Color kraft paper tape has very good bursting strength and tensile strength, which is a very good packaging material. However, color kraft paper tape also has some obvious disadvantages, that is, color kraft paper tape is easy to produce color difference. What are the reasons for color difference of color kraft paper tape?
 
If we encounter the color difference problem of color kraft paper tape, how can we solve these problems, that is, what are the color difference solutions of color kraft paper tape?
 
1、 Causes of color difference of color kraft paper tape
 
1. Color difference produced by raw material of color kraft paper tape
 
Both white color kraft paper tape and yellow color kraft paper tape are produced with wood fiber as raw material. Because wood fiber has different colors in different seasons, color kraft paper tape produced in different time periods will have different colors;
 
2. Color difference in the production of color kraft paper tape
 
In addition to the color difference caused by the use of different batches of materials, the color difference of color kraft paper tape will also occur due to different water temperature and uneven distribution of wood pulp in the production process of color kraft paper tape, which is the so-called color difference produced in the production process of color kraft paper tape;
 
3. Causes of color difference during storage of color kraft paper tape
 
After the color kraft paper tape is produced into base paper, it usually needs to be cut or rewound into different specifications of down roll or flat sheet according to the different needs of users. At this time, the color difference of color kraft paper tape will be caused by the change of temperature and moisture in different environment;
 
This paper analyzes the main causes of color difference of color kraft paper tape, then how can we avoid such problems as far as possible when encountering color difference of color kraft paper tape?
 
At this time, we need to take some technical means to avoid these problems as much as possible. First of all, we can avoid the trouble of color difference of color kraft paper tape to our use by the following methods:
 
1. Use the same batch of colored kraft paper tape as much as possible
 
When using, we try to purchase the same batch of color kraft paper tape produced in the same batch or close to the date, whether it is environmental protection color kraft paper tape or light color kraft paper tape. Because of the environment of the same date and the same batch of color kraft paper tape, the raw materials and colors are the closest;
 
2. Constant temperature preservation
 
Because the color of kraft paper tape will change due to the change of temperature and moisture in different environment, if we keep the color kraft paper tape in a constant temperature environment, it is not easy to cause color difference due to improper preservation;
