<p>Inflatable body comprises a first outer layer, a second outer layer, and an intermediate layer (1) arranged between the outer layers, where each layers are made of a sheet material. The first outer layer comprises a first inner surface made of a thermoplastic material, facing the second outer layer, and the second outer layer comprises a second inner surface made of a thermoplastic material, facing the first outer layer. The intermediate layer has a first surface facing the first outer layer, and a second surface facing the second outer layer. The first surface has first welding portion (21). Inflatable body comprises a first outer layer, a second outer layer, and an intermediate layer (1) arranged between the outer layers, where each layers are made of a sheet material. The first outer layer comprises a first inner surface made of a thermoplastic material, facing the second outer layer, and the second outer layer comprises a second inner surface made of a thermoplastic material, facing the first outer layer. The intermediate layer has a first surface facing the first outer layer, and a second surface facing the second outer layer. The first surface in a region has a first welding portion (21) made of thermoplastic material, and the second surface in a region comprises second weld portion made of thermoplastic material. The first-and second weld portions are arranged such that portions of the second surface opposite to the first welding portions are free from thermoplastic material, and portions of the first surface opposite to the second welding portions are free from thermoplastic material. The first inner surface in the region of the first weld portions are welded with the first surface and the second inner surface in the area of the second weld portions are welded with the second surface.</p> |
