PVA water-soluble fiber helps to produce paper bags

At present, double-tape paper, newsprint paper, coated paper, and tax paper, which are made by domestically-added paper-making PVA water-soluble fibers, have been used successfully. The paper-bag paper and its products are being used in Fujian, Guangdong, and Gansu, and are welcomed by users.

Paper-making PVA water-soluble fibers form hydrogen-bonding forces with the pulp's fibers from the free radicals of their molecules, and because the strength of the water-soluble fibers is much higher than that of any pulp fiber, they act as a bonding agent in the semi-dissolved form of the process. The elongation, tearing strength, elongation strength, folding endurance and printing surface strength of the finished paper are greatly improved without affecting the ink absorption performance of the paper. The poorer papermaking pulps (waste pulp, straw pulp, wheat straw pulp, reed pulp) can be used to produce higher quality paper, which greatly reduces the cost of raw materials.

After adding paper-made PVA water-soluble fiber, it can be done under the condition of the same production quality, which can greatly reduce the amount of wood pulp added, reduce the consumption of wood, and save resources. Paper-making PVA water-soluble fiber has excellent gas-resistant properties, does not change during long-term storage in sunlight and air, and can improve the shelf life of pulp. The paper produced by adding PVA water-soluble can be completely recycled. After the water-soluble fiber is dissolved in water, it will be naturally biodegraded in water and will not cause any pollution to the environment, which is conducive to environmental protection.

At the same time, the adhesion of the water-soluble fibers caused by melting or semi-melting when passing through the drying roller is enhanced, and the air permeability of the finished paper can be improved.
