Description

Technical Field

[0001] This utility model belongs to the field of kraft paper technology, specifically relating to a multi-layer composite high-strength kraft paper structure. Background Technology

[0002] Kraft paper is used as a packaging material. It has high strength and is usually yellowish-brown. Semi-bleached or fully bleached kraft pulp is light brown, cream, or white. Its basis weight is 80–120 g / m². Its breaking length is generally over 6000 m. It has very high tear strength, bursting energy, and dynamic strength. It is mostly produced in rolls, but also in sheets. It is made from sulfate softwood pulp, which is beaten and formed on a fourdrinier paper machine. It can be used for cement bags, envelopes, glued packaging, asphalt paper, cable protection paper, and insulating paper, among other things. The "waterproof kraft paper structure" disclosed in application number "CN202020235794.0" is also an increasingly mature technology. This utility model discloses a waterproof kraft paper structure, which relates to the field of kraft paper structures. It includes a first kraft paper layer and a second kraft paper layer, with an interlayer installed between the first and second kraft paper layers. The upper surface of the first kraft paper layer is coated with a waterproof film layer, and the lower surface of the second kraft paper layer is also coated with a waterproof film layer. The interlayer includes a first kraft paper clamp and a second kraft paper clamp. A rigid cardboard is glued between the first and second kraft paper clamps. A first positioning protrusion is evenly arranged on the top of the first kraft paper clamp, and a first groove is formed below the first kraft paper layer for the first positioning protrusion to fit with a gap. A second positioning protrusion is evenly arranged below the second kraft paper clamp, and a second groove is formed above the second kraft paper layer for the second positioning protrusion to fit with a gap. This design avoids problems caused by rain, water ingress, or damage during transportation.

[0003] Currently, the processing and preparation of this type of kraft paper is often quite complex, and it is not possible to perform further toughening operations on the kraft paper according to the actual use. As a result, the kraft paper itself is not stable enough during reprocessing, is easily damaged, and has insufficient strength, which is not conducive to waterproof packaging. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer composite high-strength kraft paper structure, aiming to solve the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bottom covering mechanism, wherein the bottom covering mechanism includes a lower kraft paper surface for covering and fixing, the lower kraft paper surface is made of two layers of waterproof cowhide embossed together, and the surface of the lower kraft paper surface is coated with a waterproof coating.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 7The present invention provides the following technical solution: a multi-layer composite high-strength kraft paper structure, including a bottom covering mechanism 1, the bottom covering mechanism 1 including a lower sealing kraft paper surface 11 for covering and fixing, the lower sealing kraft paper surface 11 is made of two layers of waterproof cowhide embossed, and the surface of the lower sealing kraft paper surface 11 is coated with a waterproof coating.

[0029] In this embodiment: the top surface of the lower kraft paper 11 is provided with a covering mesh 12, and the surface of the covering mesh 12 is provided with a toughening mesh 13.

[0030] The covering mesh 12 and toughening mesh 13 used are clearly more tough and more stable in tear resistance than traditional kraft paper covering.

[0031] In this embodiment: the surface of the toughened mesh 13 is covered with a plurality of control rings 14, and the top center of the plurality of control rings 14 is provided with a covering point 15.

[0032] Several control rings 14 are used as wrapping for the toughening structure, which, combined with the wrapping points 15, improves the strength of the kraft paper itself.

[0033] In this embodiment: the top surface of the toughening mesh 13 is covered with elastic waterproof nylon 16, the elastic waterproof nylon 16 is hollow inside, and the top center of the toughening mesh 13 is provided with an adjustment layer 17 for covering, the adjustment layer 17 is made of transparent material, and the adjustment layer 17 has a pre-embedded cavity 18 in the center.

[0034] The adjustment layer 17 is used to provide sufficient space for the encapsulation and filling of the elastic waterproof nylon 16.

[0035] In this embodiment: the cavity of the pre-embedded cavity 18 is filled with a placement mechanism 2;

[0036] The placement mechanism 2 includes a flexible mesh 21 filled inside the pre-embedded cavity 18. Several layers of diamond-shaped cowhide strips 22 are woven sequentially in the middle of the flexible mesh 21. The several layers of diamond-shaped cowhide strips 22 are sequentially sewn and arranged in the middle of the flexible mesh 21.

[0037] Several layers of diamond-shaped cowhide strips 22 are used to wrap and sew the covering structure layer by layer, improving the stability of the bottom wrapping position.

[0038] In this embodiment, a shock-absorbing ball 23 for shock absorption is reserved at the seam between several layers of diamond-shaped cowhide strips 22. The shock-absorbing ball 23 is diamond-shaped and covers the corresponding cavity of the diamond-shaped cowhide strip 22.

[0039] The cushioning and shock-absorbing ball 23 and the diamond-shaped cowhide strip 22 are used as the wrapping and fixing of the diamond-shaped cowhide strip 22.

[0040] In this embodiment: the top surface of the flexible mesh 21 is provided with a top sealing kraft paper surface 24 and a cushioning adhesive 25 is provided on the surface of the surface.

[0041] The purpose of using the top kraft paper surface 24 is to achieve the overall encapsulation of the kraft paper by covering the flexible grid 21.

[0042] In this embodiment, the upper kraft paper surface 24 and the lower kraft paper surface 11 are both sealed together.

[0043] The internal packaging provides strong stability.

[0044] In practical use, the first step is to prepare and produce the product according to the structure of kraft paper.

[0045] First, the kraft paper, namely the outermost waterproof layer of the lower kraft paper 11 and the upper kraft paper 24, is cut and the surface is coated with wax for waterproofing.

[0046] Then, the top layer of kraft paper 24 is automatically glued with cushioning adhesive 25. This adhesive is layered and bonded to ensure that connecting air columns that provide cushioning can be attached during sealing.

[0047] Then the internal interlayer is stacked in sequence according to the pre-embedded cavity 18 and the flexible mesh 21. The toughening mesh 13 and the control ring 14 on the surface are used to increase the strength of the kraft paper itself and avoid wear and tear when wrapping items. This is because the flexible mesh 21 is a special mesh in the middle. This special diamond-shaped kraft strip 22 can effectively increase the tensile deformation capacity of the overall kraft paper and prevent it from breaking.

[0048] Furthermore, depending on specific needs, if personnel want to utilize the cushioning properties of the paper itself, such as wrapping some fragile items, they can fill the bottom of the pre-embedded cavity 18 with a nitrogen-filled cushioning plastic bag. Although this increases the thickness of the kraft paper itself, it can act as a cushioning pad to more stably cover fragile items.

[0049] Moreover, for users, the toughness of the bottom kraft paper 11 is also important. Therefore, a control ring 14 was added, which has a honeycomb pattern in appearance. The honeycomb pattern itself has strong bottom-holding ability, and the waterproofing stage is based on the wax oil layer of the kraft paper itself.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
