Abstract

A vacuum insulation material includes a core material, and a wrapping member configured to cover the core material, the wrapping member provided with an outermost layer externally exposed, a barrier layer laminated beneath the outermost layer, and a thermal bonding layer disposed beneath the barrier layer and contacting the core material, wherein the barrier layer comprises at least one polyimide film, on which an inorganic layer is laminated. With the configuration, the wrapping member of the vacuum insulation material can be more resistant to high temperature such that the vacuum insulation material can be safe from the risk of deformation, resulting in enhancing reliability of insulation efficiency.
