The Difference Between A3 Kraft Paper And Paper Bag Paper

Paper bag paper is similar to kraft paper, mostly produced from softwood sulfate pulp. Domestically, some are also produced using a blend of bamboo pulp, cotton stalk pulp, and rag pulp. Therefore, paper bag paper has high mechanical strength and is generally used to make packaging bags for cement, pesticides, fertilizers, and other industrial products. To meet the requirements of filling, paper bag paper needs a certain degree of air permeability and a relatively high elongation.

Kraft paper includes linerboard, cement bag paper, high-strength corrugated paper, and brown cardboard. Kraft paper is a tough, strong, and yellowish-brown high-strength packaging paper made from softwood sulfate unbleached pulp. It can be categorized by appearance into single-sided gloss, double-sided gloss, striped, and unstriped varieties, with slightly different quality requirements. Kraft paper is mainly used to make small paper bags, document bags, and inner packaging for industrial products, textiles, and daily necessities. Kraft paper is divided into three grades: U, A, and B.
