Abstract
The invention relates to a side-sealed vacuum insulation panel. The side-sealed vacuum insulation panel is formed by utilizing a barrier film to coat and seal filled core materials. During sealing, the barrier film forms a back seal and the two side seals, and back seal is disposed on the upper surface of the vacuum insulation panel, and the two side seals are arranged on the upper surface or the lower surface of the vacuum insulation panel. During construction of the vacuum insulation panels with the side edge seals, the abutted seams among the panels are small, and due to the fact that the two side seals are arranged on the upper surface and/or the lower surface of the vacuum insulation panel, a user does not need to bond the heat-sealed side seals to a vacuum insulation panel body, large-area overlap of the barrier film of the abutted seams can be avoided, and good heat insulation performance and attractiveness in appearance can be obtained.
