| description | The invention discloses packaging bag paper and a production method thereof.The production method comprises the steps that coastal coniferous wood chips serve as main raw materials, and fine fibers larger than 100 meshes and other parenchyma cells are removed through a classified screening technology after pulping is conducted; the problems of insufficient fiber fibrillation caused by virtual high slurry freeness and low tensile energy absorption and air permeability of finished paper are solved; high-concentration pulping and low-concentration pulping are combined, auxiliary materials are added, the packaging bag paper is produced under the combined action, the tensile strength and folding resistance of the paper are improved, the wet strength and tensile resistance of the paper are improved, the retention of pulp is improved, and therefore the high-strength and high-air-permeability packaging bag paper is produced.
