Effects of different pulping conducts on mechanical properties of celery paper were analyzed in order to raise the tensile strength. Four kinds of combined pulping conduct were organized and four types of sample celery paper were prepared under the condition of middle scale production. Several reports of fiber analyses were given by Swedish L&W fiber tester. The structure characteristics of celery paper were presented through the photograph of Olympus microscope. Mechanical property reports were issued by authorized department. After analysis of fiber and structure as well as property, the maximum tensile strength was 1.765 times as much as the minimum among four types of sample celery paper. Therefore different mechanical pulping conducts really could raise tensile strength of celery paper.
