    • An improvement in water-soluble polysaccharide films, such as pullulan films, by inclusion of carboxymethylcellulose (CMC) in the film is disclosed herein. The films exhibit surprisingly improved physical properties such as tear strength, and retain good water-solubility. The films optionally include other additives such as gelatin, plasticizers, and surfactants. Methods of making the films include first dissolving the polysaccharide polymer, such as pullulan, in water, heating the solution, next admixing gelatin, then CMC, and then optional ingredients including plasticizers and more water if desired.
    • 本文公开了通过将羧甲基纤维素(CMC)包含在膜中的水溶性多糖膜,例如支链淀粉膜的改进。 这些膜表现出惊人的物理性能如撕裂强度,并保持良好的水溶性。 膜任选地包括其它添加剂,例如明胶,增塑剂和表面活性剂。 制备膜的方法包括首先将多糖聚合物如支链淀粉溶解在水中,加热溶液,然后混合明胶,然后将CMC,然后任选的成分,包括增塑剂和更多的水,如果需要的话。
