Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in figure 1, a thermal-insulated antistatic film, including wearing layer 1 that from the top down is glued in proper order, antistatic layer 2, PET substrate layer 3, pressure-sensitive adhesive 4 and PET release film 5, PET substrate layer 3 with the adjacent side of pressure-sensitive adhesive 4 is the burnishing surface, PET substrate layer 3 with the adjacent one side of antistatic layer 2 is the corrugated surface, be provided with a plurality of resin particles 31 on the corrugated surface, resin particles 31 is hollow.
