According to the report in May, 2015 by Japan Paper Recycling Promotion Center, quantity of paper and paperboard product in Japan decreases is about 18% from 2007 to 2014. Japanese quantity of waste paper in 2014 is 21750000ton, the rate of collected waste paper is 80.8%. Nevertheless Japanese consumption of waste paper is 17190000ton, the rate of utilizing waste paper is 63.9%. It means that quantity of collected waste paper become bigger than quantity of utilizing waste paper, a lot of waste-paper is exported to East Asia (especially China). Balance of waste paper demand and supply in Japan has already broken. It could be expected that waste paper will be collected more and more, but it is difficult to solve the problem that all domestic collected waste paper is used, in order to increasing phenomenon of helpful to recycle, energy saving, environmental protection movement. It is considered that the usage of paper tube need to be expanded which is produced by waste paper. Paper tube has been widely applied in many areas, such as packaging industry, film rolls, adhesive-tape industry, furniture decoration, temporary structures in building and so on. For example churches could be made from paper. The mechanical property of paper tube need to be investigated to get wide application.

At current study, the mechanical property of 8 kinds of paperboards for paper tubes fabrication were investigated included tension, compression and peeling properties combining with anisotropic property. These kinds of paperboards have different mechanical properties but same dimension. By this method, the effects of different properties including tension, compression and peeling on mechanical property of paper tubes could be evaluated. A series of paper tubes with different layers was fabricated and the lateral compression test was carried out and evaluated. The fracture form of paper tubes and fracture position on paper tubes were discussed together with paperboards properties. The cause of delamination behavior of laminated paper was analysis based on the detailed observation and finite element analysis. From fracture process, it was found that the main fracture of paper tube is delamination during lateral compression action which was considered peeling action has a big influence. According to this phenomenon, acoustic emission (AE) and observation of peeling paperboard were conducted.
