What are the applications of hot melt TPU film in the medical and health fields?

Hot-melt TPU films are increasingly being used in the medical and health field, mainly due to their physical properties and safety. Generally speaking, hot-melt TPU films have some major applications in these fields:

1. Medical films (wound dressings)
Hot-melt TPU films are often used to make medical wound dressings, especially film materials used to cover wounds. These films have good breathability and waterproofness, which helps keep wounds dry and prevent infection without affecting the healing process of wounds. TPU films also have good flexibility and comfort, and can adapt to different body shapes to improve wearing comfort.
Advantages:
Breathability: It helps to discharge moisture from the wound surface and avoid the growth of mold and bacteria on the wound surface.
Waterproofness: It effectively prevents external moisture and bacteria from entering the wound.
Light transmittance: It is convenient to observe the wound condition.

2. Infusion tubes and catheters
TPU films are widely used in medical catheters, infusion tubes, suction tubes and other medical devices. Due to its good biocompatibility and high mechanical strength, hot-melt TPU films are often used as protective films on the outer layer of catheters. These catheters need to be in contact with the human body for a long time, and the softness and non-toxicity of TPU film can meet their standards.
Advantages:
Softness: Improve comfort and reduce patient discomfort.
Durability: High-strength TPU film can withstand long-term use.
Antibacterial: Reduce the risk of bacterial growth on the outer layer of the catheter.

3. Surgical film
During surgery, TPU film is often used as a surgical film or cover to help seal the surgical area and prevent external bacteria from entering. Hot-melt TPU film has good transparency, allowing doctors to clearly see the surgical area, while its sealing performance effectively reduces the risk of infection.
Advantages:
High transparency: Provides a clear view to help doctors operate.
Strong sealing: Effectively prevents bacteria or contaminants from entering during surgery.
Non-irritating: No irritation to the skin and human body, suitable for long-term contact.

4. Respiratory masks and protective clothing
Hot-melt TPU film can also be used to make medical respiratory masks, isolation gowns and protective clothing. Because TPU film has good wear resistance, UV resistance and waterproof properties, it can provide effective protection in medical environments. TPU film in masks can usually resist the invasion of harmful substances such as bacteria and viruses.
Advantages:
Waterproof and chemical resistance: Effectively prevent liquid leakage or contamination.
Comfort: The film is soft and suitable for long-term contact with the skin.
Anti-ultraviolet: Extend the service life and is suitable for a variety of medical protective equipment.

5. Implanted device protection
For some implanted devices (such as pacemakers, artificial joints, etc.), hot-melt TPU film can be used to protect the device from external contamination or damage. The excellent mechanical strength, impact resistance and high temperature resistance of TPU film make it very suitable for the outer layer protection of medical equipment.
Advantages:
High temperature and corrosion resistance: Ensure long-term protection of the device in extreme environments.
High strength: Improve the impact resistance of the device.
Flexibility: Provide better adaptability and comfort.

6. Medical delivery systems (such as drug delivery belts, drug sustained-release membranes)
Hot-melt TPU films can also be used in medical delivery systems, such as drug sustained-release membranes or conveyor belts. These films usually have precise drug release control capabilities and can effectively deliver drugs to designated locations. The biocompatibility of TPU films makes them suitable for devices that come into contact with the human body for a long time.
Advantages:
Sustained-release properties: Helps to accurately control the release rate of drugs.
Biocompatibility: Safe for contact with the human body and will not cause allergic reactions.

7. Medical packaging protection
Hot-melt TPU films can also be used as packaging materials for medical devices and drugs. Since TPU films have excellent moisture resistance, waterproofness and breathability, they play an important role in protecting medical devices and drugs from environmental pollution and external damage.
Advantages:
Waterproofness: Effectively protect medical products in the package from moisture.
Breathability: Maintain appropriate humidity in the package and extend the shelf life of drugs or devices.

8. Medical glove lining
Hot-melt TPU films can also be used as lining materials for medical gloves. Due to its excellent elasticity, abrasion resistance and good skin adaptability, TPU film is an ideal choice in glove production.
Advantages:
Comfort: Gentle contact with skin, reducing allergic reactions.
High strength: Provides additional abrasion resistance and protection.
