  Baijin is a professional  wet water kraft paper tape manufacturer . Its products are used for printing high-weight wet water kraft paper tapes, especially those with higher wood pulp content. When printing, the closer to the core, the degree of bending The larger it is, it will be difficult to restore the original shape after bending, resulting in failure to print. Why does the wet water kraft paper tape bend? Is there a way to solve this problem? The root cause of the bending of wet water kraft paper tape: The bending of wet water kraft paper tape is mainly because the temperature and humidity of the environment cause the paper fiber to absorb water or lose water. Since the transverse expansion rate of the fiber fiber is much greater than the longitudinal expansion rate of the fiber, the wet water kraft paper tape will occur when it absorbs water or loses water. Bending, in addition, there is a special feature that causes stress bending under the action of external stress. ...

  Baijin is a professional  kraft paper tape manufacturer . Today, I will introduce to you how to store wet water kraft paper tape. Many companies hope that when buying kraft paper tape, they can use it immediately and achieve zero inventory, but in fact this idea It can’t be realized. In the process of reproduction, various unforeseen situations will be encountered and zero inventory can not be achieved. Then the intelligence can reduce the inventory of materials as much as possible to shorten the inventory cycle. Since the kraft paper tape itself is greatly affected by external environmental factors, and once the paper performance changes, it cannot be recovered, so it will cause certain losses in subsequent production and processing. Therefore, attention should be paid to the storage of kraft paper tape. The base paper of kraft paper tape should not be stored in the open air as much as possible. If it is unavoidable to store it in the open air under certain circumstances, y...

The moisture content of  wet water kraft tape paper  has a great influence on printing. If the moisture is too low, the paper will be brittle, and static electricity will easily occur during printing. Today, Baijin wet water kraft paper tape manufacturers will introduce to you what factors affect the moisture content of kraft paper tape. If the moisture content is too high, it will make it difficult for the ink to dry, and the change of moisture will also have a great impact on the various properties of the paper. With the change of moisture, its basis weight, tensile strength, folding resistance, etc. will change. , The paper size of wet water kraft paper tape will also expand and contract, and even curl, curl, wrinkle, and ruffle. All kinds of wet water kraft paper tape paper have an optimal moisture content value. Under this value, the various properties of wet water kraft paper tape paper are in a good state. The best moisture content of the cast coated newspaper board is ...

  Printable kraft gummed paper tape  is a kind of kraft paper tape. Logos, patterns, etc. can be printed on it. So what are the printing techniques of printable kraft paper tape? Today, Baijin kraft paper tape manufacturers will introduce to you. 1. First of all, pay attention to the color of printing. Since ordinary kraft paper itself is dark brown, the effect of printing ink is very different from the effect of printing on bleached paper. Therefore, it is recommended to use brightly colored inks and use more eye-catching colors, so that the printing effect is better. Soft colors and light colors are difficult to achieve the desired ink density, opacity, and abrasion resistance. In addition, if necessary, a little white can be added to the ink first, which will help achieve the desired soft tone or light color. 2. Reasonable selection of ink, flexographic printing is generally better, and it is not suitable to use an offset printing machine. Because the surface of kraft paper...

There are many factors that affect the price of  kraft gummed paper tape , but what factors usually affect the price of kraft paper tape? From the actual situation, the factors that usually affect the price of kraft gummed paper tape are the raw materials used in production, the production process and the quality requirements. 1. The impact of kraft paper tape production materials on the cost price The raw materials used in kraft paper tape have the greatest impact on the price of kraft paper tape. Generally speaking, the commonly used raw materials for kraft paper tape are softwood pulp, bamboo pulp, hardwood pulp and waste paper pulp. Generally speaking, the price of kraft paper tape produced with softwood pulp is much higher than that of other paper pulps. At the same time, the price of kraft paper tape produced with different grades of raw materials is also quite different. For example, the mature kraft paper tape using bamboo pulp and high-grade bamboo Compared with the kraft ...

  The   kraft paper tape   must be moisture-proof. If the kraft gummed paper tape  is damp, it will greatly affect its use effect, especially when it is raining, the humidity outside will be relatively high, and it must not be placed outdoors. In addition, it should be stored Store in a dry place to avoid damp kraft paper tape. In addition, the paper fiber of kraft paper tape has good water absorption, so the ambient humidity has a great influence on the humidity of the paper. To control the humidity of kraft paper tape, the temperature and humidity of the warehouse must be controlled, usually the temperature is controlled at 18- 24 degrees Celsius, the relative humidity is controlled at 60%-65%. Regularly check the bottom card board for damage and prevent direct contact between the kraft paper tape and the ground. The card board uses a really fast flat board instead of a strip plate, which can greatly reduce the direct contact surface between the kraft paper and the...
