In recent years, sustainable materials using natural resources have been developed to alleviate environmental problems. Bamboo has especially drawn attention because it has the fastest growth rate among various natural materials, and its fiber also has high specific strength and stiffness like glass fiber. Previously we proposed a high quality bamboo fiber extraction method with a machining center that overcame issues including lower shape accuracy and inefficiency caused by conventional extraction methods. In this paper, we implemented a fabrication of self-adhesive products using only bamboo fibers extracted with a machining center. Moreover, mechanical properties such as Young's modules and tensile strength of the product were investigated. In addition dumping characteristics were also studied. Influences of moisture rate of the products on the properties were evaluated by concerning a practical use. Finally, possibility of the product for bamboo fiber recycling in order to reduce environmental burdens in manufacturing phase was also addressed. As a result, it was found that the self-adhesive products using only bamboo fibers show some reasonable performances.
