Japanese Market News Paper Paper comes in a large range of types, but here the term is used to refer only to kinds of paper such as newsprint, printing paper and copier paper. Cardboard for corrugated cardboard boxes is not included. These are mixed together in different proportions depending on the type of paper being made. Cardboard is made mainly from waste paper, but to make paper, which requires a high degree of whiteness, a high proportion of wood pulp is used.
Pulp is imported mainly from North America and Scandinavia.
Wood pulp can be divided into machine-made pulp and chemically treated pulp according to the method of production. Machine-made pulp is made by crushing wood, and the approximate yield is a relatively high 95 percent. It is, however, lacking in whiteness and strength and so is used largely for newsprint. The world's leading producer of paper is the United States, with an output of some 86 million tons. Third is China, followed by Canada, Germany, Finland, Sweden, France, South Korea and Italy.
