摘要
主要研究了羧甲基纤维素的成膜特性及不同因素对此膜的物理和机械性能的影响．结果表明适当的羧甲基纤维素用量能使膜性质较好；中温干燥（65℃）能使膜具有较好的阻湿性；适量的增塑剂不仅使膜具有一定的抗拉强度和延伸率，而且不会明显提高透湿性；膜的厚度对膜的水蒸汽透过系数。
The film-formed property of CMC and the effect of different factors on the physical and mechanical properties of the edible film were studied. The results showed that proper concentration of CMC could present the film with good properties. CMC film obtained by drying at 65℃ possessed better function of barrier to water transmission. Furthermore, suitable amount of plashcizer could contribute to the film with a certain tensile strength and elongation, and had little effect on its WVP. The film thickness had much effect on the WVP. tensile strength and elongation
