NOVELTY - The gastight enclosure has a plastic carrier film with a thin gastight metallic coating for completely or partially enclosing an evacuated hollow space for sealing peripheral heat bridges in a gastight manner. The metallic coating is made of a metal with low thermal conductivity, where the metal is selected from a group consisting of titanium, high-grade steel, lead, tin, zinc, bismuth, tantalum, nickel, platinum, tungsten or alloys. The thermal conductivity of zinc is 110 watts per meter Kelvin (W/mK).    USE - Gastight enclosure for gastight peripheral sealing of edge areas of vacuum-insulating arrangements e.g. vacuum-insulated panel (VIP), vacuum-insulated glass (VIG) and/or edgeless vacuum-insulated composite system, which are utilized for forming a thermal insulated and/or sound proof insulation system e.g. building walls, basement walls, floor/stage walls, plate-shaped panels, door frames, window frames, door frames, window frames, roof walls, green houses, surface and pipe solar collectors, pipelines, pipe fittings, pipe armatures, valves, throttles, electric switch, stationary and portable heat/cold storage, cold/heat exchanger, boiler, filling systems/attachments for hot and cold medium, flow measuring units, power plant condenser, drive condenser, turbine condenser, steam condenser, downstream tower, gas tank, missile drive, electric turning shaft, generator turning shaft, heat decoupled turning shaft, transformer, drive power machine, heat power machine, stirling engine, burner, chimney, waste incinerating plant, waste incinerator, current superconductor, magnetic coil, heat pump, container/cover, food package, pharmaceutical package, medical package, thermo flask, dewar flask, ship housing, ship body, ship wall, ship carcass, aircraft housing, aircraft body, aircraft wall, aircraft carcass, rail vehicle housing, rail vehicle body, rail vehicle wall, rail vehicle carcass, land vehicle housing, land vehicle body, land vehicle wall, land vehicle carcass, cooling chambers, drive machines, refrigerators, cookware, kettle, baking device, melting pot, melting furnace, oven, helium tank, hydrogen tank, brake lines, pipelines, compressed air container, VIP angular elements, VIP edge elements, sound proof covering for power machines, refinery, chemical systems, nuclear fusion reactor, tokamak reactor, district heating pipeline, nuclear spin tomography, thermal treatment system, thermal shielding elements, heat protective clothing, heat protective shoes, diving suit and missile propellant (all claimed).    ADVANTAGE - The thin gastight metallic coating of the plastic carrier film completely or partially encloses the evacuated hollow space for sealing the peripheral heat bridges in a gastight manner, where the metallic coating is made of the metal with low thermal conductivity, thus reducing heat transfer of the metallic coating and/or increasing gas tightness of the enclosure, and hence increasing service life and/or utilization of economic filling material of the vacuum-insulating arrangements.
