Also at that time used the bark mainly skin structure (ie mulberry leather), on parchment citrate has been called "Mr. Chu," said. Full sheet generally "Zhang" measure, cut sheets are measured at "Double" or "page." the same size and thickness of the paper , 500 called a "command." ordinary full-sheet for general use plywood packaging, a splint according to the paper size and thickness roughly packaged 7-20 Order verbally also called "splints" in. cut paper, carbonless paper, especially more upscale special paper, the general use of small package to "package" or "the" metering, carbon paper procurement, every package (this) several pages, carbonless paper bills, including (this) is mounted to " box "or" member. "such as ink-jet printing paper, copy paper. web generally" volume "measure, according to the size of several volumes refill roll as the" box "or" member. "Large quantities of paper with" t . "measure and is calculated primarily related to t measure are: ① each (volume) Paper Weight (kg) = length (m) × width (m) × weight (g / m2) ÷ 1000 ② tablet per ream of paper Weight (kg) = weight per sheet (kg) × 500 (p) ③ ton of paper orders (volume) per ream number = 1000kg ÷ (roll) Paper Weight (kg), or: ④ ton flat ream number = 2000g ÷ [length (m) × width (m) × weight (g / m2)] above formula ②, ④ flat paper dedicated to computing, ①, ③ suitable tablet, web calculation carbonless paper bills, gold Chau Paper (certified), non-carbon paper provided by the Xinxiang City Jinzhou New Materials Co., Ltd Xinxiang City, New Materials Co., Ltd.
