The heat sealing process of disposable power inflatable sterile medical heating blanket

  The material and heat sealing process of the disposable power inflatable sterile medical heating blanket are the key factors for achieving its functions and ensuring safety. The following is a detailed introduction for you:

Material
• Polypropylene Non-woven Fabric Combined with Polyethylene Film:
This is a common material combination. Polypropylene non-woven fabric offers softness, breathability, non-toxicity, and odorlessness, providing patients with a comfortable touch and reducing skin irritation. The polyethylene film boasts excellent sealing and barrier properties, effectively preventing heat loss and ensuring the warming blanket’s thermal insulation performance. The combination of these two materials leverages their respective strengths while meeting the diverse requirements for medical-use warming blankets.

• TPU (Thermoplastic Polyurethane) Material:
TPU is ozone-resistant, low-temperature-resistant, acid/alkali-resistant, and corrosion-resistant, with a soft surface that allows folding, rolling, cleaning, and sterilization. Warming blankets made of TPU adapt to various environments and operational needs while ensuring durability and hygiene.

Heat-Sealing Process
• Heat-Sealing Procedure:
The process typically involves bonding polypropylene non-woven fabric and polyethylene film using heat-sealing equipment. During heat-sealing, high temperatures melt the molecular surface of the materials, which are then fused under pressure to form a strong, sealed structure for the warming blanket.

• Advantages of Heat-Sealing:
◦ Ensured Sealing Performance: Precise heat-sealing prevents air leakage after inflation, ensuring efficient circulation of warm air within the blanket for optimal heating.
◦ Enhanced Strength: Heat-sealed blankets exhibit high durability, resisting pressure and tension during use to minimize damage, thereby ensuring reliability and safety.
◦ Guaranteed Sterility: Heat-sealing is typically conducted in a sterile production environment to prevent contamination, meeting requirements for disposable sterile medical products.
