Problems solved by technology

[0002] Tube paper is a kind of industrial thin steel paper with good water resistance. Tube paper is mainly used in the production of cores and pipes, industrial tubes, mulch tubes, fireworks tubes, textile tubes, spiral tubes, pagoda tubes, parallel tubes Tubes, various paper corner protectors, cartons, honeycomb cardboard, etc. The existing bobbin paper is relatively expensive, and it is made of coniferous or hardwood pulp. Some companies will use waste paper to reprocess it to save costs, but often The bobbin paper produced is not hard enough and relatively brittle. During transportation, the product is often difficult to avoid bumping. Therefore, the use of this bobbin paper will often cause the product to fall and be damaged. Therefore, how to use waste paper to make a high-strength Wear-resistant bobbin paper has always been a research topic for enterprises
