Chenguang Stationery is a comprehensive stationery company focusing on the stationery business, covering a wide range of product areas. Although photocopying paper is not M&G's main business, M&G's financial resources accumulated over the years have introduced advanced Metso paper machines, with online monitoring systems, both hardware and software can reach the domestic first-class level.
 
The thickness of Zichenguang 70g/㎡ copy paper is 96μm, which is 90μm larger than the national standard of excellent products, and it has weight in the hand. The opacity reaches 95%, which is excellent among the same amount of paper, and even if it is printed on both sides, the handwriting will not be transparent, which helps to save paper. The water content of the paper is about 4.8%, the moisture is moderate, the paper will not be jammed due to too moisture, and it will not be curled and wrinkled because it is too dry, and maintaining a good flatness is conducive to passing the machine and writing.
 
However, Chenguang is the same as Deli, after all, it is not a company focusing on the production of paper products, but a comprehensive stationery enterprise, plus the sales volume is very large, so the quality is unstable, although the relevant departments did not find quality problems in the sampling, but did receive a lot of consumer complaints.
