Acid-free paper, simply put, is paper that does not contain active acids. This paper is firm, strong and nearly neutral. The amount and color of this paper varies depending on the application, and it is a firm, strong, nearly neutral paper. When immersed in water, it produces a neutral or alkaline pH (7 or slightly higher). It is also lignin and sulfur free, which gives it good durability and makes it ideal for long-term storage of important items.

Sulfur-free paper is used by circuit board manufacturers as a special backing paper for the PCB silvering process to prevent the chemical reaction between silver and sulfur in the air. Its function is to chemically precipitate silver and prevent the chemical reaction between silver and sulfur in the air, which may cause Yellow, sulfur-free, which can avoid defects caused by the reaction between sulfur and silver. Sulfur-free, chlorine-free, and sodium-free special paper is supplied in large quantities. The pH value is neutral, and relevant inspection reports can be provided. Usage: Mainly used in silver-plated product packaging. Such as circuit boards, circuit boards, hardware terminals, food protection products

The paper of newsprint is soft, has good elasticity, and has good ink absorption performance, which ensures that the ink is fixed on the paper quickly; after the sheet is calendered, both sides are smooth and lint-free, so that the printed imprints on both sides are clearer and fuller; It has a certain mechanical strength; it has good opacity and is suitable for high-speed web printing. It can be used for bags, handbags, gifts, shoes, packaging, printing, etc.

Newsprint manufacturers are preparing for transformation. Due to the unstable supply of production raw materials, most domestic newsprint manufacturers are planning to switch production. In 2018, the China Press Association found during a survey that Shandong Jinyang Paper converted a newsprint machine into more profitable packaging paper after the 2018 Spring Festival. Shandong Shanxian Tianyuan Paper, which has been producing newsprint before, has not produced newsprint since 2018. As environmental protection policies become increasingly clear, the domestic newsprint market will usher in an inflection point around 2020. Only by taking precautions and planning ahead can various risks that may arise be resolved.
