What is the difference between imported kraft paper and Chinese kraft paper?
 
Water activated kraft paper tape manufacturers mainly from the use of raw materials, the production of kraft paper products and other aspects, a comprehensive description of the main differences between imported kraft paper and domestic kraft paper.
 
At present, the imported kraft paper in the domestic market mainly comes from the United States and Sweden. This paper takes these two kinds of kraft paper as an example to make a comprehensive comparison with domestic kraft paper.
 
1、 Difference of wood pulp used
 
1. Most of the imported kraft paper is bleached coniferous pulp, and a small part of hardwood pulp. Therefore, whether it is American Kraft paper or Swedish kraft paper, the wood pulp selected for the production of kraft paper is of high purity, high strength, good physical properties and good quality.
 
2. At present, few domestic kraft paper manufacturers have developed the integration of Forest Pulp and pulp. Most of the wood pulp used in the production of kraft paper relies on imports. Most of the wood pulp selected for the production of kraft paper is imported commercial pulp. Its purity is relatively poor, and the corresponding technical indicators are slightly poor. At the same time, the number of grams of domestic kraft paper is more extensive, from more than 20 grams to more than 400 grams.
 
2、 The difference between bursting strength and tensile strength
 
Compared with domestic kraft paper, the bursting strength and tensile strength of imported kraft paper are better than that of domestic kraft paper due to its relatively high purity of wood pulp.
 
3、 The difference of paper smoothness
 
Compared with domestic kraft paper, the paper surface smoothness of most American Kraft paper is not smooth due to the high content of long fiber needle pulp. For example, American GP kraft paper basically uses long fiber pulp, which sacrifices the smoothness of paper surface when its bursting strength is very high.
 
The smoothness and smoothness of domestic kraft paper are better than that of domestic kraft paper, while Swedish kraft paper usually pays attention to the unity of printing effect and physical strength, so the majority of imported kraft paper from Sweden is single light.
 
4、 Recommendation of high quality kraft paper products
