Recycled paper is made of waste paper, which is crushed, decolorized and pulped, and then processed through various complex processes through high-tech means. 80% of its raw materials come from recycled waste paper, so it is known as environmentally friendly paper with low energy consumption and light pollution. There are many kinds of urban waste paper. After recycling, the manufacturers divide them into more than 60 categories, and use different types of waste paper as raw materials to make different recycled copy paper and recycled packaging paper. Generally, it can be divided into two categories: one is low-grade paper such as wall paper and toilet paper; the other is paper for books, magazines, copy paper, printing paper, postcards and exercise books. At present, many countries have produced and used these two types of paper. Among them, the raw materials for the production of recycled copy paper are office paper, offset books and binding paper and other types of urban waste paper with relatively good paper quality. The production process needs to be screened, dedusted, filtered, purified, etc. The process is complicated and the technology is very high. With the enhancement of people's awareness of environmental protection, recycled paper products will be more and more recognized and welcomed by people. Therefore, the recycled paper market is optimistic for paper manufacturers.
Features

6. Each batch of copy paper has to pass the high-speed test of professional photocopier, the curl is small, the jam rate is extremely low, extend the service life of office equipment, reduce the customer's comprehensive use cost.
7. All specifications are produced by fully automatic hob cutter to ensure excellent and stable cutting quality.
Misunderstanding of recycled paper
From the perspective of eye protection, it is not that the whiter the paper, the better.
According to the test, the brighter the paper, the stronger the light reflected under the fluorescent lamp, and the more harmful it is to people's eyesight. According to current international general standards, the whiteness of paper should not be higher than 84 degrees, and the whiteness of recycled paper is 84 to 86 degrees. The whiteness of the original wood pulp paper can reach 95 degrees to 105 degrees. At present, the most popular 83-degree natural color recycled paper in the world is because the natural color recycled paper can protect the two balls-the earth and the eyeball.
Comparison between recycled paper and plain paper
Comparison of physical components
In 1995, they set the standard of recycled paper to 25% recycled fiber, which was increased to 30% in 1999. A research unit in the United States found that when the circulating fiber in paper increases, the paper strength will continue to decline, but when the recycled fiber content exceeds 40, the paper strength will increase. Most people think that the recycling process will cause damage to the fiber structure, and the loss of aqueous hemicellulose and the original strength agent will weaken the overall paper strength. Later, some people refuted this claim after research, and found that even after the paper has gone through six cycles, the change in fiber length is only very slight, which shows that there are other factors that cause this phenomenon.
The research report of Stone and Scallan clearly pointed out that during the drying process, the surface area of ​​the pulp will shrink, reducing part of the binding ability, which often occurs on chemical pulp. Conversely, during the circulation process, the lignin in the mechanical pulp will be gelatinized, which will increase the binding capacity and elasticity, and the overall paper strength will increase.
Nowadays, many manufacturers of recycled paper are constantly improving in the production process, in order to make the characteristics of recycled paper log fiber as close as possible. For example, adding additives to chemical pulp or using chemical treatment steps to increase paper strength. But because the ink and dirt in the paper are not completely removed, the brightness will decrease with the increase of recycled fibers. In view of this, manufacturers will add some filler pigments or use different bleaching steps to increase the brightness. The characteristics of recycled fiber are not bad at all. It can increase the opacity of paper, reduce the reflection, and improve the quality of printed products.
