Problems solved by technology
[0002] With the accelerated pace of life, people usually use various packaging boxes to carry the food they need for consumption when needed. Currently, the common packaging boxes on the market are usually made of paper or plastic. Before use, the food packaging boxes need to be removed from the Tear open at the opening, take out the food and eat it. Once it cannot be eaten at one time, the food that cannot be eaten will easily stick to dust when exposed to the air, pollute the food, and cause waste; Single-layer box wall structure, simple manufacturing process and low cost, but also has the disadvantage of poor thermal insulation performance. As a take-away food packaging box, if it does not have the function of thermal insulation, it will affect the taste of the food, which is not conducive to people's consumption

Embodiment Construction
[0010] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0011] Such as figure 1 The heat-insulating food packaging box shown includes a box cover 1 and a box body 2. A layer of heat-insulating layer 3 is laid on the bottom of the box body 2, and a layer of air-permeable sealing film 4 is pressed on the heat-insulating layer 3 to separate the heat-insulating material from the food. Prevent children or the elderly from eating by mistake. There is a viewing window 5 in the middle of the box cover 1 . Wherein, the visible window 5 is a PVC film.
[0012] Inspired by the above-mentioned ideal embodiment according to the present invention, through the above-mentioned description content, relevant workers can make vari...
