Causes and solutions of paperboard warping
The reason for the warping of cardboard: corrugated cardboard is too dry, the shrinkage ratio of the face paper and corrugated cardboard is not the same, and it is generally warped in the direction of the face paper.

Why are paperboard composite starch adhesives welcomed by paperboard factories?
As we all know, cardboard composite starch glue is made of edible corn starch after oxidation and compounding, compared with white latex, foam alkali and other adhesives have the following advantages:
How to detect the adhesion of the paper machine glue is enough?
There are several ways to check the adhesion of the paper laminator glue: 1. Feel test method: gently knead the pasted paper, if there is no foaming between the paper and the bottom plate, and the surface of the paper is flat, it indicates that the paste degree is enough. 2. Tilt test method: Tilt the pasted paper 45 degrees, if the paper does not fall off or slide, it indicates that the paste degree is enough. 3. Resin test method: Put a small piece of resin
A paper tube glue heater is a device used to heat glue. It usually consists of a heating element and a paper tube. The working principle of the paper tube glue heater is to transfer heat energy to the paper tube through the heating element, so that the glue in the paper tube is heated to a certain temperature. The heating element can be an electric heating wire or a heating plate, which transmits heat en
Research and application of modified starch glue
Modified starch glue is a common adhesive, which is obtained by chemical or physical treatment of starch. Modified starch glue has good adhesion, adhesiveness and low cost, so it is widely used in paper products industry. In terms of research, the research of modified starch glue mainly focuses on the following aspects: 1. Modification methods: Different modification methods of modified starch glue are studied, including chemical modification and physical modification. Chemical modification methods include esterification, etherificatio
Manual glue machine how to choose starch glue?
Carton packaging industry has a very special machine, that is, "manual gluing machine", with the development of technology, many carton factory laminating machine more advanced, from the initial manual gluing machine, to semi-automatic machines, and then to automatic machines, to the present high-speed laminating machine. Although crazy, many carton factories are still using manual gluing machine, although the speed of manual gluing machine is slow, but for zero single, loose single list, manual gluing machine is a best choice, so how to choose the starch glue of manual gluing machine?

The paper laminator glue produced by the board glue line is not uniform
After the paper and corrugated cardboard are mounted on the press, the glue line on the paper is not uniform, I believe that many laminating machine teachers have encountered this problem, then what is the cause of this problem, how can the glue line be uniform and the cardboard bond is still firm? The reasons for the uneven glue line of the cardboard made by the glue machine are as follows: 1, corrugated cardboard high and low 2. Uneven rubber roller 3, the glue is too thick, poor fluidity 4. There are impurities o
Laminated corrugated cardboard is uneven and warped
After corrugated carton lamination, the cardboard ends are warped and uneven, I believe many bosses and starters have encountered this problem, so what is the cause of this, and how can we make a good flatness of the cardboard. To improve warpage, the following methods are used: If the face paper is warped
Corrugated cardboard is not flat - showing flute/row flute/floppy
See other people's boxes do not show glue marks do not show fluting, box compressive strength good hard, but the surface of their own boxes a strip of corrugated lines, but also floppy no point hardness, you follow the method I said with glue, to ensure that you do not only look good boxes can also be load-bearing!
Starch glue laminated cardboard is not flat of - drip / offset printing
The face paper and corrugated cardboard laminated, like this laminated cardboard, from the face paper to look at a fixed position with obvious offset (color darker than normal face paper color and will not dry), although this is caused by the glue, but most of the reasons related to machine adjustment.
Methods of reducing moisture content of corrugated board
Customers and friends of carton packaging often ask us, can the moisture test of your glued cardboard reach 8? I would like to say that it is impossible to count on the glue completely, because the paper itself contains moisture. See the figure below:
Advantages and disadvantages of oxidized starch
Properties of oxidized starch: Oxidized starch is a kind of modified starch which is obtained by the action of starch and oxidant in acid, alkali and neutral medium to oxidize starch. Through oxidation, carboxyl functional groups are introduced into starch molecules, and to some extent, the degree of polymerization of starch macromolecules is reduced due to degradation. Therefore, oxidized starch is endowed with some unique properties, which can be widely used in textile, paper making, packaging, food an
Paper tube glue instead of polyvinyl alcohol
The special adhesive for paper tube and paper barrel is a special adhesive for paper barrel to make various paper tubes, paper barrels, paper cans and related paper products. With the rapid development of China's economy, the demand for paper tubes and barrels in daily necessities, textiles, light industry, packaging, leather and other fields is growing. Such as toilet roll paper inner core tube, textile bobbin, cloth, paper, leather, plastic film and other roll packaging paper tubes.
How to Use Paper Tube Glue Correctly
Non drying paper tube adhesive is a special adhesive for making various paper tubes, barrels, cans and related paper products. These paper tubes are generally mechanically rolled and bonded with kraft paper or other raw materials, and the adhesive used is called paper tube adhesive. With the rapid development of China's economy, the demand for paper tubes in daily necessities, textiles, light industry, packaging, leather and other fields is growing. Such as toilet roll paper inner core tube, textile bobbin,
Choose the right adhesive for cartons to reduce the production cost efficiently
At present, modern post press technology is gradually infiltrating into the specific production process, ranging from the design of technological process, the manufacture of advanced equipment, to the matching of adhesives and materials, etc., are gradually improving the production and manufacturing process, making efforts for a new round of high-speed and efficient productivity improvement. As a widely used adhesive product in the packaging industry, enlin adhesive has developed and produced a special adhesiv
How to distinguish the quality of starch glue
If the prepared starch adhesive can be used in production, it should be tested before use, only in this way can we ensure to produce carton products with good bonding quality. One. Sensory examination By observing sound, foam, color, silk to identify the quality of adhesives. 1. Listen:
What are the serious consequences of not roughening the corrugated board after bonding
Before the large-scale production of corrugated board, the production personnel will test the adhesive. The main test method is to tear the corrugated board and the face paper after the board passes the bonding tape to see if there is any "galling" phenomenon. If all "roughening" can be safely put into production. What about partial or no galling? This paper will analyze the causes and solutions of these phenomena. What is card board galling?
