How to ensure the adhesive strength of corrugated cardboard
The bad sizing is mainly related to the equipment state, adhesive quality, and quality of the base paper of the corrugated cardboard production line. The common quality problems caused by poor sizing mainly manifest in the following aspects: 1, the phenomenon of dripping There are dirt on the rubber roller, such as paper scraps, agglomerates of starch and other foreign materials, etc., or the foreign material on the roll surface is blocked, causing the glue roller to fail to squeegee, and only...
Four-layer corrugated cardboard structure
Four-layer corrugated paperboard is used to coat two layers of corrugated paper with adhesives with special properties, so that the glue penetrates between the fibers of the paper, changes the softness of the paper, and composites the two layers of corrugated paper. They are glued together, rolled into a crucible under heating conditions, and then glued with the surface box cardboard to form a strong, stiff four-layer corrugated cardboard, the corrugated core type is double core paper adhesive...
The role of rubber roller in the formation of corrugated cardboard
In order to ensure the strength and good adhesion of the corrugated board, the corrugated board should be adjusted according to the configuration of the corrugated board production line. 1. The corrugated forming is ideal when the moisture content of the corrugated paper entering the single-sided machine is controlled between 9% and 12%. When the corrugated paper moisture content is higher than the above indicators, it can be taken to increase the warm-up area or reduce the speed; when the...
Color Printing of Corrugated Cardboard and Factors Affecting Ink Disposition
Over the years, the printing of corrugated board is merely to apply functional marks on the packaging box of corrugated cardboard, or to simply print in lines and words in monochrome, and the process is backward, inefficient, and costly.

Design of Micro-corrugated Cardboard and Improvement of Corrugated Roller II
Third, the quality of raw paper and process control The size and quality of the micro-corrugated board base paper lacks more options than the conventional crepe-type paperboard. When passing 150 g of ordinary corrugated paper around the C-Cave type dome, it can smoothly transition and form on a 1.25 mm radius dome arc, when the same base paper enters the G-type micro corrugated, . The transition and forming of the 16-millimetre radius dome arc is difficult, and the excessively small bending...

Analysis of Corrugated Paper Processing Problems in Corrugated Cardboard
The so-called crepe technology problems are mainly the accuracy of pasting and the quality of pasting. Now we will briefly analyze the above two issues. The precision of pasting is the maximum relative distance between the base paper and the edge of the base paper on the side of the specified rules after the pasted paper (ie, corrugated paper or cardboard) is attached to the paper (ie, colored paper). The range value, which is generally ±1. The factors affecting this value can be divided into...
Corrugated packaging recycling - corrugated cardboard expansion technology
BAIDU_CLB_fillSlot("858283"); At present, corrugated packaging that is environmentally friendly and can effectively utilize the value of renewable resources is a very hot development direction in the corrugated packaging industry. There are many environmentally friendly recycling methods for corrugated packaging, but they are basically recycled.

Special Forces in Corrugated Packaging: Introducing Four New Types of Fresh Corrugated Cardboard
The way to keep fruits and vegetables fresh is to reduce water loss, inhibit biological respiration and bacterial growth, and at the same time remove the ethylene gas that makes them aging and ripening. Preserving corrugated cardboard is processed manually from these aspects. 1. Laminated The plastic film soaked with antibacterial agent and fresh-keeping agent is made in corrugated cardboard, and then coated with CTM fresh-keeping agent on the inner surface of the corrugated cardboard. Its...

Corrugated cardboard and cardboard market
Corrugated board In the various industries hit by the economic recession in Western Europe, corrugated paperboard has suffered the most, and the decline in output caused by the economic downturn has caused inventory to decline. In the second half of 2001, due to lack of demand, the prices dropped significantly. At the same time, because most customers estimate that there is room for price reduction in the price of cardboard, they have been reluctant to open positions. We estimate that...
The corrugated design of corrugated cardboard and the structure of the corrugating roller
First, the type of micro-corrugated board design and corrugated roller structure One of the characteristics of the fine corrugated file is that it has a large number of turns and the corrugated base paper is lighter in weight and lower in strength. Taking the number of turns per 300 mm as an example: G type is 185±12, N type is 200±15, O type is 267, and B type is 50±2. With a pair of corrugated rollers of the same diameter, the number of turns in which the fine corrugations mesh is increased...

At that time, corrugated paper was used to pack light bulbs. By 1920, double corrugated paperboard came out, with a speed of 6m/min and a width of 800mm. Now it has reached a speed of...
Corrugated paper and cardboard other related tests
Smoothness: It refers to the degree of surface roughness of the paper, expressed in seconds. The detection principle is: the time it takes for a certain volume of air to pass through the gap between the surface of the glass plate and the surface of the sample under a certain degree of vacuum and pressure. The smoother the paper surface, the slower the speed at which the air passes, and vice versa, the faster the air passes through. Printing requires moderate smoothness, high smoothness, and...
