The application of TPU in the inner bladder airbag of eye massage devices and the heat sealing process

I. Introduction \ n \ nWith the continuous development of technology, the quality of our life has been significantly improved. In this digital age, eye health has become one of the focuses of people's attention. Eye massagers, as one type of health care products, have become increasingly popular among consumers. However, how to ensure the comfort and durability of products is a major challenge faced by manufacturers. Among them, the application of TPU(thermoplastic polyurethane) and the heat sealing process have played a crucial role.

2. Application of TPU in the inner liner airbag of the eye massager

Lightweight and high performance: TPU material has become an ideal choice for the inner liner airbag of the eye massager with its excellent lightweight performance and high strength toughness. It can not only ensure the comfort of the product during use, but also effectively relieve eye pressure and achieve the expected massage effect.

Good flexibility and wear resistance: TPU has good flexibility and can adaptively adjust according to the shape of the eye during the massage process, providing a more fitting massage experience. At the same time, its wear resistance also allows the product to remain in good condition after a period of use.

3. The importance of heat bonding process in TPU application
The heat bonding process is a process of heating and combining two or more materials together, which can form a permanent connection between the materials. In the manufacturing process of the inner liner airbag of the eye massager, the heat bonding process plays a vital role.
First of all, heat bonding can ensure the complete sealing between the airbag and the liner to prevent gas leakage, thereby ensuring the safety and effect of the massage process. Secondly, by precisely controlling the heat-sealing temperature, the TPU material can maintain its original physical properties after heating, meeting the use requirements of the eye massager.

IV. Conclusion
The application of TPU in the inner bladder airbag of the eye massager and the heat-sealing process provide us with a high-quality health care solution. With the advancement of technology, we look forward to more innovations and breakthroughs to bring consumers a more convenient, comfortable and efficient health care experience.
