[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] Figure 1 This is a schematic diagram of the structure of a paper cushioning lining for carton packaging according to the present invention; Figure 2 This is a schematic diagram of the front and rear side structures of the paper cushioning liner used for carton packaging in the utility model; Figure 3 The utility model is a schematic diagram of the exploded structure of the paper cushioning liner used for carton packaging.

[0014] See Figure 1 、 Figure 2 and Figure 3 The paper cushioning lining for carton packaging provided by the present invention includes two pairs of parallel trapezoidal cardboards 1, the planes where the longer bottom edges of each pair of trapezoidal cardboards 1 are located are aligned and a first kraft paper connecting piece 2 is provided, the planes where the shorter bottom edges of the two pairs of trapezoidal cardboards 1 are located are aligned and a second kraft paper connecting piece 3 is provided, the second kraft paper connecting piece 3 is provided on the planes where the top and bottom of the trapezoidal cardboards 1 are located, the length of the first kraft paper connecting piece 2 is greater than the length of the second kraft paper connecting piece 3, the outer edges of the trapezoidal cardboards 1 are aligned with the outer edges of the first kraft paper connecting piece 2 to form a sealed edge 4 to prevent the lining from cracking and falling apart.

[0015] The paper cushioning lining for carton packaging provided by this utility model comprises a trapezoidal paperboard 1 formed by extending and arranging isosceles trapezoids. Each pair of parallel trapezoidal paperboards 1 is aligned and spliced ​​to form a regular hexagonal cavity, providing improved support. The thickness of the trapezoidal paperboard 1 is greater than that of the first kraft paper connecting sheet 2, resulting in smoother and flatter top and bottom surfaces.

[0016] The paper cushioning lining for carton packaging provided by the present invention is easy to manufacture. Preferably, the trapezoidal paperboard 1 and the first kraft paper connecting piece 2 are connected by adhesive, and the second kraft paper connecting piece 3 and the trapezoidal paperboard 1 are connected by adhesive to complete the manufacture.

[0017] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make slight modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
