Detailed Description

It should be noted that, under the condition of no conflict, the embodiments of the present embodiments and features in the embodiments may be combined with each other, and the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model, and obviously, the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the present embodiment aims to solve the waterproof problem of the conventional carton package and increase the waterproof effect. When the paper board is wet or wet, the paper board can not be softened, can be reused, can be taken under the sun for sun drying, and can not lose the original texture and hardness. In view of the above, there is provided an ultra-toughness kraft board, comprising a main body 4, wherein the main body 4 comprises an outer layer 1, the bottom of the outer layer 1 is fixedly connected with a middle layer 2, a plurality of engagement grooves 11 are uniformly formed on the lower surface of the outer layer 1, and the lower surface of the outer layer 1 is formed into a corrugated structure by a plurality of engagement grooves 11; further comprises:

the upper surface of the middle layer 2 is meshed with the lower surface of the outer layer 1, and a buffer cavity 12 is formed in a protruding part of the corrugated structure;

and the top of the inner layer 3 is connected with the bottom of the middle layer 2 in an adhesive way.

The engagement grooves 11 are provided with evenly distributed protrusions which are engaged with the depressions of the middle layer 2. Wherein the engagement groove 11 is provided in a wave shape such that a space in which the buffer chamber 12 is provided is left in the convex portion thereof.

In order to prevent the paperboard from being severely deformed when the paperboard is subjected to external force, the use of the paperboard is greatly influenced, and the buffer cavity 12 is filled with a buffer material, preferably a foam ball. The foam ball has the advantages of small volume, light weight, easy obtainment of materials and the like, when the foam ball is used as a buffer material, the foam ball can be filled in a large amount in the buffer cavity due to the characteristic of small volume, so that a large amount of gaps are generated in the buffer cavity, and when the paperboard receives external force, the large amount of foam balls can disperse the force born by the paperboard, thereby achieving the purpose of shock resistance and shock absorption; due to the characteristic of light weight, when a large number of foam balls are placed in the buffer cavity, the influence of the weight of the foam balls on the weight of the paperboard is negligible, so that the paperboard has the advantages of high impact resistance and shock absorption performance, light weight and convenience; the foam ball is low in cost and can be obtained in a large amount due to the characteristic of easily available materials, so that the cost of the paperboard is reduced.

The upper surface of the middle layer 2 is connected with the lower surface of the outer layer 1 in an adhesive way, so that the toughness of the paperboard is further enhanced. In order to give the outer layer of the board a certain waterproof and tough function, the outer layer 1 is coated with a hydrophobic layer, preferably with molten paraffin.

The hydrophobic layer coated on the outer layer 1 of the paperboard forms a state that water drops on the lotus leaves when the paperboard is subjected to water showering, and the water becomes water drops to slide down without penetrating into the interior of the paperboard. The molten paraffin has low cost, is suitable for packaging dry powdery articles, particularly powder which is easy to agglomerate after absorbing water, is also suitable for packaging goods which often enter and exit a refrigerator, and is easy to coagulate on the wall of the refrigerator after being taken out from the refrigerator. The paper board after the hydrophobic processing can not obviously reduce the compressive strength before dew evaporates, and can effectively protect articles, so that the paper board has ideal waterproof effect. When the paper board is wet or wet, the paper board can not be softened and can be reused; the middle layer 2 is made of wood pulp fiber, so that the cost of the paperboard is reduced. The inner layer 3 of the paperboard is made of cloth paper, and a plurality of soft pads 31 are fixedly arranged on the lower surface of the inner layer 3. The paper material has beautiful characteristics, so that the paperboard has the functional characteristic of being used as a packaging box of high-grade products.

When the paperboard is particularly used, the main body 4 of the kraft board is formed by mutually bonding and connecting the outer layer 1, the middle layer 2 and the inner layer 3, the lower surface of the middle layer is of a wavy structure, the bulge of the middle layer 2 is provided with the buffer cavity 12, foam pellets are filled in the buffer cavity 12, and the foam pellets have the advantages of small volume, light weight, easy obtainment of materials and the like; due to the characteristic of light weight, when a large number of foam balls are placed in the buffer cavity, the influence of the weight of the foam balls on the weight of the paperboard is negligible, so that the paperboard has the advantages of high impact resistance and shock absorption performance, light weight and convenience; the foam ball is low in cost and can be obtained in a large amount due to the characteristic of easily available materials, so that the cost of the paperboard is reduced. The upper surface of the middle layer 2 is connected with the lower surface of the outer layer 1 in an adhesive way, so that the toughness of the paperboard is further enhanced. In order to give the outer layer of the board a certain waterproof and tough function, the outer layer 1 is coated with a hydrophobic layer, preferably with molten paraffin. The hydrophobic layer coated on the outer layer 1 of the paperboard forms a state that water drops on lotus leaves when the paperboard is subjected to water spraying, the water changes into water drops to slide down, the pressure resistance of the paperboard which is subjected to hydrophobic processing and is not permeated into the paperboard is not obviously reduced before dew evaporates, articles can be effectively protected, and the paperboard has ideal waterproof effect. The cardboard will not soften when it encounters water or becomes wet. The inner layer 3 of the paperboard is made of cloth paper, and a plurality of soft pads 31 are fixedly arranged on the lower surface of the inner layer 3. The aesthetic property of the cloth paper material and the softness of the soft pad enable the paperboard to have the functional characteristic of being used as a packaging box of high-grade products.
