气模闭气布料是气模产品中实现气体密封的核心材料，常见类型以PVC涂层布为主。该布料以聚酯纤维为基布，表面涂覆PVC材料形成复合结构，兼具高强度与高气密性，能有效防止气体泄漏，确保气模结构的稳定性和安全性，在各类充气场景中发挥关键作用。

Airproof fabric is the core material for achieving gas sealing in air mold products, and the common type is mainly PVC coated fabric. This fabric is made of polyester fiber as the base fabric and coated with PVC material on the surface to form a composite structure, which combines high strength and high airtightness, effectively preventing gas leakage, ensuring the stability and safety of the gas mold structure, and playing a key role in various inflation scenarios.
