Claims

[Scope of Claim for Utility Model Registration] (1) A strip of composite plastic film made by combining materials with extremely different dielectric losses is brought together with the surfaces of the materials having low dielectric loss, and a gas flow is applied through a thermally bonded seal line. A composite film with the same composition is placed between the bag-forming films that match the material surfaces with large dielectric loss, and the outer periphery of each air chamber and the partition are sealed by high-frequency bonding. Independent airtight chambers can be created by pressurizing the materials facing each other with high dielectric loss and fusing them at the seal line, creating separate airtight chambers with an air inlet that functions as a check valve. gas bag. (2) A strip of composite plastic film made of materials with different thermal bonding temperatures is combined with the high thermal bonding temperature material side, and is connected to the gas inflow path and each airtight chamber by the high temperature thermal bonding seal line. A composite film with the same structure is placed between the bag-forming films with their low-fusion-temperature material surfaces aligned, and the outer periphery and partition of each airtight chamber are processed using a heat-sealing line for low-temperature thermal bonding. 2. The gas bag with continuous independent airtight chambers according to claim 1, wherein the low heat sealing materials facing each other are fused together at a heat seal line.
