Chitosan film was immersed in NaOH solution with xylan to simply prepare active chitosan/xylan film. FT-IR, XRD, FE-SEM, AFM and XPS were used to evaluate the effects of xylan on the structure and morphology of chitosan film, and a wide variety of material characteristics of the chitosan/xylan composite films were investigated. The results showed that the xylan chains entered into the gap of chitosan film and became nodules, leading to strong hydrogen bonds and electrostatic interactions between chitosan and xylan. Moreover, the introduction of xylan not only resulted in stronger crystallinity and a more compact structure of chitosan film, but also had an important effect on the properties of chitosan film. The tensile strength, breaking elongation and anti-ultraviolet performance of the chitosan/xylan films were improved greatly with the increasing concentration of xylan; the water vapor transmission rate, water absorption rate and oxygen barrier property of chitosan/xylan composite films were higher than those of chitosan film; chitosan/xylan composite films still showed hydrophobicity when the xylan concentration was more than 1 %. The chitosan/xylan composite film has more potential to be used as food packaging than pure chitosan film.
