Description

Packaging material

technical field

The utility model relates to the field of packaging, in particular to a packaging material with a shock-absorbing function.

Background technique

Most products need to be packaged after they are manufactured. Moreover, many electronic products need to take shock-absorbing measures during packaging to avoid product damage due to external force extrusion or collision during product handling and transportation.

At present, the shock-absorbing material used is EPS (also known as Styrofoam, Chinese full name: expandable polystyrene), and EPS is difficult to decompose under natural conditions, causing white pollution.

Utility model content

In view of this, it is necessary to provide a shock-absorbing and environmentally friendly packaging material.

A packaging material, which has a semi-open package structure, is composed of two layers from the outside to the inside, the outer layer is made of kraft paper, and the inner layer is made of honeycomb paperboard.

Preferably, a part of the inner wall of the packaging material formed by honeycomb paperboard is provided with a plate for protecting part of the surface of the product, and the coefficient of friction of the plate is smaller than that of the honeycomb paperboard.

Preferably, the board is made of EPE material.

Preferably, the kraft paper, the honeycomb paperboard and the board in the packaging material are fixed together by pasting.

Preferably, the packaging material is a hexahedron with one side open, and a plate for protecting part of the surface of the product is provided on one inner wall of the hexahedron, and the friction coefficient of the plate is smaller than that of the honeycomb paperboard.

A packaging material, comprising a rectangular first plate, on which a well-shaped indentation line is arranged, the indentation line divides the first plate into nine rectangular blocks, the material of the first plate is kraft paper, the The packaging material also includes a second board, the shape and size of the second board is the same as that of the first board after removing the four rectangles at the four corners, and the material of the second board is honeycomb paperboard.

Preferably, the creasing lines between the three rectangular blocks on two opposite sides of the first board are cut to form slits.

Preferably, the packaging material further includes a third plate, the third plate is rectangular, its shape and size are the same as a rectangular block in the middle of the side of the first plate, and the coefficient of friction of the third plate is less than Friction coefficient of honeycomb paperboard.

Preferably, the board is made of EPE material.

The materials used in this embodiment are relatively easy to decompose, thereby reducing environmental pollution, and can play a shock-absorbing role based on the honeycomb paperboard, and play a firm packaging role based on the kraft paper.

Detailed ways

Please refer to FIG. 1 to FIG. 3 , which are schematic structural diagrams of three boards forming the packaging material in a preferred embodiment. The packaging material includes a first board 10 , a second board 20 and a third board 30 . The first plate 10 is rectangular, and there is a well-shaped indentation line 102 on it. The indentation line 102 divides the first plate 10 into nine rectangular blocks 104 . The creasing line 102 between the three rectangular blocks 104 on opposite sides of the first sheet 10 is cut to form a slit 106 for folding the first sheet 10 . The material of the first plate 10 is kraft paper.

The second board 20 is in the shape of a cross, and its shape and size are the same as those of the first board 10 after removing the four rectangles 104 at the four corners. The material of the second plate 20 is honeycomb paperboard.

The third board 30 is rectangular, and its shape and size are the same as a middle rectangular block 104 on the side of the first board 10 . The material of the third plate 30 is EPE (pearl cotton).

Please refer to FIG. 4 , which is a perspective view of a packaging material 100 composed of three plates shown in FIGS. 1 to 3 . After removing the four rectangular blocks 104 on the four corners, the remaining areas are overlapped; then the first plate 10 is folded along the creasing line 102 on it to form a semi-open package structure; finally, the third plate 30 is pasted on one of the cuboids. On the inner wall, the packaging material 100 shown in FIG. 4 is obtained.

Please refer to FIG. 5 , which is a schematic diagram of the packaging material 100 shown in FIG. 4 when packaging the product 50 . The openings of the two packaging materials 100 are set opposite to each other, and the packaged product 50 is wrapped between the two packaging materials 100 . Please also refer to FIG. 6 , which is a schematic view of the product 50 shown in FIG. 5 after being packaged by the packaging material 100 . The two ends of the product 50 are accommodated in two half-open packaging materials 100 . The product 50 usually has a relatively important front panel 502. In order to prevent the front panel 502 from being scratched by the packaging material 100 during packaging and unpacking, the packaging material 100 is provided with a third board 30 with a friction coefficient smaller than the honeycomb paperboard. When packing, let the front panel 502 of the product 50 face the direction where the third plate 30 is located.

The materials used in this embodiment are relatively easy to decompose, thereby reducing the pollution to the environment, and can play a shock-absorbing effect based on the honeycomb cardboard, play a firm packaging role based on the kraft paper, and based on the fact that the friction coefficient is smaller than that of the honeycomb cardboard The third plate 30 made of EPE protects the surface of the product 50 that needs to be protected, and it is not necessary to arrange the third plate 30 on each inner wall of the packaging material 100 to reduce costs.
