Little knowledge of kraft paper bag making

u200bKraft paper bags are individually divided into 2 types of peritoneal paper bags and non-peritoneal paper bags

u200bThe peritoneal paper bag has a plastic coating on the surface. This kind of paper bag looks relatively high-grade, waterproof, and has a good load-bearing capacity, so the price of this kind of paper bag is definitely on the high side.

u200bNon-peritoneal paper bag, this kind of paper bag is usually made of kraft paper, which is more convenient, and the load-bearing capacity of kraft paper is relatively good. The price is relatively cheap.

u200bWhen purchasing paper bags, you often think that the thicker the paper bag, the better, and the thicker one is better. This misunderstanding.

u200bThere are 2 kinds of kraft paper. The first kind of domestic kraft paper (not all wood pulp kraft paper) is mixed with waste paper pulp of a certain proportion during papermaking. At times, the thicker paper will be used, and the original paper of 200-250 grams will be used, so the basis of the thicker kraft paper bag is the paper bag made of domestic kraft paper.

u200bThere is also a kraft paper made of wood pulp, 100% wood pulp, without any waste mixed in papermaking. The characteristics of this paper are that the wood fiber weft is superior to the tensile force of long paper, and the price of this paper is higher It is about twice as expensive as the kraft paper that is not made of wood pulp. Although the paper is not thick, it bears very well. Therefore, it is quite possible to use 100-120 grams of base paper when making individual portable paper bags. This kind of kraft paper is mainly exported.

u200bWhite kraft paper - whether it is domestic or exported, it is 100% wood pulp kraft paper. If you add waste, you can't make red. White kraft paper bags are definitely the most expensive paper bags in the production of portable paper bags.
