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



The paper industry is a typical long-chain, asset-heavy, long-cycle industry with diverse needs: the typical paper industry chain is "forest-pulp-papermaking - all kinds of downstream paper". Among them, the cultivation of rapid growth forest for pulping requires reserve forest land and cultivation, and the maturity cycle of trees is longer, requiring at least 5 years to be harvested for production. The production of pulp and machine-made paper needs to purchase large paper making equipment and supporting production capacity, the cycle is about 2-3 years; The growth rate of all types of downstream demand has slowed down after experiencing China's high-speed growth stage, and cyclicality is gradually replacing growth.

According to the national economic industry classification standard, the paper industry mainly refers to the paper and paper products manufacturing industry, including pulp manufacturing industry, paper industry, paper products manufacturing industry three links; Therefore, the paper industry is highly related to some basic industries, such as forestry, agriculture, printing, packaging, machinery manufacturing, chemical industry, environmental protection and so on. In general, the paper industry has the characteristics of intensive technology capital, significant economies of scale, high resource dependence and consumption, and relatively dispersed industry concentration.

I. Wood

According to plant classification, wood can be divided into two categories, gymnosperms commonly referred to as cork or coniferous trees. Angiosperms are called hardwoods or broad-leaved trees, or deciduous trees or evergreen trees.

Common softwood pulp types are: Scandinavianpine, Radiatapine, Southernpine, redceder, lodgepolepine, ceder, hemlock, White pine is whitespruce (whitespruce), blackspruce (blackspruce), Douglas pine (also known as Douglas Fir, douglasfir), larch (larch), balsamfir (balsamfir), alpine fir (Alpinefir), etc.

Commonly used broad-leaved wood pulp species are: eucalyptus, acacia wood, poplar, birch, maple and so on.

Two, pulp

Pulp is a fibrous substance made from plant fibers by different processing methods. It can be divided into many subdivisions according to the source of raw materials, processing methods, processing degrees, etc., and can be widely used in papermaking, artificial fibers, plastics, chemical and other fields.

Pulp is mainly divided into wood pulp, waste pulp and non-wood pulp according to the source of raw materials. Wood pulp is divided into two categories, respectively, coniferous pulp (including masson pine, larch, red pine, spruce and other species of wood pulp) and broadleaf pulp (including birch, poplar, linden wood, eucalyptus, maple and other species of wood pulp), generally coniferous pulp has stronger toughness and stretchability than broadleaf pulp, so in the use of wood pulp is usually mixed with a certain proportion of coniferous pulp to enhance paper toughness; Waste pulp is the paper pulp which is sorted and screened after the waste paper is recycled, soaked with warm water, and then repulped for reuse. There are three main types of non-wood pulp: grass fiber pulp (such as straw, wheatgrass, reed, bamboo, bagasse, etc.), bast fiber pulp (such as hemp, kenaf, flax, mulberry bark, cotton stalk bark, etc.) and seed wool fiber pulp (such as cotton fiber, etc.).

3. Paper Making

Papermaking is the dispersion of the resulting pulp to obtain evenly interwoven sheets. Paper products are usually divided into cultural paper, wrapping paper, household paper, and special paper according to the use of finished products: (1) Cultural paper covers all printing and writing paper, including newsprint, uncoated cultural paper (double-adhesive paper, writing paper, lightweight paper, electrostatic copy paper, etc.) and coated cultural paper (mainly coated paper); (2) Packaging paper covers all paper packaging raw materials, including cardboard (white board paper, white cardboard, corrugated paper, box board paper, kraft paper, etc.); (3) Household paper (toilet paper, diapers, etc.); (4) Special paper.

Cultural paper refers to the writing and printing paper used for disseminating cultural knowledge, which is mostly used for information transmission and cultural inheritance, mainly including uncoated printing paper, coated printing paper and newsprint.

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.

Household paper is mainly divided according to the use of scenarios, and household paper is generally used in daily life scenes. From the perspective of household paper market segmentation structure, toilet paper is the most important product of household paper.
