width — thinner films for medical and optical work, heavier gauge for protective and industrial applications
• Formulation — aliphatic vs. standard polyester or polyether TPU film, depending on whether UV stability, hydrolysis resistance, or general flexibility is the priority
• Compliance — medical-grade documentation, REACH/RoHS compliance, or a specific HS code for import/export
• Processing fit — RF welding, heat sealing, lamination, or hot melt bonding

Xianglong supplies TPU film manufacturers, converters, and product developers with consistent rolls across clear, UV-resistant, and medical-grade formulations, with full customization on thickness, width, and surface finish. As a direct TPU film manufacturer based in China, we handle both bulk roll orders and smaller trial quantities for product development and testing.

A flexible transparent TPU film for optical work, a UV resistant TPU film for outdoor products, a medical-grade TPU film for healthcare devices — each one needs its formulation and processing profile matched to the actual end-use environment. That match is what determines how the film performs once it’s in the field.
