Abstract

The utility model discloses a novel cardboard is used in packing, including the cardboard body, the back spraying of cardboard body has one deck polyurea, the utility model discloses a cardboard is used in packing is through spraying polyurea at its outside, and then reaches better anticorrosive, waterproof, wear resistance, and because has certain elasticity after the polyurea spraying shaping, and then the packing cardboard that makes has better support, when cutting off the performance, can have certain shock-absorbing capacity, further improves the guard action to packing the product.

Description

Novel paperboard for packaging

Technical Field

The utility model relates to the field of packaging technology, especially, relate to a novel cardboard is used to packing.

Background

The packaging of traditional products such as refrigerators, washing machines, air conditioners and the like is generally carried out by folding paper boards into box-packed structures, wherein the structures of the paper boards are generally that a layer of flat paper is arranged inside and outside, and the middle of the paper boards is corrugated paper. But because the waterproof, dampproof, wear resistance of cardboard is relatively poor, very easy breakage or meet water, meet the tide deformation in the handling, and then have certain damage hidden danger to the security of the product of packing.

SUMMERY OF THE UTILITY MODEL

Therefore, the to-be-solved technical problem of the utility model is to overcome the above-mentioned not enough that current cardboard packing exists, and then provide a novel cardboard for packing.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a novel packaging paperboard comprises a paperboard body, wherein a layer of polyurea is sprayed on the back surface of the paperboard body,

preferably, the spray thickness of the polyurea on the back of the paperboard body is 0.1-1.0 mm.

Preferably, the front surface of the paperboard body is sprayed with a layer of polyurea.

Preferably, the spray thickness of the polyurea on the front surface of the paperboard body is 0.1-1 mm.

Preferably, a layer of polyurea is sprayed on four side surfaces of the paperboard body respectively, and the polyurea sprayed on the four side surfaces of the paperboard body and the polyurea sprayed on the back surface of the paperboard body are of an integral structure.

Preferably, the thickness of the polyurea sprayed on the four sides of the paperboard body is 0.1-1 mm.

Preferably, the polyurea sprayed on the back, the front and the side of the paperboard body is of an integral structure, and the polyurea sprayed on the outer side of the paperboard body seals and covers the paperboard body.

The utility model has the advantages that:

the packaging paperboard of the utility model is coated with polyurea on the outer sides, so that the whole paperboard is wrapped by polyurea, thereby achieving better corrosion resistance, water resistance and wear resistance, and the packaging paperboard has certain elasticity after being coated and formed by polyurea, thereby having better supporting and separating performances and certain buffer performance, and further improving the protection effect on the packaged product; the tearing resistance, the water resistance and the recycling performance of the packaging paperboard sprayed with the polyurea are greatly improved, the pollution to the environment can be greatly reduced, the energy source of the paper mass is saved, and the packaging paperboard has better environmental protection performance; the polyurea can be formed by spraying, the processing is simple, and the manufacturing cost is lower.

Drawings

In order that the present invention may be more readily and clearly understood, reference is now made to the following detailed description of the invention taken in conjunction with the accompanying drawings, in which:

fig. 1 is a schematic structural view of the novel packaging paperboard of the present invention.

The reference numbers in the figures denote:

1-a paperboard body; 2,3,4, -polyurea.

Detailed Description

Referring to fig. 1, a novel packaging paperboard comprises a paperboard body 1, wherein a layer of polyurea 2 is sprayed on the back surface (in the present application, the back surface refers to the surface of the paperboard which leaks outside after being packaged) of the paperboard body 1, and the spraying thickness of the polyurea 2 on the back surface of the paperboard body 1 is 0.1-1.0 mm; the front surface of the paperboard body 1 is coated with a layer of polyurea 3, and the coating thickness of the polyurea on the front surface of the paperboard body 1 (in the application, the front surface of the paperboard refers to the surface which is positioned at the inner side of a packaging cavity after being packaged) is 0.1-1 mm; a layer of polyurea 4 is respectively sprayed on four side surfaces of the paperboard body 1, and the thickness of the polyurea sprayed on the four side surfaces of the paperboard body 1 is 0.1-1 mm; polyurea sprayed on four side surfaces of the paperboard body 1 and polyurea sprayed on the back surface and the front surface of the paperboard body are of an integral structure, so that the paperboard body 1 is sealed and coated. The packaging paperboard of the utility model is coated with polyurea on the outer sides, so that the whole paperboard is wrapped by polyurea, thereby achieving better corrosion resistance, water resistance and wear resistance, and the packaging paperboard has certain elasticity after being coated and formed by polyurea, thereby having better supporting and separating performances and certain buffer performance, and further improving the protection effect on the packaged product; the tearing resistance, the water resistance and the recycling performance of the packaging paperboard sprayed with the polyurea are greatly improved, the pollution to the environment can be greatly reduced, the energy source of the paper mass is saved, and the packaging paperboard has better environmental protection performance; the polyurea can be formed by spraying, the processing is simple, and the manufacturing cost is lower.

In other embodiments, the polyurea spraying form can be only spraying the front or the back of the paperboard body or the front + side or the back + side, and the specific spraying form can be selected according to the actual situation of the package, the spraying thickness of the polyurea can meet the requirement generally within 1.0-1 mm, and the spraying thickness can be increased or decreased according to the requirement if special packages are available.

The above-mentioned embodiments are only for explaining the technical solution of the present invention in detail, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art should understand that all the modifications and substitutions based on the above-mentioned principle and spirit should be within the protection scope of the present invention.
