Paper and Packaging Materials
Paper and Packaging Materials
The invention of paper can be considered an important cornerstone in the civilization of mankind. Although opinions differ on the exact time of its invention, but the first documented invention is credited to Ts’ai Lun, who was a Chinese official of the Imperial court during the Han dynasty (around 105 AD). The invention of first sophisticated paper-making machine took a long time to coming though, in the year 1803. Paper is a highly engineered product made primarily from wood cellulose, which is the most abundant chemical compound obtainable from plant. Paper finds use in the manufacture of a number of varied products like books, notepads, magazines, food containers, tissue papers, cartons, corrugated boxes, packaging materials etc. The products range from very delicate to very tough items. The various types of paper products are manufactured as per their intended uses, and hence their qualities need to be assessed properly. Modi Laboratary has been providing accurate and reliable testing services for the various paper products for quite some time.
