He then began to develop a low viscosity adhesive paper, which is the world's first blocking adhesive paper. The President was reluctant to support the plan but drew didn't give up. He took advantage of the small number of orders to continue his research, and a few years later drew invented cellophane tape. During world war ii, JOHNSON& co.
