TPU window opening film on disposable sterile non-woven surgical sheet

I. Definition and Function
TPU window film refers to a transparent film made of TPU (thermoplastic polyurethane) embedded into a disposable sterile non-woven surgical drape through specialized manufacturing processes. It is primarily used in specific areas during surgery, such as the incision site, to enable clear visualization of the surgical field for medical professionals while maintaining a sterile environment.

II. Material Characteristics

• TPU Material: TPU exhibits excellent elasticity, abrasion resistance, and chemical resistance, ensuring stable performance and structural integrity during surgical procedures.
• Transparency: The high clarity of the TPU window film allows surgeons to observe the surgical area with precision, enhancing procedural accuracy and safety.
• Sterility: The TPU window film undergoes rigorous sterilization during production to maintain a sterile state during surgery, minimizing infection risks.

III. Production Process

1. Raw Material Preparation: High-quality TPU film rolls and non-woven fabric are selected as raw materials to ensure product quality and performance.
2. Positioning and Fixation: The window film’s location is precisely determined on the non-woven surgical drape. A specialized heat press machine is used to thermally bond the TPU film to the non-woven fabric, ensuring airtight sealing and durability.
3. Quality Inspection: The fixed TPU window film undergoes thorough inspection to verify accurate positioning, secure bonding, and absence of air bubbles or wrinkles.
4. Sterilization: The entire surgical drape is sterilized to guarantee sterility.

IV. Application Scenarios
TPU window films are widely used in various surgical procedures, particularly in operations requiring clear visualization, such as orthopedic and neurosurgical surgeries. They provide unobstructed visibility while preserving the sterile field, significantly reducing the risk of surgical infections.
