From wood to pulp, to pulp, paper, and paper products

Packaging paper refers to a class of paper used for packaging purposes, generally used for downstream household appliances, daily chemicals, food and beverage, cigarettes and other industry products packaging. The main types of wrapping paper include corrugated paper, box board paper, whiteboard paper and white cardboard. Among them, box board paper and corrugated paper are mostly used in the fields of home appliance packaging and daily chemical packaging, and white board paper and white cardboard are often used for packaging cigarettes, food, pharmaceuticals and cosmetics.

The industrial chain of wrapping paper is "pulp - paper - all kinds of paper downstream". Looking at the subdivision of the packaging paper industry, according to the production of different raw materials can be roughly divided into two categories. First, corrugated paper and box board paper, the production of raw materials are mainly straw pulp and waste paper. Corrugated paper is mainly made of natural hardwood semi-chemical pulp, cold alkali pulp or natural alkaline straw pulp or with waste pulp, which is sent to the circular screen multi-cylinder paper machine after free beating. The raw materials used for box board paper are sulfate wood pulp, waste hemp pulp, cotton stalk pulp, waste paper pulp and rice straw pulp. The second is white board paper and white cardstock. The raw materials of each layer of white board paper are mostly composed of wood pulp, grass pulp and waste pulp, while the white cardstock uses 100% wood pulp as raw material. The middle reaches are papermaking enterprises, and the downstream paper products are mostly used in the consumer goods market, of which box board paper and corrugated paper are the mainstream. The packaging paper industry is a typical resource-constrained industry, and the supply of raw materials largely affects the profitability and development of enterprises.
