“ITS a tri-layered film incorporating Bio-based TPU, with a softer version on the exterior and a harder version on the interior. The key advantage of this design lies in the soft outer layer, which significantly enhances comfort for patients wearing dental appliances. This softness minimizes irritation and discomfort, making the appliance more pleasant to wear for extended periods. Simultaneously, the hard inner layer ensures the appliance maintains its structural integrity and applies the necessary force to keep it securely in place for its intended application. This innovative combination of materials not only improves patient comfort but also ensures the appliance functions effectively, providing the required support and stability. By utilizing Bio-TPU for both layers, we achieve an optimal balance between comfort and functionality, making this tri-layered film an ideal choice for dental applications where both patient satisfaction and appliance performance are paramount."
