Problems solved by technology

[0004] In view of the above-mentioned related technologies, the applicant found that in order to ensure the moisture-proof effect of corrugated cardboard, it is necessary to coat each layer of corrugated body with a waterproof coating, and each layer of corrugated body is arranged in a wave shape with uneven surfaces. It is very difficult to apply a waterproof coating to the corrugated body intact by technology, which leads to the problem of high defective rate of corrugated cardboard produced by this method, so it needs to be improved

Embodiment 1

[0042] The embodiment of the application discloses a corrugated cardboard. refer to figure 1, the corrugated cardboard includes a corrugated cardboard body 1 and a sealing filler 2; wherein, a filling groove 11 around the corrugated cardboard body 1 is provided on the side wall of the corrugated cardboard body 1, and the sealing filler 2 is installed in the filling groove 11, And the end of the sealing filler 2 is connected.

[0043] refer to figure 2 The corrugated cardboard body 1 includes a surface paper 12 and a corrugated body 13. There are two surface papers 12, and the two surface papers 12 are respectively arranged on both sides of the corrugated body 13, and the two surface papers 12 are arranged on the opposite side. Both are coated with a waterproof coating (not shown in the drawings) for preventing water vapor from directly intruding into the corrugated cardboard body 1; wherein, each peripheral side of the surface paper 12 protrudes outside the corrugated body ...

Embodiment 2

[0049] refer to Figure 4 The difference between this embodiment and Embodiment 1 is that the sealing filler 2 is set as a waterproof sealing strip 22, and the side of the waterproof sealing strip 22 away from the corrugated body 13 is on the same plane as the side wall of the corrugated cardboard body 1 .

[0050] The implementation principle of embodiment 2 is:

[0051] The cross-section of the waterproof sealing strip 22 is set in a rectangular shape, and the waterproof sealing strip 22 can be prefabricated in advance. Apply glue inside, and finally install each section of sealing and waterproof adhesive strips into the filling tank 11 , and use glue to bond and fix each section of sealing glue 231 in the filling tank 11 .

[0052] The waterproof sealant strip 22 can also be directly filled into the filling groove 11 with the waterproof sealant 231 , and the waterproof sealant strip 22 can be formed after the waterproof sealant 231 is solidified and formed.

Embodiment 3

[0054] refer to Figure 5 , the sealing filler 2 is set as a waterproof bundle 23, and the waterproof bundle 23 is formed by kneading several pieces of waterproof paper or waterproof thread into a round strip, and the sealing filler 2 also includes a water-proof bundle filled between the waterproof bundle 23 and the filling groove 11. Sealant 231.

[0055] The implementation principle of embodiment 3 is:

[0056] The waterproof bundle 23 formed by kneading waterproof paper or waterproof thread can be bonded and fixed in the filling groove 11 by using the sealant 231, and the waterproof bundle 23 can be wrapped by the sealant 231, thereby ensuring the overall waterproof ability of the waterproof bundle 23. The sealant 231 can also fill the gap between the waterproof bundle 23 and the filling groove 11 to ensure the sealing effect of the waterproof bundle 23 on the filling groove 11 .

[0057] The embodiment of the present application also discloses a corrugated box production...

Abstract

The invention relates to a corrugated board and a corrugated carton production process. The invention relates to the technical field of packaging materials. The corrugated board comprises a corrugatedboard body, wherein the corrugated board body comprises two pieces of surface layer paper and a corrugated body; the corrugated body comprises a plurality of layers of corrugated paper which are bonded together; the corrugated body is arranged between the two pieces of surface paper; the two pieces of surface layer paper are coated with waterproof coatings; a filling groove surrounding the corrugated board body by a circle is formed in the side wall of the corrugated board body; the filling groove is defined by the side faces, opposite to each other, of the two pieces of surface layer paper and the side wall of the corrugated board body; a sealing filling piece is arranged in the filling groove; and the upper side and the lower side of the sealing filling piece are connected with the twopieces of surface layer paper respectively. The process has the effect of improving the defective rate of corrugated boards.

Description

technical field [0001] The present application relates to the technical field of packaging materials, in particular to a production process of corrugated cardboard and corrugated cardboard boxes. Background technique [0002] Corrugated paper is a common material for paper packaging boxes. It is made of at least one layer of corrugated paper and a layer of cardboard (also called cardboard). It has good elasticity and extensibility. It is mainly used in the manufacture of cartons, the sandwich of cartons and other packaging materials for fragile goods. It is made of raw cardboard similar to yellow cardboard by beating with domestic straw pulp and waste paper, and then machined to make it into a corrugated shape, and then the surface is bonded with boxboard paper with an adhesive such as sodium silicate. The corrugated corrugated corrugated cardboard is like connected arched doors, which are arranged in a row with each other and support each other to form a triangular structu...
