Technical Field

The utility model relates to a cardboard technical field, concretely relates to corrugated container board.

Background

Corrugated cardboard is a composite cardboard formed by bonding one or more layers of corrugated paper between a plurality of layers of paper or cardboard, and is mostly used for manufacturing corrugated cartons. The corrugated board has the characteristics of low price, easy processing, good buffering and pressure resistance and the like, and is widely applied to product packaging. It also presents problems in some specific configurations and usage scenarios. For example, when the corrugated case is used for containing liquid or other products which can spread outwards, the expansion and bulging of the corrugated case can occur; the condition that the hand hole tears can also be caused because cardboard intensity is not good when the side of carton is opened the hand hole. It is therefore necessary to consider improvements in the structure of corrugated cardboard.

Another common problem is that when the carton body is provided with an easily openable tear line, it tends to break off midway through the pull. In order to solve the problem that the tear line cannot be opened well, a plastic film tape is stuck on the inner surface of a paperboard by using special equipment after the paperboard is subjected to die cutting in the existing market. The production method needs to process the corrugated board again after the corrugated board is produced, and is time-consuming and relatively complex in process.

Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Corrugated board is a common material used in product packaging. Corrugated board typically comprises at least one layer of face paper and at least one layer of medium paper. The shape of the corrugation is divided into V shape, U shape and UV shape according to the size of the corrugation arc, and the shape of the corrugation plays a decisive role in the compressive strength of the corrugated board. In the production of corrugated medium paper, the corrugated medium paper is processed by a corrugating machine, and the medium paper is corrugated by a corrugating roller heated to 160-180 ℃ to form corrugated paper. The flute direction of the corrugated medium paper refers to the transverse direction of the corrugated board which is perpendicular to the mechanical direction of the corrugated board. Corrugated paper boards can be divided into double-layer, three-layer, five-layer and seven-layer corrugated paper boards according to different material layers. The utility model discloses set up one or many atress areas of parallel arrangement inside corrugated container board, have simplified technology, can strengthen cardboard intensity simultaneously, or provide the effect that good unpacking was experienced.

The material of the force-bearing belt can be selected from PE (polyethylene), OPE (oxidized polyethylene), PP (polypropylene), BOPP (biaxially oriented polypropylene), PA (nylon) and glass fiber. The above are only preferred types of materials, and the material of the force-receiving belt is not limited to the listed types of materials. Different materials have different purposes, and suitable materials can be selected according to application scenes.

The width of the stress belt is referred to the width of the easy-to-tear belt on the market, and the general width ranges from 3mm to 20mm, but the invention is not limited thereto.

As shown in fig. 1, the corrugated cardboard is a three-layer corrugated cardboard including an outer face paper 1, an inner face paper 2, and a corrugated medium paper 3 between the inner and outer face papers. Three-ply corrugated board is often used to package lighter weight cartons and is used in the largest amount in corrugated board. A stress belt 4 is arranged between the external surface paper 1 and the corrugated medium paper 3. In the production of corrugated cardboard, the face paper and the corrugated medium paper are bonded to each other by an adhesive. The stress belt coiled material is sandwiched between layers when different layers of paper are bonded through a corrugated board production line, and the stress belt 4 is fixed between the external surface paper 1 and the corrugated core paper 3 through the bonding force between the layers. The direction of the stress belt is vertical to the corrugation direction of the corrugated medium paper.

The force-bearing belt 4 may also be provided between the internal surface paper 2 and the corrugated medium paper 3 in parallel, as shown in fig. 2. At this time, the force receiving belt is sandwiched between the inner sheet 2 and the corrugated medium 3, and is fixed by the adhesive force between the layers.

The stress belt can also be arranged between the inner surface paper and the corrugated medium paper and between the outer surface paper and the corrugated medium paper.

As shown in fig. 3, the corrugated cardboard is a five-layer corrugated cardboard, and includes an outer surface paper 1, an inner surface paper 2, two corrugated medium papers 3 between the inner and outer surface papers, and an intermediate packing paper 5 between the two corrugated medium papers 3. Five-ply corrugated board has greater strength and is commonly used to package delicate goods which are heavier. The force-receiving belt 4 is disposed between the external face paper 1 and the corrugated medium paper 3. The production process is the same as that of the three-layer corrugated board.

As shown in fig. 4-6, the force-receiving belt 4 may also be disposed between the internal surface paper 2 and the corrugated medium 3 and/or between the intermediate packing paper 5 and the corrugated medium 3. If the corrugation directions of the two layers of corrugated medium paper are different, the direction of the stress belt is vertical to the corrugation direction of the nearest corrugated medium paper.

The corrugated board with the stress belt can be applied in various scenes and plays a positive role. For example, the stress belt is transversely designed around each side of the box body, so that the strength of the carton is enhanced, and the carton is prevented from expanding. Or for the carton with hand holes on the side surface, the stress belt is designed above the hand hole direction, and the purpose of increasing the strength of the hand holes and preventing the hand holes from being broken is achieved. Or can be used for tearing and opening the carton, and has the purpose of facilitating tearing.

The corrugated cardboard has various kinds and layers, and the above examples are only used to illustrate the technical solution of the present application, but not to limit the same. The technical scheme of the application can be applied to other types of corrugated boards on the market. That is, although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
