Multilayered super barrier sealing member for vacuum insulation materials having excellent gas barrier property

摘要

The present invention relates to a gas barrier property is excellent for multi -type super vacuum insulation barrier sealing member , and more specifically, the heat seal layer as the innermost layer , a barrier layer as the multilayer -type sealing member for the vacuum heat insulating material having a protective layer as the metal layer and the outermost protective layer comprising an inorganic oxide -deposited polyethylene terephthalate layer vacuum insulator relates to a sealing member for a multi-layer type super barrier . Vacuum heat insulator comprising a sealing member according to the present invention as a sheath material , it is the initial thermal insulation ability , as well as durability under long-term use , especially suitable as far excellent useful life of more than 30 years compared with the conventional construction of the product . ;
