What are the raw materials for papermaking?

Wood, non-wood fiber, grass fiber, waste paper, pulp chemicals, ink, additives, dyes and fillers.

Paper raw materials mainly include the following:

1. Wood: including cork, Chinese fir, pine and other tree species. Wood is the main raw material of traditional paper industry, and pulp can be obtained after cutting, peeling, cutting and grinding.

2. Non-wood fibers: including flax, hemp, cotton, straw and other plant fibers. These fibers can be chemically treated or mechanically decomposed to obtain cellulose pulp.

3. Grass fiber: such as reed, reed, bamboo, etc. In some specific areas, grass fiber is often used as raw material for papermaking. Because of its rapid growth, it can replenish resources more quickly.

4. Waste paper: Recycled waste paper and cardboard can be made into pulp after deinking and bleaching.

5. Pulp chemicals: including bleaching agent and alkaline solution, used for pulp bleaching and fiber dispersion.

6. Ink: oily or water-based pigments and additives for printing.

7. Additives: such as adhesives, lubricants, antibacterial agents, etc. Increase the strength and luster of paper.

8. Dyes and fillers: used to adjust the color, luster and weight of paper.

These papermaking raw materials have different benefits and advantages. Let me give you some common material benefits.

1, wood:

Rich in resources: As a traditional raw material for papermaking, wood is relatively rich in resources, especially cork, Chinese fir, pine and other common tree species.

High fiber content: Wood fiber has tough texture and high fiber content, which can be made into high-strength paper.

Renewable: Wood comes from trees, and trees can be regenerated, so wood is a sustainable raw material choice.

2, non-wood fiber and grass fiber:

Sustainability: Non-wood fibers such as flax and hemp and grass fibers such as reed and bamboo grow rapidly, which is environmentally friendly, sustainable and recyclable.
