Automatic cardboard production line (or single-sided machine) technology for the production of starch adhesives
At present, the adhesive used in automated paperboard production lines (or single-sided machines) at home and abroad is commonly referred to as "raw rubber." The so-called "raw gum" refers to no adhesive force at room temperature, it will be heated to a mature gum by the high temperature on the paper, and it will have adhesive force. The production method mainly uses starch (mainly corn starch, and also other starches such as tapioca starch, wheat starch, etc.), and is made...
An Attempt to Produce Composite Board Paper from Corrugated Cardboard Production Line
Is it only possible to produce corrugated cardboard from a corrugated cardboard line? Faced with a huge amount of equipment, we are whimsical: to increase equipment utilization and give it new features, we must let "chicken into the water, duck shelves!" Our company originally planned to set up a set of paperboard composite equipment. After inspection, we discovered that the working principle of the equipment was similar to that of the gluing and drying machines of the corrugated board line....
How to Treat the Production Speed of Corrugated Cardboard Production Line
In the past two years, the development of the corrugated machinery manufacturing industry in mainland China can be described as rapid progress.

And several well-known domestic machinery and equipment manufacturers are also promoting such products. Water-based direct printing equipment factories such as Nanhai Dongfang, Shanghai Dinglong, Beijing Dobeck and Taiwan Changsheng, TCY, etc .; offline pre-printing machinery manufacturers such as Qingzhou's Egofa and Guangzhou Kesi Gao. It is...
Water-based printing of corrugated paper with high mesh line (2)
Plate selection of high net cable plate making The printing plate used for high screen printing has a hardness slightly higher than that of the general printing requirements. This is because this printing process requires a small amount of ink in order to accurately reflect the fine dots. If the printing plate is too soft, the ink transfer volume will be too large, which is not conducive to the control of the ink volume, and it is easy to appear faults such as color shift and network blocking....

Causes of corrugated cardboard crimp line break
Corrugated paper easily breaks during the process of crimping 1) The gap between the upper and lower pressure rollers is too small Adjust the gap between the upper and lower crimping rollers according to the corrugated shape of the cardboard and the thickness of the cardboard to maintain a reasonable pressure strength. For example, if the crimping strength is too small, it will not cause the crimping line to break. Cracking occurs, and this phenomenon occurs mostly in cardboard made from...
High-speed corrugated cardboard production line configuration

5.9 Installation of multiple machines The above mentioned are the installation of a single machine. If multiple machines are installed in a workshop, how should they be put in place? There are many factors that need to be considered for the installation of multiple machines. The following is a detailed analysis of possible situations. (Figure 5.19) 1. Installation of multiple single and double color machines Due to the short body of the single-color and double-color machines, the selection of...
Corrugated cardboard box knowledge collection - Bonding and problems (3)
(d) The principle of bonding corrugated cardboard: Starch gelatinization process, as shown in Figure 5 starch is composed of 100-10000 glucose combined polymer compounds, as shown in the following figure of starch granules, its size is about 2-100u. If observed under the microscope, the gelatinization phenomenon can be found, a starch grain (Figure 6) During the gelatinization process, it swells due to the absorption of moisture from the surroundings. From several times expansion to dozens of...
Corrugated Cardboard Types (1)
Section 1 Classification of Bad Boards In the production of corrugated board, there will be various kinds of unpleasant phenomena, and sometimes even unexpected undesired products will be produced. The most common types of unfavorable phenomena can be mainly divided into three categories: First, bad lamination, bad face paper bonding; 2. Adhesion of paper and paper edges is poor; 3, facial paper foaming; 4. Adhesion between A and B is poor; 5, in the paper, the paper appeared bad lamination; 6,...
Corrugated cardboard printing color consistency and layout accuracy (below)
Printing pressure The flexo pressure is generally 1-3 kg/cm2, and the corrugated box printing pressure is generally 1-2 kg/cm2. Because of the pressure of the printing plate and the reaction force of the impression cylinder, the phenomenon of light color and color cast tends to appear during the printing operation. When the amount of ink is “not enough”, the printing pressure of the printing plate tends to increase in an attempt. To achieve the ink requirements, the result is a serious edge...

Corrugated cardboard offset printing
We know that in the past there were three ways to print on corrugated cardboard: 1. Print directly on corrugated board with flexible or rubber; 2. Printed on paper with an offset press, and then composite the printed paper with corrugated cardboard; 3. In the production of corrugated board, a web-fed flexo printing machine is used to print the pattern on the uppermost layer of paper and then compounded. The corrugated board produced is a product that has already been printed. Generally, the...

Corrugated cardboard seesaw-1
2. Adhesion Mechanism of Core Paper and Face Paper The adhesion of corrugated core paper and face paper is mainly agglomeration and adhesion of starch adhesives, supplemented by osmotic adhesion and surface adhesion. The sizing penetrates the inner surface of the paper and the surface of the corrugating medium, and penetrates into the fiber gap of the paperboard to cause penetration adhesion. At the same time, the face paper and the corrugating medium and the adhesive surface are formed with an...

Zhongshan, Guangdong launched corrugated cardboard printing new technology
Zhongshan Keyu Trading Co., Ltd. of Guangdong Province recently developed a new technology for corrugated boxboard printing. This is the use of a sponge liner on the offset plate, which greatly improves the print quality of the corrugated box. Corrugated board printing pressure is too large, it will damage the cardboard, and the pressure will not affect the quality of the print. Keyu Company has repeatedly tested and put a sponge liner on the printing plate to make the ink transfer more uniform...

3. Thin line processing It is inevitable to adopt some thin lines in the design of corrugated boxes. We must pay attention to these lines. Because in the development process of the flexographic plate, the unexposed portion is washed away by the developer and the brush, leaving only the embossed portion of the graphic portion. Therefore, the width of the thin line must not be less than 0 5 mm. If it is an isolated line, the width should be increased appropriately. Small incontrasting lines and...
How to ensure the adhesive strength of corrugated cardboard
Corrugated board adhesive strength depends mainly on the quality of the adhesive and corrugated board production line sizing quality. Adhesive quality The quality of the adhesive depends mainly on the strength of the adhesive manufacturing process and the quality of the raw materials used. The main raw material used for the binder is starch, which generally uses cornstarch above industrial grade one. If starches with lower grades are used, due to their poor processing precision, impurities such...
Corrugated cardboard folding carton and tubular folding carton design features
Folding carton design features Folding cartons are generally made of folding-resistant cardboard with a thickness of 0.3-1.1 mm and can be transported and stored flat before being shipped. Both sides of the folding-resistant paperboard have enough long fibers to produce the necessary folding resistance and sufficient bending strength so that they will not crack along the indentation after folding. The main varieties of folding paperboard are manila paperboard, white paperboard, boxboard, noodle...
