<p>The invention relates to a flexible multi-layer material that can be used in particular for an inflatable balloon casing, a blimp, an airbag, a sail, a flexible solar cell, or a flexible antenna. At least one layer (11, 13) is provided, which is particularly made of ultra high molecular weight polyethylene (UHMWPE), or of ultra high molecular weight polypropylene (UHMWPP). The same is surrounded on each of the two sides by a layer, or a film (10, 12; 12, 14) made of polyethylene or polypropylene, and connected thereto, wherein the layers, or films (10-14) placed on top of each other can be connected to each other by means of heating. Such a material layer is lightweight and has high stability, or tear resistance, and a high modulus of elasticity.</p> |
