With the implementation of the “ban on plastic” and the enhancement of everyone’s awareness of environmental protection, the usage rate of plastic bags has been greatly reduced, and everyone has begun to use environmental protection bags or paper bags. As we all know, paper is a resource that can be recycled and reused. The raw material for papermaking is mainly plant fibers. In addition to the three main components of cellulose, hemicellulose and lignin, there are other components with a small content. Such as resin, ash, etc. Let’s discuss the difference between paper bag paper and kraft paper.
First of all, the production process of paper bag paper and kraft paper is very similar. Sack paper is produced using wood fiber from softwood and kraft pulp. However, the quality of paper bag paper is generally lower than that of kraft paper, because, in order to save production costs, some enterprises will add some cotton stalk pulp, bamboo pulp, etc., and some rags will be added to those with poor craftsmanship. Therefore, paper bag paper The quality of paper is not fixed and has great fluctuations. At the same time, paper bag paper has better mechanical strength, so it is usually used as a packaging bag, mainly for packaging cement, fertilizers, etc. In addition, now, the packaging of most products requires air permeability, so the air permeability of paper bag paper is also relatively good.
The types of kraft paper are more abundant, which can be distinguished from the aspects of color, use and raw materials. In addition, the strength of kraft paper is relatively large, which is one of the most important characteristics that distinguish it from other papers. At the same time, kraft paper is very strong and can be used to pack some bulk products. In terms of grades, kraft paper can be divided into three grades: U, A and B3. In addition, different products have different quality requirements. At the same time, different quality means different costs, so companies need to make their own choices. In addition, paper bags made of kraft paper are generally small paper bags, and the size of paper bag paper is uncertain.
In short, the proposal of the plastic restriction order has promoted the development of kraft paper, and now people are buying kraft paper bags, which are environmentally friendly and can be used for a long time, making a certain contribution to resource and environmental protection. Therefore, the use of kraft paper bags is advocated. Kraft paper bags are strong, durable, beautiful and environmentally friendly.
