The raw paper is high in quality, is high in strength, toughness, delamination resistant strength and anti-tear performance, is excellent in softness and size stability, has the performance of resisting acid, alkali and high-temperature, and has excellent binding strength to different sheet materials.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a positioning paper base paper and a production method thereof. Background technique [0002] Positioning paper base paper is a special technology supporting paper for the production of washi tape in the adhesive industry. It is mainly used for the transfer and positioning of various decals. It is suitable for different adhesive forces according to the different processing methods of the laminated surface. [0003] Positioning paper base paper has high performance requirements, complex manufacturing process, and high technical difficulty. Currently, positioning paper base paper on the market has low strength, poor toughness, easy delamination, hard paper, poor dimensional stability, poor acid and alkali resistance, and There are disadvantages such as poor high-temperature performance and poor adhesion. Therefore, there is an urgent need for positioning paper base paper that c...
