Problems solved by technology

[0003] In the prior art, at present, the lining box mostly adopts the injection molding process, but this kind of method is complex in process and uses non-degradable plastics. If degradable plastics are used, the price is really expensive; or the one-piece folding inner liner is used, but this The stability of this kind of method is not good, the folding process consumes more manpower and material resources, and the shape is relatively single, which cannot meet the requirements of multi-type and complex-shaped linings

Embodiment 1

[0044] like figure 1 As shown, a kind of packing box lining includes upper layer cardboard 1, 3 layers of middle layer cardboard 2 and lower layer cardboard 3, upper layer cardboard 1, middle layer cardboard 2 and lower layer cardboard 3 are cardboards coated with polylactic acid, and the thickness of polylactic acid is 15-35mu; upper layer cardboard 1 and lower layer cardboard 3 are coated on one side, and middle layer cardboard 2 is coated on both sides; such as figure 2 and Image 6 , the solid line in the figure is the cutting line, the dotted line is the folding line, the shape and size of the upper layer cardboard 1 and the lower layer cardboard 3 are exactly the same, and there are side plates 4 connected to the four peripheries, and the side plates 4 can be folded into any angle; the upper layer cardboard 1 Die cut out the product shape, such as image 3 , Figure 4 and Figure 5 As shown, the middle-layer cardboard 2 includes a first middle-layer cardboard 201, a...

Embodiment 2

[0051] like Figure 7-10 As shown, a packing box lining includes an upper layer of cardboard 1, a middle layer of cardboard 2 and a lower layer of cardboard 3, the shape and size of the upper layer of cardboard 1 and the lower layer of cardboard 3 are exactly the same, and the four peripheries are connected with side panels 4, side The board 4 can be folded into any angle, the upper layer cardboard 1, the middle layer cardboard 2 and the lower layer cardboard 3 are cardboards coated with polylactic acid, the upper layer cardboard 1 and the lower layer cardboard 3 are coated on one side, the middle layer cardboard 2 is coated on both sides, The thickness of lactic acid is 15-35mu; as Figure 8-Figure 10 As shown, the solid line in the figure is the cutting line, and the dotted line is the folding line. The upper layer cardboard 1, the middle layer cardboard 2 and the lower layer cardboard 3 also include positioning holes 5; the upper layer cardboard 1 and the lower layer cardbo...

Abstract

The invention provides a packing box lining which comprises an upper-layer paperboard, a plurality of middle-layer paperboards and a plurality of lower-layer paperboards, and the upper-layer paperboard is subjected to die cutting to form a product shape; the middle-layer paperboard comprises a plurality of containing cavities capable of containing products and pressing parts. The lower-layer paperboard is subjected to die cutting according to the shape of the placing cavity; and the placing cavity is positioned between the upper-layer paperboard and the lower-layer paperboard and is bonded with the upper-layer paperboard and the lower-layer paperboard through the pressing part. The environment-friendly paper (paperboard coated with polylactic acid) is adopted as the raw material, and the national plastic-limited new standard is met; meanwhile, the lining box is prepared by compounding multiple layers of paperboards in a thermocompression bonding mode, the process is simpler compared with an integrated forming mode, and manpower and material resources are saved; and a multi-layer paper compounding mode is adopted, so that the stability of the lining box is higher, and the compression resistance and shock resistance are better.

Description

technical field [0001] The invention relates to the technical field of packaging boxes, in particular to an inner lining of a packaging box. Background technique [0002] In recent years, plastics have been widely used in people's daily life. According to statistics, the global plastic production capacity in 2018 was 360 million tons, and the production has increased by more than 20 times since 1964. It is expected that the global plastic production will double again in 2035. Statistics show that the main focus of global plastic production has shifted from developed economies such as Europe and the United States to Asia. Disposable plastic products are used in large quantities and have a low recycling rate, which have caused serious pollution to the soil and marine environment, brought irreparable damage to the ecological environment, and more seriously endangered human health. It has become a general consensus of the international community to control plastic pollution. I...
