Abstract

The utility model discloses a waterproof packing cardboard of high crushing resistance belongs to packing carton production technical field, and this kind of waterproof packing cardboard of high crushing resistance includes waterproof layer (1), first corrugated board layer (2), enhancement layer (3), second corrugated board layer (4) and bottom (5) from last to down in proper order, the flute height of first corrugated board layer (2) is lower than the flute height of second corrugated board layer (4). The waterproof packaging paperboard with high compressive resistance has high strength and strong compressive resistance, and also has a certain waterproof function, so that the service capacity and the service life of the packaging paperboard can be effectively improved.

Description

Waterproof packing paperboard with high pressure resistance

Technical Field

The utility model belongs to the technical field of the packing cardboard production, specifically, relate to a waterproof packing cardboard of high crushing resistance.

Background

The corrugated board is light in weight, has high mechanical strength, can bear certain pressure, is elastic and has high buffering effect, and is mainly used for manufacturing cartons, the sandwich of the cartons and the packing materials of other articles. The packaging paperboard can be made into liners or containers with various shapes and sizes according to requirements, and is simpler, more convenient and faster than plastic buffer materials; the coating is slightly influenced by temperature, has good light-shielding property, is not deteriorated by illumination, is generally slightly influenced by humidity, but is not suitable for long-term use in an environment with high humidity, and influences the strength of the coating. The packing paper board produced by the prior art has smaller pressure resistance, and the strength of the packing paper board is greatly reduced in rain or wet weather, so that the packing paper board cannot be normally used.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a waterproof packing cardboard of high crushing resistance, its intensity of this kind of waterproof packing cardboard of high crushing resistance is high, and crushing resistance is strong, but also has certain waterproof function, can effectively improve its service ability and life.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a waterproof packing cardboard of high crushing resistance, includes waterproof layer, first corrugated container board layer, enhancement layer, second corrugated container board layer and bottom from last to down in proper order, the flute height on first corrugated container board layer is lower than the flute height on second corrugated container board layer. The mode of overlapping two layers of corrugated boards is adopted, so that the compression resistance of the paper boards can be enhanced.

Further, the waterproof layer is composed of a degradable PE film, and the degradable PE film is composed of the following components in parts by mass: 30-40 parts of PBAT, 20-40 parts of chitosan and 30-40 parts of photosensitizer. The degradable PE film can be biodegraded and does not pollute the environment.

Further, the photosensitizer is benzophenone.

Further, the reinforcing layer is composed of a plant fiber layer, and the thickness of the plant fiber layer is 1-2.5 mm. The plant fiber layer has wide source and low price.

Further, the bottom layer is made of kraft paperboard. The kraft paperboard is tough, stiff and solid, has extremely high compressive strength and has good moisture resistance.

Further, reinforcing strips which are uniformly distributed are arranged among the corrugations of the second corrugated paperboard layer. The reinforcing strips can enhance the pressure resistance of the paperboard.

Further, the height of the corrugations of the first corrugated cardboard layer is 1.5-2.5 mm lower than that of the second corrugated cardboard layer.

Has the advantages that: compared with the prior art, the utility model has the advantages of it is following: the high-pressure-resistance waterproof packaging paperboard provided by the utility model adopts the degradable PE film as the waterproof film, can be biodegraded, and does not pollute the environment; the compression resistance of the corrugated board can be strengthened by adopting a mode of overlapping two corrugated boards; the reinforcing layer is adopted to enhance the compression resistance; the bottom layer adopts kraft liner board paper, has stronger compressive property, and also has certain waterproof nature.

Drawings

Fig. 1 is a structural diagram of a waterproof packaging board with high pressure resistance according to the present invention.

In the figure: 1 waterproof layer, 2 first corrugated board layers, 3 reinforcing layers, 4 second corrugated board layers, 5 bottom layers and 6 reinforcing strips.

Detailed Description

The invention will be further elucidated with reference to the drawings and the embodiments.

Examples

As shown in fig. 1, the waterproof packaging paper board with high pressure resistance comprises a waterproof layer 1, a first corrugated paper board layer 2, a reinforcing layer 3, a second corrugated paper board layer 4 and a bottom layer 5 in sequence from top to bottom, wherein the height of the corrugations of the first corrugated paper board layer 2 is 1.5-2.5 mm lower than that of the corrugations of the second corrugated paper board layer 4. The waterproof layer 1 is composed of a degradable PE film, and the degradable PE film is composed of the following components in parts by mass: 30-40 parts of PBAT, 20-40 parts of chitosan and 30-40 parts of a photosensitizer, wherein the photosensitizer is benzophenone. The reinforcing layer 3 is composed of a plant fiber layer, and the thickness of the plant fiber layer is 1-2.5 mm. The bottom layer 5 is made of kraft paperboard. Reinforcing strips 6 which are uniformly distributed are arranged among the corrugations of the second corrugated paperboard layer 4.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications can be made without departing from the principles of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
