This result indicated that an ordered matrix structure of the film component managed to form. It was also found that no interfaces were observed in the blend or in the bi-layer film, indicating a high compatibility between components, yielding a relatively smooth and compact morphology. From the result, it was hypothesized that
interaction between gelatin molecules and CLC could take place at the interface of the bi-layer film. These results suggested that the compact structure of the resulting films might be responsible for the film
