断熱性は低下する。(21 Conventional Example and Problems There is a well-known heat insulating panel made by filling a plastic laminate container with a lightweight porous powder such as perlite and evacuating the inside to a vacuum. Conventionally, this plastic laminate container was used to maintain a vacuum. To achieve this, a gas barrier layer composed of aluminum foil with a thickness of 7 to 20 μm, stretched polyvinyl alcohol coated with aluminum, or ethylene-vinyl alcohol copolymer coated with aluminum is used. In the case of using aluminum foil, since the aluminum foil with high thermal conductivity is close to each other in the sealing part, when the panel is formed, the heat transfer from this sealing part can be ignored and disappears, and the overall Thermal insulation is reduced.

As the constituent material of the plastic laminate container, a film made of vinylidene chloride-vinyl chloride copolymer, which is excellent in both oxygen barrier and water vapor barrier properties, and aluminum vapor-deposited on at least one side is used.

Ａ〜８００Ａ程度の厚さが望ましい。The gas barrier layer lb is characterized by using a film made of a resin of a copolymer of tri, vinylidene chloride, and vinyl chloride having high density and highly crystalline molecular chains, and having a thickness of aluminum on at least one side. The thickness of aluminum vapor deposition has a great effect on the barrier properties against oxygen and water vapor, but if it is not 100λ or more, the effect will be small;
If it is more than 0OA, cracks are likely to occur, so 400
A thickness of approximately A to 800 A is desirable.
