Tianzhang was established in 1996 and became a group company in 2011, mainly producing printing consumables, including copy paper, printing paper, fax paper and so on. Tianzhang brand ranks among the top in the country in the copy paper market, and has also obtained China Environmental Label and FSC Forest Certification.
 
Tianzhang has many types of packaging, among which the specifications of the new green Tianzhang are the most complete, 70g/㎡ and 80g/㎡ have 1, 5, 8 packaging, priority recommendation.
 
The paper thickness of 70g/㎡ is 101μm, which is higher than the 90μm required by the national standard for excellent products. The paper is thick, so the opacity is also high, the opacity is 94.3%, which is also greater than the national standard, and the ink is not easy to penetrate to the back, which is suitable for double-sided printing. The moisture content of the paper is moderately controlled, and it is not easy to curl corners, wrinkles and other phenomena, the paper is smooth, the printing speed is fast, and the paper is not jammed.
 
In fact, according to the paper parameters and user reputation, Tianzhang paper belongs to the middle and high-end level, and the performance is definitely better than Deli and Chenguang, but according to the copy paper quality supervision and random inspection report published by the Jiangsu Provincial Quality Supervision Bureau in the past two years, some models of copy paper in Tianzhang have excessive quantitative deviation and unqualified sizing. Among them, the sizing degree is a very important index, reflecting the ability of the paper to absorb ink, and the sizing degree will directly affect the clarity of the picture and text, the degree of color reproduction, etc., which to a certain extent reflects the quality control defects of Tianzhang.
