Detailed Description
The present invention will be further explained below.
A flexible thermal insulation bag comprises a bag body 1 and a sealing connecting part 2, wherein the bag body 1 is made of flexible materials, the interior of the bag body is of a cavity structure, and the top of the bag body 1 is provided with a seal; the seal is connected with a seal connecting part 2 for opening or sealing the bag body 1; the sealing connecting part 2 is a pair of sealing strip structures 3 with a certain length and meshed with the sawteeth, and the sealing strip structures 3 are symmetrically arranged at two ends of the seal; wherein the sealing strip structure 3 is provided with a movable unit 4 for saw tooth engagement or spreading.
The bag body 1 is provided with a vent valve 5, and the vent valve 5 is connected with a vent valve cover 6 through threads; the vent valve 5 can be connected to a vacuum pump.
The bag body 1 is a three-layer structure composite bag body and consists of a surface layer 7, a middle core material 8 and an innermost layer 9, wherein the thickness of the surface layer 7 is set to be 35-50 mu m, and the thickness of the innermost layer 9 is set to be 25-75 mu m; the bag body 1 is set to be any one of square, round, diamond, trapezoid, fan-shaped, star-shaped and irregular shapes.
The surface layer 7 and the innermost layer 9 are of flexible material structures and are independently set to be any one of a kraft paper layer and an aluminum-plastic composite film layer, and the decorative layer is adhered to the surface layer 7.
