什么是牛皮纸？

　　What is kraft paper?

　　简而言之，牛皮纸是一种由软木浆制成的纸张。抗撕裂强度、破裂功和动态强度很高。多为卷筒纸，也有平板纸。   牛皮纸具有坚韧的强度，颜色呈棕黄褐色，经过半漂和全漂的牛皮纸还可呈现为奶油色或者白色。牛皮纸的抗撕裂强度和动态强度很高，柔韧结实，耐拉耐磨。主要用途十分的广泛。常应用与纸袋、作业本、信封等。

　　In short, kraft paper is a type of paper made from soft wood pulp. High tear resistance, fracture toughness, and dynamic strength. Most of them are roll paper, but there are also flat paper. Kraft paper has strong toughness and a brownish yellow brown color. After semi bleaching and full bleaching, kraft paper can also appear as cream or white. Kraft paper has high tear resistance and dynamic strength, is flexible and sturdy, and is resistant to tensile and abrasion. The main applications are very extensive. Commonly used with paper bags, workbooks, envelopes, etc.

　　牛皮纸的特性

　　Characteristics of kraft paper

　　包装牛皮纸，具有环保、再循环使用、节约成本等特点，随着整个国际市场对包装物环保性要求的日益提高，牛皮纸作为强度高，环保等，已成为包装的首选材料。   且牛皮纸还有一个特点，在过海关时牛皮纸包装材料是不需要另外提供检测的。

　　Packaging kraft paper has the characteristics of environmental protection, recycling, and cost saving. With the increasing demand for environmental protection of packaging materials in the international market, kraft paper has become the preferred material for packaging due to its high strength and environmental friendliness. And kraft paper also has a characteristic that no additional testing is required for kraft paper packaging materials when passing through customs.

　　当然，作为包装材料，其肯定是需要有高强度的抗压性能因为许多产品都是要经过物流运输的，而运输过程中很容易会出现一些包装问题，受到一定的挤压等，牛皮纸的耐折度、韧性都非常的不错。

　　Of course, as a packaging material, it definitely needs to have high compressive strength because many products need to go through logistics transportation, and packaging problems are easily encountered during transportation, such as being subjected to certain compression. The folding resistance and toughness of kraft paper are very good.

　　为了防止颜色不一致，需要潘通或CMYK来进行印刷。如果您想要单色印刷，专色印刷是的最佳选择!

　　To prevent color inconsistency, Pantone or CMYK printing is required. If you want monochrome printing, spot color printing is the best choice!

　　牛皮纸和牛卡纸的区别

　　The difference between kraft paper and kraft paper

　　1、重量的区别纸张的重量在150G以上的可称之为牛卡纸，反之则为牛皮纸。厚度厚的为牛卡纸，反之为牛皮纸。所以牛卡纸的硬度要大于牛皮纸。2、用途的区别牛卡纸主要用于一些大的生产厂家，作为产品的运输包装使用。而牛皮纸主要应用于生活中的纸袋、信封、作业本等。3、价格的区别由于牛皮纸和牛卡纸的厚度不同，所以如果按照单位张计算女的话，牛卡纸远远贵于牛皮纸。但是如果按照单位叠或者吨来计算的话，则是相反的。因为牛卡纸较厚，它表面需要处理的次数就越少，这样一来成本也就越低。

　　1. The difference in weight: Paper weighing more than 150G can be called kraft paper, while paper weighing less than 150G is called kraft paper. Thick paper is called kraft paper, while the opposite is called kraft paper. So the hardness of kraft paper is greater than that of kraft paper. 2. The difference in use of kraft paper is that it is mainly used by some large manufacturers as a transportation packaging for their products. Kraft paper is mainly used in daily life for paper bags, envelopes, workbooks, etc. 3. The price difference is due to the different thicknesses of kraft paper and kraft paper, so if calculated per unit sheet, kraft paper is much more expensive than kraft paper. But if calculated by unit stack or ton, it is the opposite. Because kraft paper is thicker, it requires fewer surface treatments, resulting in lower costs.
