Detailed Description

The present invention will be further described with reference to the following description and embodiments.

As shown in fig. 1, the waterproof and color-changing corrugated cardboard comprises an inner layer oil layer 1, an inner waterproof layer 2, a corrugated inner paper layer 31, a corrugated core paper layer 32, a corrugated surface paper layer 33, an outer waterproof layer 4, a microfibrillated cellulose coating layer 5, a color layer 6, an outer layer oil layer 7 and a color-changing layer 8 which are sequentially stacked from inside to outside.

As shown in fig. 2, the waterproof color-changing corrugated case comprises a case body 101 formed by folding a waterproof color-changing corrugated board and a printing coating on the inner side and the outer side of the case body, wherein the case body 101 is designed with a closed tear line 102, the tear line 102 encloses to form a color-changing area 103, the printing content of the part is a personalized pattern, and the part can be used as a water writing board after being torn.

The printing coating outside the box body consists of an outer waterproof layer 4, a microfibrillated cellulose coating layer 5, a color layer 6, a surface oil layer 7 and a color-changing layer 8 from inside to outside respectively, the inner side of the box body consists of an inner surface oil layer 1 and an inner waterproof layer 2 from inside to outside, the middle of the outer side of the box body and the inner side of the box body is a corrugated board 3, and the corrugated board 3 consists of a corrugated inner paper layer 31, a corrugated core paper layer 32 and a corrugated surface paper layer 33 from inside to outside.

Firstly, in order to enhance the waterproof performance of the corrugated board, a waterproof coating layer (a mixed solution of polyvinyl alcohol, sodium carboxymethyl cellulose, oxidized starch and a water repellent agent for paper) is uniformly coated on the outer surfaces of the surface paper, the inner paper and the middle paper in the forming process of the surface paper of the corrugated board so as to further enhance the waterproof performance of each layer structure of the corrugated board.

And secondly, uniformly coating a microfibrillated cellulose coating layer 5 on the outer surface of the surface paper (namely the corrugated surface paper layer 33) coated with the waterproof coating layer to further enhance the surface strength of the corrugated paperboard, and simultaneously filling tiny pits on the outer surface of the surface paper by the microfibrillated cellulose coating layer 5, so that the outer surface of the surface paper is smoother and the surface smoothness is increased. The uniform transfer of the printing ink is ensured, so that the printing plate has more uniform contact pressure when being contacted with the surface paper of the corrugated board during the flexographic printing, the printing ink is more uniformly transferred, and the coloring is better.

In addition, the outer surface of the liner paper (namely the corrugated liner paper layer 31) coated with the waterproof coating is coated with an inner layer oil layer 1, the inner layer oil layer 1 has scratch resistance, the waterproof layer is protected from being damaged, and the inner layer oil layer 1 has a certain waterproof effect.

The color layer on the microfibrillated cellulose coating layer 5 is formed by printing through flexo transfer watermark ink, is used for presenting information patterns such as design patterns, characters and the like, and simultaneously realizes the aim of environmental protection.

An outer oil layer 7 is printed on the color layer 6, and the outer oil layer 7 is used for the scratch resistance of the color layer 6 in the transportation and use processes, so that the color layer 6 has a protection function and a certain waterproof function.

Finally, a color changing layer 8 (water color changing ink) is printed on the outer layer oil layer 7, and the color changing layer 8 is positioned on the surface of a color changing area 103 formed by the enclosing of the tearing lines 102 and can be torn off to be used as a water writing board.

A waterproof color-changing corrugated carton is manufactured as follows:

1. respectively manufacturing an offset plate, a silk screen plate and a carton box structure design according to the required printing content and the printing area of the color-changing area;

2. in the process of forming the corrugated board, a layer of waterproof layer is coated on the outer surfaces of the corrugated inner paper layer 31, the corrugated core paper layer 32 and the corrugated surface paper layer 33;

3. coating an inner layer oil layer 1 on the outer surface of the corrugated inner paper layer 31 coated with the inner waterproof layer 2;

4. coating a microfibrillated cellulose coating layer 5 on the outer surface of the corrugated surface paper layer 33 coated with the outer waterproof layer 4;

5. printing a color layer 6 on the microfibrillated cellulose coating layer 5 by an offset printing process;

6. respectively printing surface oil on the surfaces of the color layer 6 and the inner waterproof layer 2 by a UV printing process;

7. the outermost discoloration layer 8 is printed on the surface of a discoloration area 103 formed by enclosing a tear line 102 of a case 101 by a screen printing process.

The inner waterproof layer 2 and the outer waterproof layer 4 are waterproof coating layers, and the waterproof coating layers are made of mixed liquid of polyvinyl alcohol, sodium carboxymethyl cellulose, oxidized starch and paper water repellent agent.

The utility model provides a pair of waterproof corrugated container board and waterproof corrugated container case that discolours has following advantage:
