Application of TPU film in air mattress production

The application of TPU film in the production of air mattresses is mainly reflected in the following aspects.

The first is the airtight layer material. The TPU membrane has excellent barrier properties and can effectively prevent air penetration. When it is attached to the inner layer of the mattress fabric, it can maintain the inflated state for a long time, reducing the trouble of frequent air replenishment and improving the user experience.

The second is welding processing. TPU material has good thermoplasticity and high-frequency welding properties. During the production process, the membrane material and fabric can be firmly combined through hot pressing or high-frequency heat sealing processes to form a uniformly sealed air chamber structure. The joints have high strength and are not prone to air leakage and cracking problems.

Another is the environmental advantage. Compared with traditional PVC materials, TPU does not contain plasticizers, has no odor, has low volatile organic compound emissions, is soft and skin-friendly, and is more suitable for sleep products that are in direct contact with the human body, especially for infants and people who are sensitive to odors.

In addition, the TPU film has outstanding wear resistance, folding resistance, low temperature resistance, and strong elastic recovery ability. It can withstand the extrusion deformation caused by repeated inflation and deflation and human body rolling, extending the service life of the mattress. Its hydrolysis and UV resistance also make the product more stable in humid environments.

From the perspective of development trends, as people pay more attention to healthy sleep and green materials, TPU film is gradually expanding its application share in the field of air mattresses and becoming an important choice for high-end products due to its advantages such as lightweight and recyclability.
