The present study investigated, through laboratory testing, the physical and mechanical properties of recycled paper used to produce tubes. To do so, we used six types of paper with a weight average of 400 g / m² and once the laboratory tests followed the procedures of the Technical Association of Pulp and Paper Industry. There was significant difference between the roles studied in terms of physical and mechanical characteristics, and the paper type A1 had, in general, the best results, justifying its high price in the market. The A3 has the highest density, the data relevant to industry tubes, since these are usually sold by weight. It is concluded that all of the studied papers are suitable for tube production, being used in accordance with the customer's demands, since the price of the paper is what determines, most of the time, the tube value.
