Problems and Solutions of Direct Corrugation of Micro-Corrugated Cardboard
The first thing that should be considered in the direct offset printing of micro-corrugated cardboard is the uneven surface of micro-corrugated cardboard. Unlike the printing of plain paperboard, the printing of fine corrugated cardboard must take place on uneven surfaces caused by corrugations and troughs. Offset printing on uneven substrates is difficult to perform, and printing quality is difficult to guarantee. Substrate irregularities are a major challenge for fine corrugated board...
Improvement Method of Flatness of Cardboard Corrugated Board
Corrugated board flatness is one of the important indicators in the carton production technology. It is directly related to the quality of product printing, die cutting or notching. The poor flatness of corrugated board will result in a variety of arched shapes of corrugated paperboard, and it will be easily jammed when the mechanical printing and printing is carried out and cause the paperboard to be scrapped and be forced to shut down and clean up. Ink printing is not uniform and the color...
Solve the problems of corrugated cardboard
Nowadays, the requirements for the production quality of our carton factory are getting higher and higher, and the argument for the development of cardboard “lightweight” is a question that most colleagues in the carton factory are thinking about. The “lightweight” of cardboard, that is, the production of paperboard for paperboard, is becoming thinner and thinner. However, the possibility of the squashing of corrugated boards is greater. I share with you the practical experience at the...
Corrugated cardboard line to reduce loss of paper
It is well-known that the corrugated paperboard line is manufactured by a single-faced corrugating machine to produce corrugated and adhesively bonded single-faced corrugated cardboard. After passing through the bridge, it is sent to the sizing machine for coating the rubber-coated composite paper, and then enters the dryer for drying. Pressure lines, slitting, and cross cutting are required to make the box board. Obviously, the cause of the waste of raw paper, the reasons for the low yield of...
The Feasibility Analysis of Reinforced Sandwich Corrugated Cardboard Paper Packaging

The present situation of packaging is: corrugated cartons are used for packaging small food products such as foods, beverages,...
Corrugated cardboard degumming serious related factors
There are three major factors in the production of corrugated board: temperature, paste, and tension. For the operator, it is necessary to adjust these three elements to the corrugated box machine spare parts best conditions to produce high-quality corrugated board. Corrugated board degumming is also seriously related to these three elements. (a) The binder raw material does not meet the requirements, especially the content of the gray powder in the starch has a great influence on the adhesive...
Solve the problem of poor adhesion of corrugated cardboard
In corrugated board production lines, poor corrugated board adhesion (bubbling, degumming, and spurious particles) has occurred from time to time. The reasons are many, such as the high moisture content of the base paper, the improper control of the amount of glue applied in production, and the quality of the adhesive. The adhesive mechanism of the adhesive is the first problem that should be solved. If one knows little or little about the adhesion mechanism of adhesives, then when poor...

Corrugated cardboard graphic design and flexo plate making
The overall design level of domestic corrugated cartons is relatively low. In particular, there are very few carton pattern designers who have rich theoretical knowledge of corrugated carton packaging and practical experience in the corrugated carton flexographic printing process. The development of corrugated carton samples cannot be correct. Analyze the hierarchy order of graphic color printing and reasonably determine the number of screen lines of the printing plate. Therefore, the problem...
Several Quality Problems in the Production of Corrugated Cardboard
The corrugated paperboard production line has a complex structure. Production requires corrugated paper, temperature, adhesives, and speed to be synchronized. If a link goes out of control, quality problems will inevitably occur. At the same time, in the production process, the technical parameters, process design, quality inspection and other aspects of corrugated board are very strict. The qualified corrugated board can ensure the compressive strength and the ring pressure strength of the...
