Between thickness of ECO friendly kraft paper tape and gram weight!

ECO friendly kraft paper tape manufacturers, kraft paper tape thickness and gram weight has a certain relationship? In fact, many professionals engaged in the printing and packaging industry for many years may not know this problem. Nowadays, kraft paper tape wholesalers, in combination with the domestic literacy situation, promote kraft paper tape coefficient. It should be accurately said that it is the thickness coefficient of paper, not the thickness coefficient of which kind of paper, because it is OK. All the files are interrelated. We just take kraft tape as an example.

 

The coefficient of paper thickness and gram weight is thickness / gram weight = paper thickness factor. Therefore, the calculation method of paper thickness is: gram weight * paper thickness coefficient = paper thickness. Next, the method of calculating the weight of paper in grams is: thickness / paper thickness coefficient = gram weight of paper (grams of paper).

 

Therefore, we know the thickness coefficient of kraft paper tape. We can calculate the thickness of kraft paper tape and kraft cardboard with different weights by the thickness coefficient. Note: the thickness coefficient of each paper is different. You cannot use the thickness factor of kraft tape to calculate the thickness of other types of paper, such as coated paper or offset paper. Because the thickness coefficient of different types of paper is different, the thickness of kraft paper tape can not be used to calculate the thickness of other types of paper. Only the same type of paper thickness of the same brand can be calculated.

 

Relationship between thickness of kraft paper tape and gram number of kraft paper tape

 

There is a certain coefficient relationship between the thickness of kraft paper tape and the gram number. Kraft tape is not only related to this, but also to other types of paper. We mean the relationship between thickness and gram weight. Coefficient = thickness / gram weight, for example, it is known that the thickness of 350 grams of kraft board is 50 wires (0.50 mm). It is easier to know the thickness of other weights of the same type of paper of the same brand. How many grams of paper is 300 grams of cardboard? Using the above coefficient formula 0.14285 ≤ 50 ≤ 350, the coefficient of 350g kraft paper tape is 0.0.14285, which is convenient to calculate the thickness of 250 g kraft paper tape. Coefficient * gram weight = thickness (0.14285 ≤ 250 × 35.7 or 36 threads), so 250 g kraft paper tape is 36 wires. This method can easily and quickly let you know the thickness of the same brand of kraft paper tape, and the error is very small; another situation worthy of our attention is that the thinner the kraft paper tape is, the lower the thickness coefficient is. The thicker the kraft paper tape is, the higher the thickness coefficient is. The reason is that the smoothness of low gram kraft paper tape surface (thin gram weight) is relatively good, and the coefficient of low gram weight calculation does not change much, while the surface of high gram number (thick gram weight) kraft paper tape is relatively rough, and the measured thickness is higher, the calculation coefficient will also increase. Coated paper (such as copper board paper, white board paper, light coated paper, etc.), because the surface is smooth and the coating weight is greater than wood pulp, the thickness coefficient of Bible paper becomes smaller. So, the same paper thickness

 

 

 

Due to the thick surface, thin uncoated paper (such as kraft paper tape, cardboard paper, white kraft paper tape, double-sided tape, book cardboard, etc.) will have a large thickness coefficient.

 

 

 

In short, there is a coefficient relationship between the thickness and weight of kraft paper tape. Usually, the thickness of other paper can be calculated or the weight of kraft paper tape can be determined according to the thickness coefficient of kraft paper tape. The above calculation methods are interrelated and can be used flexibly in daily work.
